Synthesis Practice Problems in Organic Chemistry

Synthesis Practice Problems in Organic ChemistryOrganic chemistry is composed of synthetic and natural sciences. Synthesis is the art of combining two or more substances into a single compound. Synthesis is used to make compounds that are useful to man. It can be done using acids, bases, bases and alkylating agents.There are many ways to synthesize compounds in organic chemistry. Inorganic Chemistry is the branch of organic chemistry dealing with the two chemical compounds of carbon and hydrogen, polymers and polymer polymers.There are many different ways to combine a compound. The chemical reactions that take place when one substance interacts with another one can vary from one reaction to another.Common examples of synthetic reactions are those which will form gaseous materials like air, smoke, gas, steam, flame, etc. Another example is adding salt to an acid. Lastly, if you are in doubt as to what an addition does, it is best to ask an expert in chemistry.One of the most common ch emical reaction that takes place is from nitrous oxide to nitrogen. This is commonly known as oxidation. Oxidation can be done in two ways, by addition of oxygen and by reduction.Forming hydrogen is not as simple as it sounds, it is necessary to put a substance that will react with the water molecule. Another method would be to create a chemical compound by breaking up a known substance.There are a number of ways in which to obtain this compound that would then result in the efficient methods of making it. Synthesis is considered one of the most efficient means of using the lab for science. There are many aspects that you will need to know when creating a compound or an effective solvent.If there are substances that can help you get the desired results you should study this very carefully. Finally, it is not advisable to spend a lot of money on experiment. A much more cost effective way to obtain the same results would be to look for a specialist lab that can handle such problems an d provide the essential knowledge to its customers.

Why Advancing During the Holidays is Important

Why Advancing During the Holidays is Important Why Advancing During the Holidays is Important It’s official! We’re approaching the thick of the holiday season â€" otherwise known as the most wonderful time of year for many adults and children alike. As millions nationwide buckle up for travel to visit family and friends near and far, there are a few things all parents should keep in mind when it comes to kids and learning during the holiday school break. While all children should enjoy this festive time of year, a break from school doesn’t have to mean a break from learning. Continuing structured learning during the holiday break can contribute towards a successful school year. This means keeping up with Kumon assignments during the holiday season. Here are a couple of reasons why this is so important to maintaining progress. Daily practice goes a long way. The key to success in Kumon is continuity of practice. During school breaks, children typically have less thinking to do and more unstructured time. Continuing Kumon study during the holiday break promotes educational development and an element of year-round stability in your child’s academic life. Many experienced parents will say sticking with Kumon year-round is the secret ingredient for substantial academic gains in the school year. A steady routine helps keep kids on track. Maintaining a steady routine with Kumon even during the holiday break will make returning to a normal schedule seamless. Consider how motivated and great we feel when we work out regularly. After taking a few weeks off from the gym, getting back into our routine often becomes difficult. The same thing happens with academic habits. Our motivation stays high when we do not fall out of our routine. Significant schedule changes and different surroundings can make consistent practice a challenge for students. Falling out of the daily routine becomes easy, and trying to catch up later becomes difficult. When planning for schedule changes, and particularly when taking trips, it’s important also to plan when children will complete their school-assigned homework and Kumon assignments too. What works for many families is for children to complete the Kumon worksheets first thing in the morning before the hustle and bustle of the day gets into full swing. Sticking with the routine helps students continue their progress, and it makes the transition back to school after the new year a smooth process.

