Organic Chemistry Teachers Knowledge Of The Periodic Table

Organic Chemistry Teacher's Knowledge Of The Periodic TableThere are certain table properties that every organic chemistry tutor should be aware of, and one of them is that the hydrocarbon molecules found in gasoline or propane, for example, are not actually present in nature. When a student asks, 'What is the difference between diesel and gasoline?'One organic chemistry tutor recently had a student who insisted that gasoline was actually petrol, and that the gas that we see coming out of the tailpipe was actually fossil fuel, which was derived from natural gas, which was derived from natural gas by having water and oil mix together to form methane gas. But how did he come to this conclusion? He had a quick look at the periodic table and was able to demonstrate it to his student.Gasoline is a hydrocarbon molecule, which consists of a carbon and two hydrogen atoms bonded together in a single, double bond. Ethanol, a lower alcohol, is made from gasoline by using ethanol as a solvent. E thanol is also made from propane by combining carbon dioxide with hydrogen. The molecule you see in your car's gas tank, known as methanol, is composed of gasoline and hydrogen.For the purpose of this article, let's take a look at what constitutes petrol, and what constitutes methanol, and the organic chemistry tutor can go into more detail on that subject. However, in general, petrol is simply the term used for the combination of a carbon and two hydrogen atoms, while methanol is composed of three carbon atoms and two hydrogen atoms. So while it can be further broken down into tertiary and secondary types, the key property is still the four-carbon unit, or carbonyl group.When it comes to petrol, the organic chemistry tutor would find that it is composed of carbon, hydrogen, oxygen, nitrogen, sulfur, phosphorus, and sometimes nickel, platinum, or chrome. Therefore, it is quite important to know the properties of a carbon molecule, and what are its molecular weights, and carbon chain lengths. Additionally, if your student wants to study the lightest forms of carbon, it will be useful to note that the C atom is the lightest, and the O atom is the heaviest.In addition to knowing these properties, the organic chemistry tutor must also be familiar with the bonding properties of the hydrogen atoms. When they are bonded to other atoms, the carbon becomes less stable, which is why methyl groups are typically used to help stabilize it. The use of an ethyl group will help solidify the carbon, making it more stable, and consequently, the molecule will become more stable in the presence of an acid.The final table property that your organic chemistry tutor should be aware of is that of what occurs when two carbon molecules are placed together. It may sound a bit complex, but it is important to understand that this bonding can be very stable, and because of this, the normal cyclic compounds of carbon, such as dichloromethane and ethyl chloride, occur naturally.These table p roperties are all well and good, but the organic chemistry tutor should be knowledgeable enough to teach his students that they should never be confused by the types of compounds that they encounter during their course. It is really up to them to determine which is the right one for the chemical formula that they want to work with.

