Oxidation and Reduction in Organic Chemistry Tutors

Oxidation and Reduction in Organic Chemistry TutorsOxidation and reduction are one of the main forms of chemical reaction. These two types of reactions involve a change in one material to another. The catalytic nature of oxidation and reduction can sometimes determine a person's reaction in an organic chemistry classroom. In some cases, this reaction is difficult to pinpoint because the person is only reacting to the reduction (the reaction that is not catalytic) of one type of substance to another.When the reduction is not known, the reduction process usually involves combinations of oxygen and hydrogen. The oxidant (reduction) should usually be in the form of water and the oxidation of the water. A water-oxygen system is the common combination used in many organic chemistry laboratories.To reduce something to something else, oxidants must react with one another. Oils are a form of reducing agent. For example, when a water-oxygen system is used in a lab, the water can be used to par tially reduce oil. The reduced oil then can be used in a lab setting. A reduction can occur during a reaction and during the reaction process.Oxidation and reduction are a chemical reaction that can be viewed as the chemical replacement of one substance with another. This process is known as oxidation or reductive. The oxidation may be catalytic or non-catalytic.There are several types of oxidation and reduction. Catalytic oxidation is one form of oxidation and the opposite of the reduction. A carburizing reaction is another type of oxidation and the reaction does not result in a reduction of any type of substance. The catalytic oxidation results in a reduction.Reduction is one of the more prevalent and most useful types of oxidation. Reduction can be used to remove an alkali metal from a solution. It can also be used to remove a saturated or partially saturated anhydrous metal from a solution. The anhydrous metal can be removed by dissolving the metal in an anhydrous solution or, s ometimes, by heating it.Oxidants can also be used in an organic chemistry laboratory. The two common oxidants used in an organic chemistry laboratory are the alkali metals and the polyoxides. Polyoxides oxidize slowly to the reduced form. Alkali metals oxidize very quickly to the reduced form. Polyoxides also can be used to bind the reduced form of polycarbonate.

What is the STEAM Movement

What is the STEAM Movement In recent years, there has been an increasing focus on STEM subjects Science, Technology, Engineering, and Math. Here are some great tips to help succeed in science and engineering. This emphasis is accompanied with the belief that these four subjects should be prioritized in education to match rapid growth in these fields in the industry. Here are 4 benefits of STEM studies. There is evidence to show that while jobs in these areas are increasing, there are not enough individuals with sufficient education to meet the workplace demand. In fact, studies have shown that the United States has fallen behind in both interest and education in these areas. Thus, STEM programs have been receiving support at both the national and state level in order to increase student interest and success. What is STEAM? With innovation in mind, some educators are calling for an integration of the arts back into the curriculum. This movement changes STEM to STEAM, by adding a critical piece left out of the STEM subjects: Art. The STEAM movement seeks to add Art and Design as another education area that should be focused on, with the idea that innovation and creative thinking are gained by uniting art and design with science and technology. Here are some great reasons why the arts are crucial to education. Why should STEAM be implemented? While the arts may seem quite distinct from science and technology, proponents of the STEAM movement maintain that the two can, and should, be integrated. For one, they state that in our media-saturated culture, integrating the arts (specifically visual and media arts) will make STEM subjects more appealing to younger generations, thus sparking increased interest in these fields. Additionally, art and design are important, although sometimes overlooked, areas of expertise, especially in the field of technology. Even employers who are hiring students in traditional STEM fields can benefit from the STEAM movement and the addition of arts and design to the fields of science and technology. Several recent studies have shown that up to 95% of employers want to hire individuals who are innovative. Additionally, similar studies have shown that around 85% of employers are actively seeking creative people to hire, yet struggling to find them. Advocates of the STEAM movement believe that the arts lead to creativity, and that creativity in turn leads to innovation. Hence, by teaching students the arts and integrating art and design into the fields of science, students of technology, engineering, and mathematics can become more innovative thinkers within those fields. According to this program, the alliance of Art with STEM will help students become more creative, increase their employability, and be successful in needed industries.