Tips to Learn Portuguese

Tips to Learn Portuguese Language Learning Tips for Portuguese Beginners ChaptersWhy You Should Learn to Speak PortugueseHow Can You Choose the Right Portuguese Lessons?Where Should You Look for Your Private Portuguese Teacher?The Price of a Portuguese ClassLearning to Speak Portuguese: Don't Forget to Study in Between LessonsPortuguese, in all of its versions, is spoken by more than 200 million people around the world, making them  the 7th most spoken language globally in terms of native speakers. It is  behind Mandarin, Hindi, English, Spanish, Arabic, and Malay.Portuguese uses the Latin alphabet, just as many other European languages do. Therefore, it is often thought to be an easier language to grasp than if you want to learn Russian, Arabic, or Korean for example.It doesn't matter if you want to be completely fluent, or just have a conversational level, the most effective processes for studying Portuguese are often the same as for any second language. This means that if you want to learn Italian, Spanish, or German, the best way to go about it doesn' t necessarily change that much.Nevertheless, there is not one perfect teaching method for everyone. Some will prefer strong discipline while others will be keen to rely on more relaxed methods to teach them.Throughout this article we will look at everything that you need to know in order to learn Portuguese in order to communicate with a native speaker in Portugal, Brazil, and even certain countries in Africa. Aside from that, it will be useful when you go for  Portuguese London shopping.Our platform is full of excellent Portuguese teachers who are waiting for you!The Price of a Portuguese ClassThe price of a Portuguese class varies enormously according to many criteria. For those who want to learn Portuguese on their own, without outside help, it is often possible to learn completely free of charge. But you can bet on slow progression and acquiring the language in a less safe way. For one, there is no one to ask about any doubts that you have.We believe that this method of learning can be a complement to enriching your linguistic skills, but that on its own, it will not make you bilingual, if that is your goal.There are several tips to note when it comes to the cost of a Portuguese class:Web-based courses tend to be cheaper, as do group classes (pooling costs),Courses provided by natives are on average more expensive. It is sometimes by paying the price of a native that we can learn more about Brazilian culture, or the history of Portuguese civilization,Great differences in price exist depending on the geographical zone: large cities remain more expensive than smaller urban areas due to transport being more expensive and there being higher living costs,On the outskirts of big cities, tutors generally give classes at lower prices.Learning to Speak Portuguese: Don't Forget to Study in Between LessonsDon't forget that you need to study between Portuguese lessons in order to give yourself the best chance of being successful. There are very effective methods when it comes the memorization process. From your first lessons in Portuguese, you will have to become familiar with your learning method of choice if you want to speak the language like a pro.Obviously you will need personal motivation in order to succeed in learning Portuguese, but you will also need to use of all the resources available to you to study in between lessons. If you don't study outside of your classes, you are more likely to forget what you have studied before the next lesson comes around.Many learning options exist, like systematically making notes  so that you don't get lost in the process of learning the language. To do this, the learner might want  to build a color code (ex: a certain color for a new word of the Portuguese vocabulary, a different color for an adjective or a pronoun etc...). The only rule will be to remain clear while noting the most useful information.Many applications also act as virtual teachers. These include Duolingo, which sets you learning goals , and Mosalingua, which introduces you to an innovative memory-based approach that will help you to revise knowledge when it is in the process of being forgotten. This methodology is based on scientific studies regarding  the forgetting curve. According to this approach, a notion, a word, or an idea must be reactivated intermittently in order to be permanently memorized.This student is despairing--but little does he know there are apps to help with that!Online solutions do not stop there and there are  many websites that will make it possible to study the basics of Portuguese for beginners, or more complex concepts for the more advanced student. Some sites even offer effective  pronunciation modules.Immerse yourself in the language and learn to speak Portuguese through Youtube tutorials, which are sometimes very detailed and helpful.Yes, in addition to more traditional studying methods such as textbooks, there are many solutions available to us. Choice is a luxury here, but be sure to use everything out there to increase your chances of success.In short:Having  learning objectives  will make it easier for your tutors to know what learning methods to use. For someone who just wants to learn and assimilate some Portuguese, the self-learning method can be a useful and effective approach. It will be more difficult for a learner who is looking for fluency in Portuguese.The important thing is to choose a tutor  with whom you feel confident and whom you can trust. The form of the learning is sometimes as important as the language itself (what you are learning).There are many ways to learn the language and they can be used in conjunction with each other (private tutor, group classes, applications to test your level or revise certain concepts, websites, forums to help to solve certain linguistic problems, etc.).In short, it's very easy to take Portuguese classes with a learning method available for every type of learner.

When Should I Apply to Medical School

When Should I Apply to Medical School Deciding toapplyto medical school can be stressful and time-consuming. However, with careful planning, you can successfully manage this processas well as your classes, extracurricular activities, MCAT prep, and social responsibilities. You must: meet with your schools pre-medical adviser, sit for the MCAT, request letters of recommendation (LORs), and complete the application itself. This consists of the American Medical College Application Service (AMCAS) system, secondary applications, and interviews. The below timeline references your junior year of college, and it assumes that you plan to attend medical school immediately after graduation. Create a calendar Print a month-by-month calendar on several sheets of paper, and annotate it with important deadlines. You may also wish to include proximity alerts, which remind you of upcoming dates. Place the calendar in a highly visible locationabove your computer is an excellent choice. Remember to print a physical calendar! While your deadlines will not change, you do not want to click or tap several times to view a date. Additionally, little feels as wonderful as crossing out a task that you have completed. You may also want to check out these tips on how to decide which medical school is right for you. Meet with your adviser in the fall Most schools have a pre-health, pre-medical, or pre-professional adviser. Advisers become extremely busy during the spring semester, so schedule an appointment with him or her in the early fall. If your adviser understands your situation, it will be much easier for him or her to answer a brief question for you in the spring. Ask for letters of recommendation in early spring Approach professors who know you well in one of two ways: if you had a pleasant experience with a professor, but you do not plan on continuing your interaction, ask for a letter of recommendation immediately after the class ends. If this is likely to be an ongoing relationship (i.e. a professor in a small department that concerns your major, or one with whom you will do research), ask between January and March. Recognize that professors are not always available. Is your favorite professor going on sabbatical? Inquire, and note their dates of availability on your calendar. Here are some great tips for asking for a medical school letter of recommendation. Sit for the MCAT and submit your application in late spring/early summer Complete the MCAT between April and June. This way, if you must retake it, you can devote one to three months to preparing. Be realistic about the amount of time you require to review, as well as whether you need an MCAT tutor. It is possible to improve your score, but it involves time and hard work. Certain programs utilize rolling admissions, so apply to medical school early! AMCAS opens during the first week of May. Submit your biographical information, coursework, letters of recommendation, personal statement, and test scores in June. Secondary applications are issued by individual medical schools. These require several short essays in response to specific prompts. Write down any deadlines associated with secondary applications on your calendar. Attend interviews and commit to a school in your senior year Certain programs grant interviews as early as August. However, most will do so in the fall and winter months. In general, schedule them as early as possible. Keep in mind that you may find it wise to begin with those schools that are not your first choice, in order to practice. Here is some great information on medical school interviewsthat you may find helpful. If you receive an acceptance letter, make your decision carefully. By mid-spring of your senior year, you must accept one medical schools offer. If you are waitlisted, notify the school of changes to your application (i.e. an improved MCAT score). As you may realize, there is a great deal to do, as well as a deceptively long time in which to do it. Applying to medical school early may improve your chance of success, so submit your materials in June. This is the first step in a lifetime of work that is not possible without excellent time management, so give yourself plenty of leeway, follow your handwritten schedule, and you will be surprised at how much less stressful this year can be.