Teaching in China on a tourist visa Can it be done

Teaching in China on a tourist visa Can it be done In the past, it was common practice for English teachers to arrive in China on a tourist visa and start working, while waiting for their employers to transition them to the correct Z visa status. However, teaching English in China on a tourist visa (otherwise known as an L visa) is a route we don’t recommend here at Teach Away, for reasons we’ll dive deeper into below. But, essentially, it boils down to this: A Z visa (also commonly referrred to as a Foreign Expert Permit) is what sets you up to obtaining the two key documents you need to continue working legally in any province in China - those all-important residence and work permits. That’s why we always recommend you obtain your Z visa before arriving in the country. That way, you know your employer is actually legally allowed to employ foreign teachers (which they need a license to do) before you start packing your bags for the big move. Recommended reading: Do you really need a visa to teach English abroad? Requirements for teaching English in China [Video] Candidates applying for a Z visa to teach English in China should: Hold a bachelor’s degree Be a native English speaker Have two years of teaching experience/teaching certification/TEFL certification Note: Z visa applicants are also subject to the same retirement ages as Chinese workers, so if you’re a woman over the age of 60 or a man over the age of 55, then age restrictions will apply. But lots of commenters on Reddit claim they’re teaching English in China on a tourist visa? It can’t be that big of a deal! The internet is also chock full of horror stories of expat teachers being arrested for working illegally on a tourist visa in China. And the consequences of being caught working illegally in China can be pretty dire. You could face penalties ranging in severity from fines to jail time or deportation if you’re teaching under a tourist visa. Trust us, not only have the Chinese government been tightening up their visa regulations in recent years - they’re also raiding language schools falling afoul of the law and detaining foreign teachers working without the right work permit. While these occurrences are, thankfully, becoming less and less frequent as the Chinese ESL industry continues to clean up its act, the risks you take by teaching under a tourist visa are still very real. That’s why, if your school is unable to obtain a Z visa for you before your departure, we advise you to seriously consider whether this is an offer you should be pursuing. Any reputable, well-established school will not pressure you to teach English “under the table”. They know better than most that this is a big no no with the Chinese authorities. Sign up to Teach Away today for access to the latest teaching jobs around the world. By agreeing to teach on a tourist visa, you’re highly vulnerable to exploitation by unscrupulous employers or unregulated agencies. Something to be aware of is the fact that many English teachers at schools in China actually have their contracts handled by for-profit, third-party hiring agencies, rather than by the schools directly. These agencies earn a commission for every teacher they place. As a result, some will go so far as to offer contracts to non-native English speaking teachers, who they know will never qualify for Z visa status. These agencies may have zero intention of ever completing the right documents for you, essentially leaving you stranded as an illegal worker in China. And open to exploitation. We’ve heard of ESL teachers placed in China under tourist visas, who not only had their wages skimmed but were forced to live in unsanitary accommodation and work extended hours without days off. Read this: How to spot common ESL job scams Can’t I just convert my L visa to a Z visa when I’m living in China? As we talked about above, if your employer is urging you to work on an L visa and convert to a Z visa at a later date, then you should know that by doing so, you’re essentially beaking the law. Plus, when you apply for a tourist visa for China, you’ll need to show proof of hotel bookings for the duration of your stay and your return flight home within the three-month timeframe permitted. Technically speaking, you could consider having an extended holiday in Asia while you’re waiting for your Z visa to be sorted out. So long as you’re willing to take on the expense of returning home or flying to Hong Kong so you can get that Z visa, that is. And that’s because: Z visas can also only be issued outside of China, in either your home country or Hong Kong. This means that, more than likely, you’ll be faced with an expensive trip back to your home county or Hong Kong so you can then re-enter under the right work permit status - an additional cost that your employer might not be willing to be on the hook for. And if your employer is dragging their heels on getting your Z visa organized once you’ve arrived, then you need to ask some serious questions about their legitimacy. So, to recap: You can’t legally teach English in China on anything other than a Z visa (that includes L and F visas). You shouldn’t move to China to teach on a tourist visa with the promise of bveing transferred to a legal working visa at a later date.