If youre a college senior who wishes to enroll in business school this fall, at this point in the admissions process you have either submitted your applications during Round 1 or Round 2, or you are preparing your applications for Round 3 or Round 4 in March and April. For those of you who have completed your submissions, congratulations! All you have to do at the moment is wait for your schools decisions to arrive before you plan your next steps. For college seniors who are still working on MBA applications, there are a few steps you can take today to prepare for b-school, such as taking the GMAT or GRE and speaking with current MBAs and alumni. B-school step 1: take the GMAT or the GRE Most MBA programs require students to submit a GMAT or GRE score with their application. Check which exam your short-listed schools prefer, and if you have not done so already, take that exam. If either is accepted, sit for the exam you perform better on. Although you dont have much time, you shouldnt take either test without first preparing for it. Take a practice GRE and a practice GMAT, and see which one you feel more comfortable with. Then, register for your exam, create a study plan, and put in the work so that you can perform your best. [RELATED: Should I take the GMAT or GRE?] B-school step 2: visit your schools Many MBA programs offer similar core curriculums, but not all schools are the same. Each school you apply to wants to know why you are choosing them and why they should choose you. Learning about your schools in person will help you answer these questions when asked on your application and during your interview. Schedule a tour with the admissions office so that you can sample a class, meet professors, and speak with admissions officers. Being on campus in your potential MBA environment will help inform why you are applying to that particular program. [RELATED: 4 Ways to Prepare For Business School During Your Last Undergrad Semester] B-school step 3: speak with current MBAs and alumni Find other people who have already gone through the business school application process and connect with them. Luckily, you will already be meeting some of these people when you take your school tours. You can also connect with alumni from your current college or university who have gone on to attend business school after graduation. Ask them how the MBA experience was for them.

