    Writing balanced equations based on experimental scenarios is an important skill for the test. In part b, you need an understanding of what causes electrical conductivity in chemical substances and why the conductivity decreases at first in the situation described. Part c requires some attention to detail in unit conversion as well as a logical assessment of the information you're given. Molarity is moles per liter, so the question is how many moles of Ba OH 2 were there per liter in the original solution without the added H2SO4. Since the conductivity starts going back up after 30 ml of H2SO4 are added, that means that at that point the number of moles of H2SO4 is equal to the number of moles of BaOH2 in the original solution.

  • For Students

    We can calculate that 30 mL of 0. There should be the same number of moles of BaOH2 in the original solution, so we can divide 0. The solubility product constant equals the product of the number of ions of each component of the precipitate. In this case, you would need to mention the common ion effect and the fact that if you add sulfate ions to an equilibrium reaction involving other sulfate ions, the reaction will consume the added ions to reach a new equilibrium. Equilibrium must be reached. Transition from doing As you can see, the questions on the AP Chemistry test range from short and sweet to long and moderately evil. An important thread that runs through all of them is that you need to know basic background information about why certain substances act the way they do. For example, why do some substances have higher boiling points than others?

    For example, you might have memorized that a certain molecular compound has a higher boiling point than another, but that doesn't mean you necessarily know why this is the case. Make sure you always know why certain properties occur based on molecular and atomic structure so that you can justify your answers and adapt your knowledge to a variety of scenarios. Even though you'll get a formula sheet, it's going to be much easier to get through the questions if you don't have to keep consulting it. For each formula, make sure you know the types of questions it will help you answer and how else it could come into play on the test. You'll see many questions on the exam that deal with lab scenarios, and it's much easier to understand these types of questions if you're somewhat familiar with the setup. It's crucial to understand why you got the results you did for each lab and to be able to connect them to facts about chemical reactions and properties of different substances.

    This is kind of scary for some people, but it shouldn't be a big obstacle if you're well prepared. You'll save yourself a lot of time if you practice doing multiple-choice questions and estimating logical answers without going through long calculations. The more familiar you are with the mechanics of chemical reactions, the easier it'll be to estimate the answers to these problems. All free-response questions include sample answers as well as commentary that explains what is particularly good and not so good about the response. Since the material is complicated and there are a lot of different things you need to know how to do, a review book can help ground you and give you a better handle on how to structure your review overall. You'll also get a lot of additional practice problems and answer explanations.

    I have long felt that students study more thoroughly for free response exams than they do for strictly multiple choice exams. I remember that I did when I was a student. In large classes, it is difficult to have all work-out problems and essays on exams without an army of graders, so I have compromised. At the end of the exam, the proctors and I collect everything from the students. As soon as the exam is over, I go to my office, give the multiple choice part of the exam back to the students with an answer key. We used to hand out answer keys as the students left, but due to cell phones, pagers and other communication devices, I have changed my policy.

    The multiple choice part is graded by machine that day, and I usually put up the scores on WebCT that night. Students can pick up their multiple choice and an answer strip by my office directly following the exam. I have one grader who grades all of the free response part of the exams over about 5 days. All my exams are given on Tuesdays. The grader returns half to me on Friday and the rest by Monday morning. I then go over all the exams a second time to catch the small grading errors that always occur. The free response parts are handed back to the students on Tuesday. Between the two of us, we have very few complaints.

    To prevent cheating, I make two forms of every test, one is copied onto green paper, the other onto yellow paper. The forms have different but similar questions in a different order. It is easy to see if people with the same exam are sitting next to each other. We also provide them with scanning sheets. They do not bring their own to the exam. We collect the scanning sheets in class to replenish the ones we use for exams. The exams and scanning sheet are placed into exam envelopes printed with the periodic table and other information. Several years ago, I learned a unique, simple but effective way of giving partial credit. Many times students can eliminate three possible answers, leaving them with two.

    Anne Marie Helmenstine, Ph. Updated July 03, A gas is a state of matter with no defined shape or volume. Gases have their own unique behavior depending on a variety of variables, such as temperature, pressure, and volume. While each gas is different, all gases act in a similar matter. This study guide highlights the concepts and laws dealing with the chemistry of gases. Properties of a Gas Gas Balloon. Paul Taylor, Getty Images A gas is a state of matter. The particles that make up a gas can range from individual atoms to complex molecules. Some other general information involving gases: Gases assume the shape and volume of their container. Gases have lower densities than their solid or liquid phases. Gases are more easily compressed than their solid or liquid phases. Gases will mix completely and evenly when confined to the same volume. These gases are known as the noble gases. Elements that are gases at room temperature and normal pressure are all nonmetals.

    Pressure Pressure is a measure of the amount of force per unit area. The pressure of a gas is the amount of force the gas exerts on a surface within its volume. Gases with high pressure exert more force than gas with low pressure. The SI unit of pressure is the pascal Symbol Pa. The pascal is equal to the force of 1 newton per square meter. This unit is not very useful when dealing with gases in real world conditions, but it is a standard that can be measured and reproduced. Many other pressure units have developed over time, mostly dealing with the gas we're most familiar with: air. The problem with air, the pressure isn't constant. Air pressure depends on the altitude above sea-level and many other factors. Many units for pressure were originally based on an average air pressure at sea-level, but have become standardized.

    Temperature Temperature is a property of matter related to the amount of energy of the component particles. Several temperature scales have been developed to measure this amount of energy, but the SI standard scale is the Kelvin temperature scale. The Kelvin scale is an absolute temperature scale and used in nearly all gas calculations.

    It is important when working with gas problems to convert the temperature readings to Kelvin. STP is commonly used in calculations involved with the density of gases or in other cases involving standard state conditions. At STP, a mole of an ideal gas will occupy a volume of Dalton's Law of Partial Pressures Dalton's law states the total pressure of a mixture of gases is equal to the sum of all the individual pressures of the component gases alone. The individual pressure of the component gas is known as the partial pressure of the gas. Avogadro's Gas Law Avogadro's law states the volume of a gas is directly proportional to the number of moles of gas when pressure and temperature remain constant. Basically: Gas has volume. Add more gas, gas takes up more volume if pressure and temperature do not change.