What is an Average MCAT Score

What is an Average MCAT Score The concept of an average MCAT score has been somewhat nebulous since the AAMCs reformatting of the MCAT in 2015. Previously, the average MCAT score across medical school applicants was 25, and the average MCAT score of admitted applicants to medical school was around 31. Since the test was redone and a new scoring scale was constructed, the average MCAT score across medical school applicants is approximately 500. However, it is important to distinguish between the AAMCs average MCAT score and the average MCAT scores of students who matriculate at individual schools. Here are some things to know when thinking about average MCAT scores: What is the average MCAT score for admitted applicants to MD (allopathic) programs? According to the AAMC, the average overall MCAT score for matriculants into U.S. MD programs is 508.7over eight points higher than what the AAMC deems acceptable for admission. A 508 puts the test-taker in the 79th percentile of all fellow test-takers, meaning that admission into medical school may be contingent upon outperforming the majority of pre-med students taking the test alongside you. [RELATED: What is it Like to Attend Johns Hopkins University School of Medicine?] What are the average MCAT section breakdown scores of admitted applicants to MD programs? Each of the four sections has an average score of around 127 for admitted applicants. The lowest-scoring section tends to be Critical Analysis and Reasoning Skills (126.7 average), and the highest is a tie at 127.4 between: Biological and Biochemical Foundations of Living Systems Chemical and Physical Foundations of Biological Systems Although the AAMC delineates a score of 125 in each section to demonstrate sufficient readiness for medical school, it is clear that medical schools use higher section scores for their admissions standards. What is the average MCAT score of DO (osteopathic) program applicants? According to AACOMAS, the average DO applicant in 2016 had an MCAT score of 499.3 (median 500). However, the average DO program matriculant had an MCAT score of 502.1 (around the 60% percentile of test-takers). Similar to their MD program counterparts, DO programs tend to accept applicants with higher MCAT scores than the benchmark of 500 set forth by the AAMC. What are the average MCAT section breakdown scores of admitted DO applicants? Admitted DO applicants have an average score of around 125-125 on all four subsections of the MCAT. The Biological and Biochemical Foundations of Living Systems and the Psychological, Social, and Biological Foundation of Behavior sections tend to have higher scores, with averages around 125.7. The Chemical and Physical Foundations of Biological Systems has an average score of 125.5, and the Critical Analysis and Reasoning Skills section has an average score of 125.1. So, what average MCAT score should you aim for? Admission into medical school is based upon much more than your MCAT score, but meeting the average benchmarks of programs in which you are interested may cause admissions committees to view your application more favorably. If you are applying to MD programs, striving for an MCAT score of 508 with a minimum score of 127 in each subsection is a reasonable goal. If you are considering DO programs, aiming for a 502 with a minimum score of 125 in each subsection is also reasonable. However, more selective programs may require higher-than-average scores of their admitted applicants, and it is important to consult sources like MSAR in order to gauge where your own testing goals should be. If your scores dont stack up against those of a schools recently admitted class, your chances of admission to that school may be reduced. Start incorporating MCAT prep into your daily routine and make it your goal to apply to medical school with a score that gets you noticed. Any topics you want to know more about? Let us know!

Studying for the SAT Online SAT Prep Online Tutoring Tutorpace

Studying for the SAT Online SAT Prep Online Tutoring Tutorpace Many students find the SAT exam very difficult and question themselves whether they can get a good score on it. It is true that SAT exam is little hard, but it should be remembered that the exam is designed for high school students only. So it is surely possible to get a very good score on SAT provided the student learns and prepares the concepts accordingly. The SAT test paper consists of 3 important sections: Critical Reading, Mathematics, and Writing. The main purpose of the SAT is to examine the students logical and conceptual knowledge. It is important to remember that little tricky concepts can be understood only if the students basic knowledge is strong. Therefore instead of practicing too many hard questions, it is beneficial if students first start learning from the basic topics. In order to get a good score in the Reading section, students need to understand the proper usage of words in a sentence. This section contains sentence completion and passage based questions. For the reading comprehension questions, students must first understand the main idea of the author in the passage and should then answer the questions. In the Mathematics section, students are provided with the commonly used formulas during the exam but it is the students duty to learn how and when to use the formulas appropriately. In the Writing section, students must focus on their point of opinion on the given topic and should support their opinion accordingly to write a good meaningful essay.

Sum of Normal Distributions

Sum of Normal Distributions A normal distribution is a probability distribution which can be clearly represented using a bell curve. A standard normal distribution is also a normal distribution, however the mean of such a distribution is 0 and the standard deviation is 1. A bell curve, also known as the normal distribution curve is a graph which depends on factors such as the mean and the standard deviation of set of real numbers. The z-score value of normal distribution is given by a formula which depends on the mean standard deviation and the normal random x value. Example 1: For a set of random variables, given the normal random variable to be equal to 15. If the mean of the given set is 5 and the standard deviation is 2, then what is the standard score or the z-score? Given, x = normal random variable = 15 Mean, = 5 Standard deviation, = 2 The z-score = (x )/ This implies, z-score = (15 5)/ 2 = 10/2 = 5. Therefore, the standard z-score is 5. Example 2: For a set of random variables, given the normal random variable to be equal to 24. If the mean of the given set is 18 and the standard deviation is 3, then what is the standard score or the z-score? Given, x = normal random variable = 24 Mean, = 18 Standard deviation, = 3 The z-score = (x )/ This implies, z-score = (24 18)/ 3 = 6/3 = 2. Therefore, the standard z-score is 2.