The Best way to Learn to write Hanzi

The Best way to Learn to write Hanzi Chinese script: learn to write the characters ChaptersEasy Chinese words and characters to learnWhat direction do you read and write in Chinese?How to memorize the way to write Chinese charactersHelpful tools to learn Chinese charactersBeautiful, exotic, mysterious…these adjectives aren’t describing a tropical vacation destination, I’m talking about the Chinese writing system!When we talk about Chinese characters, we aren’t talking about an alphabet like we use in English. The Chinese system of writing is totally different from English, Spanish, or even Russian.Whether you’ve just begun Mandarin lessons, or are in intermediate or advanced Chinese classes, learning to write the hanzi can be a difficult challenge and it’s hard to find good learning methods to do it.Here we’ll talk you through a few of our top tips for learning to write in Chinese, and how to memorize and read Chinese characters.Another example is the character ? (ròu, meat)   and ? (Yú, which is the symbol for fish), so when you see ?? (niurou, bee f) at a restaurant, you can deduct that that symbol indicates some form of meat and not fish.Finally, thanks to the character ? (Zhàn), students will be able to get around on public transport in China.You should note that it’s necessary to practice writing and identifying your first 100 characters regularly in order to properly memorize them and move ahead in your language studies.We also have some tips for how to learn to write in Chinese.What direction do you read and write in Chinese?In China, last names are passed down the paternal line over millenniaThe People’s Republic of China followed the example of Japan and Singapore and completely did away with their traditional way of writing in 1956. This change followed an increase in Western influence in Asia and was meant to make the writing system easier to learn and more regular.Therefore, in mainland China if you’re at a Chinese language school or taking classes at the Confucius Institute it’s normal to learn to write Ch inese in a Western style - that is, horizontally, going from left to right.It’s the way you’ll see Chinese script in newspapers, magazines, and books as you go about your day to day life.Traditional writing is then relegated to the level of good taste, savoir-vive, and linguistic skills.Often you’ll see vertical writing (from high to low, and right to left), often without any punctuation, in greeting cards or handwritten letters that you write to your oldest family members.Esthetically, Chinese calligraphy also often takes the form of classical writing on shop signs.You’ll also see writing going from high to low on the outside of ancient monuments, in temples, and on the signs of many restaurants. It can often cause some funny stories of confusion, so it’s worth keeping in mind this possibility if you’re planning a trip to China and taking a semester of Chinese classes before you head abroad.Although rare, people do sometimes have trouble reading the written characters, and it’s something you’ll have to get used to if you’re planning to live in China. The key thing is to remember that there are no spaces between words like in Romance and Germanic languages, and the meanings of some words need to be inferred by context.Expats and native Chinese speakers alike can agree on one thing - it’s sometimes hard to tell in which direction you’re meant to be reading the characters. In Taiwan and Hong Kong, newspapers are still written vertically, and you can sometimes see characters written:from left to right, in the opposite direction that was instituted in the 1950s to simplify the Chinese language.from top to bottom like Chinese was traditionally written until the first half of the 20th century.And sometimes the two systems are mixed together, which can make the writing impossible to read for anyone born after Chinese language reform.Learn more about writing in Chinese with this glossary...How to memorize the way to write Chinese charactersIs the re a way to wish someone Happy New Year in Chinese without making reference to money?“A man’s life isn’t long enough to learn all of the characters.”This Chinese proverb can give you some indication of the mammoth task you’re taking on in memorizing Chinese characters.There’re an estimated 56,000 hanzis ?? (Chinese characters)! It would take more than an entire lifespan - at least if immortality hasn’t been invented yet - to learn every last Chinese character.Chinese language centers often emphasize the order in which you make the strokes when writing in order to teach the hanzis. This way of learning can often seem like memorization, but it’s actually quite logical. The repetitive strokes register in your brain just like any other form of writing, same as the way you learned to write in English.When you first start off writing Chinese characters, it’s best to start with strokes that start from the left before moving on to ones that are on the right. That way you†™re learning in the same direction as English writing.Then, for the rare times when the student is asked to write from high to low, the order is the same:Always start writing the strokes above before moving on to those below, same as you would in English.Then, following basic logic, you should always fill the square or outline before closing it. It’s common sense that you’d need to draw the character first before drawing an outline around it.What’s more, if you’re drawing a complex character, you should do the horizontal strokes before the vertical ones.Finally, some words made up of two or more characters should be written from right to left. The word ‘hello’ is a good example of this.You’ll normally learn all of these rules for writing script in your Mandarin language classes, and they’ll help you begin to make sense of the bewildering world of Hanzi. But of course, there are lots of other methods for writing Chinese characters too, and there’s no one way to do i t.In any case, it doesn’t matter so much which way you learn the Chinese characters, the key thing is that although learning the hanzi may seem like an impossible task, it’s totally doable.Learn more about writing Chinese Hanzi...Helpful tools to learn Chinese charactersHelpful websites to learn the hanziomniglotThis helpful online encyclopedia of different languages offers some great resources and useful links to other websites, as well as an app for learning the most common Chinese characters, available on Android and iPhone.Online apps for learning Mandarin Chineseskritter.comAvailable as an app on the iPhone, or online, this mobile app makes it easy for you to learn and study Chinese characters and is designed to do so in a way that will keep student’s motivated and encouraged.Following the precise directions provided, the user is invited to trace the character out, stroke by stroke, in the right order.