Equivalence Point

Equivalence Point Equivalence Point The Equivalence point is also called as the stoichiometric point. In an acid base titration it is a point at which chemically equal quantities of acids and bases are mixed. In simple words its the point where the number of moles of acid is equal to the number of moles of the base. So when the acids and bases are mixed in the right proportions they can neutralize each other. Understanding Titration: The qualitative chemical analysis titration is a laboratory method which is used to find the concentration of an unknown quantity. In this method the titrant which is the known concentration of a solution is added to the analyte the solution with an unknown concentration until the reaction is completed. The equipment used for carrying out a titration is burette, clamp, conical flask, pipette and pH indicator (this depends on the type of reactants used.) Alkalimetry and Acidimetry: An acid-base titration is when quantitative analysis is used to find the concentration of the unknown acid or base. Mentioned below are the two types of acid base titrations. The acid-base titration which is used to determine the concentration of a basic substance is called as alkalimetry. The acid-base titration which is used to determine the concentration of an acidic substance is called as Aciditmetry. Depending on the type of acid base titration the pH indicator needs to be chosen. Mentioned below are the different methods used in determining the equivalence point. Use of pH indicators in a titration: The pH indicators are used to determine the equivalence point in a titration. This implies at equivalence point there is a change in color observed. A drop of the indicator is added in the beginning of the titration at the end point observing the color change the equivalence point can be approximated. Conductance: The ions present in the solution determine the conductivity of a given solution. There is a certain amount of conductivity during the starting of the reaction. After the titration occurs and the neutralization takes place there is a change in the conductivity. Therefore, by calculating the change in the conductivity the equivalence point can be approximated. Color change: During few reactions there is a noticeable change in the color of the solution at the equivalence point. This change can be observed even without adding any indicator. Precipitation: During a chemical reaction sometimes there is a precipitation occurring at the equivalence point. Precipitate is a solid residue formed as a result the titration. Calorimeter: The isothermal titration calorimeter is a used to determine the equivalence point of a titration. This instrument detects the heat produced or consumed during a reaction and the change in the heat can be used to approximate the equivalence point. Thermometric Titrimetry: As the name suggests, thermometric indicates the thermal change of a given chemical reaction. In this method the equivalence point is estimated by observing the rate of change of the temperature (that is the rise or fall of the temperature.) Spectroscopy: This is a very interesting method to estimate the equivalence point of a reaction. In this method the equivalence point is determined by the amount of light absorbed by the reactants and the products. Amperometry: This method is used for generally the redox reactions. In this method the equivalence point is estimated according the rate of change in the current. Equivalence point Vs end point in a titration: Though the names sound similar both equivalence point and the end point are different. The equivalence point is determined by the theoretical calculations by equating the number of moles of the titrant and the analyte in a reaction. The end point is whereas determined in the laboratory by observing the color change or the instruments. The ideal situation is when the equivalence point is very close to the end point in a titration. The most commonly used pH indicators are: The table below list the type of indicator and the color it holds in the acidic side and the basic side. Indicator Acidic side Basic side Methyl violet Yellow Violet Methyl Orange Red Yellow Methyl Red Red Yellow Litmus Red Blue Phenolphthalein Colorless Pink Bromothymol Blue Colorless Blue The pH rules for the formation of different kinds of solutions: A neutral solution is formed by the reaction of a strong acid and a strong base. (pH = 7) An acidic solution is formed by the reaction of strong acid and a weak base. (pH 7) A basic solution is formed by the reaction of weak acid and a strong base. (pH 7)
