  A: As described in the text, negatively charged electrons are produced by a reaction that reduces the positively charged lead anode. The reducing agent, in turn, is oxidized by this reaction. These electrons travel through the wire to the negatively charged cathode, where they react with the sulfuric acid oxidizer and reduce it, forming lead sulfate. In a car battery, the anode is normally indicated by a red mark. A: In an oxidation reaction, an oxidizing agent gains electrons from a reducing agent. By contributing electrons, the reducing agent reduces, or makes more negative, the charge on the oxidizer. In the car battery, reduction of the positively charged anode provides electrons, which then flow to the cathode, where an oxidation takes place. In an oxidation, an oxidizing agent increases makes more positive the charge on a reducer. In this way, the extra electrons in the negatively charged cathode are neutralized by the surrounding oxidizing agent.

  I'll also walk you through the answers to give you an idea of how to approach and solve them. Sample Multiple-Choice Question Many questions on the AP Chemistry exam ask you to make predictions about chemical properties or reactions based on data like this. In this case, the answer is A. The coulombic attractions are weaker in NaCl than they are in NaF because the ionic radius of F- is smaller than that of Cl-. The attraction between molecules will be greater in NaF, and the bonds will be harder to break. Sample Short Free-Response Question In this question, part a requires an understanding of why or why not reactions might occur between molecules. First, you need to explain how collision energy affects whether two molecules will react with each other. Only collisions with enough energy to overcome the activation energy barrier typically represented by the variable Ea will reach the transition state and break the F-F bond. Next, you need to identify one other factor besides collision energy that influences the likelihood of a reaction between two colliding molecules.

• CHM Quizzes And Exams

  You could say that in order for a collision to be successful, the molecules must have the correct orientation. You would need to mention the specific bonds being formed and broken. Only molecules with the correct orientation can start to form the N-F bond and break the F-F bond. The molecules have to contact each other in very specific places for the transition to take place. Part b is about rate laws, and the first part is pretty straightforward. You then need to explain why you made your choice to get the last point on this question. The second rate law is the correct answer because Step I is the slower, rate-determining step in the reaction mechanism. Step I is an elementary reaction, so its rate law comes from the stoichiometry of the reaction molecules, NO2 and F2. Sample Long Free-Response Question In part a of this question, you're asked to write two net-ionic equations.

• CHEM Test Bank Of Quizzes And Exams

  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.

  https://amie.nbcafe.in/phpbb/viewtopic.php?f=2&t=2094

• Practice Quizzes

  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?

Chemistry builds on itself, so if you don't get the fundamental reason your answer was correct or incorrect, you could be in for a whole mess of trouble in the future. 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.

  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.