Living With Roommates What Introverts Should Know - Introvert Whisperer

Introvert Whisperer / Living With Roommates What Introverts Should Know - Introvert Whisperer Living With Roommates: What Introverts Should Know Kayla Matthews April 16, 2019 Communication No responses Go to top Like most introverts, I was intimated by the thought of going off to college and living with roommates for the first time. It was a gamble to see who I’d end up with and if we would get along. There were good days and bad days, but nonetheless, I discovered a lot along the way. Avoid some of my mishaps by learning how you can find the perfect roommate and what to do if you end up with a bad one. How to Find the Perfect Roommate Some colleges and apartment complexes allow you to choose your own roommate. If you have the option, take it. There’s plenty you can do to find someone compatible. 1. Look for an Introvert About 80 percent of people believe opposites attract, but science has proven it’s a myth. If you’re an introvert, look for someone that shares similar routines, such as craving alone time or preferring to listen over talking. 2. Share Common Ground Having common ground, no matter what it is â€" your college major, a hobby, a favorite movie â€" is an excellent foundation for a relationship. Finding a roommate who shares your goals, such as maintaining a 4.0 GPA, can even provide a support network for achieving them â€" something proven to benefit both your physical and mental health. 3. Ask About Tidiness One common point of contention between roommates is tidiness. Some may not mind a little mess around the apartment or dorm while others require spotlessness. Personally, I don’t mind letting a dirty dish or two sit for a day. No matter your preferences, look for a roommate who shares a similar mindset. How to Deal With a Bad Roommate Unfortunately, you don’t always have the option to choose your roommate. While you can avoid the dorms and rent your own apartment, sometimes you have to deal with a bad roomie. Luckily, there are steps you can take to make your experience a little easier: 1. Implement House Rules You and your roommate don’t have to be friends â€" you don’t even have to get along. Instead of getting mad when you and your roommate clash, be proactive and talk about rules you want to establish when you move in. From turning the music down after a particular time to cleaning up after meals, house rules can keep a bad roommate accountable and make your life less stressful. 2. Find an Outside Spot Sometimes there’s no way to fix a bad relationship. If you can’t get along with your roommate and can’t find a path to compromise, find an outside spot where you can regain your sanity. Some people enjoying spending time at their favorite cafe or coffee shop, taking a book or computer along. When the weather is warm, I like to escape roommates by walking to the park or going on a bike ride. 3. Ask For Help Bad roommates come on a spectrum, meaning some are worse than others. If you find yourself living with a roommate you cannot tolerate â€" maybe they refuse to stop throwing parties or you’ve discovered they’re selling drugs â€" ask for help. When the situation becomes too much to handle, there are people you can reach out to for guidance. In college, that might mean discussing things with your RA. If you’re renting an apartment, you could talk to the landlord or property manager. Living With a Roommate If you’re lucky, you’ll find the ideal roommate that can blossom into a friend. Just keep in mind that living with any roommate can have its challenges. While you cant always pick who you live with, there’s still plenty you can do to save your sanity and make life easier.

How is the SAT Scored

How is the SAT Scored The SAT is a standardized exam utilized by the majority of colleges and universities to assist in admissions decisions. Because the test is standardized, schools can roughly compare the abilities of all applicants based on their SAT results. [RELATED: What is an Average SAT Score?] A prospective students overall SAT score is the combination of results earned in three categoriesCritical Reading, Math, and Writing. Scores currently range from 600-2400, though the SAT will return to a scale of 1600in the spring of 2016, when the College Board releases its revision of the exam. View our past postfor section-specific changes. How is my score calculated? Final scores are calculated in the following manner: each correct multiple-choice answer is worth a maximum of one point. One-fourth of a point is deducted for an incorrect answer. (Beginning in 2016, the guessing penalty will no longer exist.) Omitted questions will neither help nor hurt the overall scoreno points are awarded or deducted. Certain math problems are scored differently. Questions that require the student to perform calculations and record a final response are scored on a point-no point basis. If the student's answer is correct, one point is awarded. If the response is incorrect, no point is awarded. There are no deductions on problems of this format. Here are five great SAT test prep tips. How is my essay assessed? The essay, which will become optional on the new SAT, is also marked in a different manner than multiple-choice questions. The Writing portion of the SAT includes an essay element that is given a score of 1-6 by two separate readers, for a maximum of 12 (unwritten essays will receive a score of 0). Readers are education professionals who grade each response based on the level of quality in a number of areas. These include: demonstrated critical thinking, a developed point of view with a clear focus and organization throughout, the appropriateness and quality of examples and vocabulary, overall flow and the rhythm of sentence structure, and grammar and mechanics. You may also want toutilize aprep bookto help you prepare. What is equating? What is percentile rank? When the raw scores for all three sections (Critical Reading, Math, and Writing) are obtained, they are each converted to a result between 200 and 800. This is known as equating. After raw scores are converted into what are now referred to as the calculated scores, they are used to compare the student's performance with the performance of other individuals. This percentile rank is what schools pay close attention to, because it describes how well a student compares to all other individuals who have completed the SAT at that time.
