Few of these offer complete tests in the same format as the real exam, but they do provide a large repository of practice questions mainly multiple-choice. These are great if you're looking for questions in specific topic areas or are studying early on in the year and want to avoid certain concepts that you haven't learned in class yet. Just be wary of using these resources too much in your studying, and make sure you supplement them with official College Board materials at regular intervals. Unofficial practice questions often lack many of the nuances of real test questions. In a lot of cases, they will test straightforward factual recall whereas on the real test you'll have to do more complex analyses of unfamiliar experimental scenarios.

SAT / ACT Prep Online Guides And Tips
How to Use AP Chemistry Practice Tests Practice tests are great study tools for AP tests, and they're especially helpful for a subject like Chemistry that involves a lot of calculations and experimental analysis. In the next couple of subsections, I'll tell you how to use practice tests throughout the school year to prepare for the AP Chemistry exam. First Semester: Using Practice Tests for Your Class It's not practical to take full practice tests during the first semester of AP Chemistry because you haven't covered enough of the course material yet. Focus on official free-response questions and unofficial topic-specific practice tests that address aspects of the curriculum that you've learned already. It's a great idea to start early and do consistent reviews so that your knowledge base remains strong throughout the year. Since chemistry is a subject that builds on the fundamental concepts learned in the first few months of class, it's vital that those early lessons are solidified in your memory.

This way, more complex material that you learn second semester won't fly over your head. You can also consider getting a prep book; most of them have practice questions organized by chapter for selective review of different concepts. At this point, you've learned most of the material that will be covered in the class, so your scores should accurately reflect your abilities. Every time you take a full practice test, keep track of the areas where you need more practice.

As I mentioned at the beginning of this article, I would recommend saving the most up-to-date official practice materials for later in the semester so that the format of the current test stays fresh in your mind. As you take each test, circle any questions where you were unsure about your answer. Even if your choice ends up being correct, you should still plan to go over these concepts, so you don't feel shaky about them on the real AP test. After you've finished taking the test with realistic time constraints! The purpose of taking practice tests is to diagnose your weaknesses so you can address them as efficiently as possible. DON'T go from one test to the next without taking a deeper look at what went wrong!

You'll end up wasting your time, and your second practice test is unlikely to demonstrate much improvement. Spend at least a couple of hours after each practice test doing practice problems and reviewing concepts that you didn't quite understand when they came up on the test. When you feel satisfied that you have a better handle on the background information and solution methods, you can take a second practice test to see how much you've improved. The process as a whole should work like this: Take and score first practice test 4 hours Evaluate mistakes 1. One cycle through all of these steps will take around hours, but you can repeat the steps ad infinitum until you're satisfied with your scores. If you find that you're not improving between practice tests, you'll need to reevaluate your study strategy. To master a complex subject like chemistry, you need to have a strong grasp of the fundamental concepts. Then, you can build on that understanding for more difficult problems.

Be sure to do lots of practice problems where you're required to justify your answers! The smug dude on top is you after studying with these practice tests! Just mentally replace the 1 with a 5 so that your smugness makes sense on the AP scale. Conclusion Practice tests are essential study tools, especially for AP Chemistry. Doing practice problems that align with the format and content of the real exam will help you to gain familiarity with the material and feel less stressed on test day. Try to start your studying with unofficial practice tests to build up a strong knowledge base, and then move onto official practice tests when you're ready to estimate your real AP score level. As you take practice tests, assess your mistakes and plan out your study time according to which areas need the most work. Make sure you start with basic concepts and then work your way up to more complex problems. Use these practice materials to detect gaps in your knowledge, and fill them before you take the test!

A The reaction is endothermic, meaning energy is a reactant appears on the left side of the equation. Adding stress to the left side increases the rate of the forward reaction, creating more products. D Weak bases do not ionize fully in solution, and most of the methylamine molecules will not deprotonate. The hydroxide and conjugate acid ions are created in a ratio and therefore will be equal.

D Moving across a period, atomic size decreases. Therefore, atom Z will be farthest to the right have the most protons , and thus will have the highest electronegativity value. C There are 1 mole of N2, 1 mole of Ar, and 2 moles of water in the container. D When a covalent substance undergoes a phase change, the bonds between the various molecules inside the substance break apart.

B g is equal to 2 moles of copper, which is what appears on the balanced equation. Twice as many moles being created means twice as many electrons are needed. With a lower concentration on the reactants side and a higher concentration on the products side, the reaction will shift left, decreasing the overall potential of the reaction. A The electron transfer does not happen across the salt bridge, eliminating options C and D. This is true for both A and B , meaning [NO] would decrease. A The only tricky bit here it to remember that boron is considered stable with only six electrons in its valence shell.

D At a higher temperature, the average velocity of the gas molecules would be greater. Additionally, they would have a greater spread of potential velocities, which would lead to a wider curve. D Nitrogen only has two shells of electrons while phosphorus has three, making nitrogen smaller and more able to attract additional electrons, meaning a higher electronegativity. Thus, oxygen has a higher electronegativity. B First, the mass of the oxygen must be calculated: Converting each of those to moles yields 0.

Thus, for every one oxygen atom there are three carbon atoms and six hydrogen atoms. The first equivalence point occurs at a volume of 10 mL, and thus the half-equivalence point is at a volume of 5 mL. If the nitrogen is reduced, that value must get more negative. The oxidation state of nitrogen in N2 is 0, so that fits the bill. A A buffer is made up of either a weak acid and its salt or a weak base and its salt. Option B has a strong acid and strong base, option C has a strong acid and its salt, and option D has a weak acid and a weak base.

A HCN will lose its proton to the hydroxide, creating a conjugate base and water. C The mass of the mixture is C This is an exothermic reaction; therefore heat is generated as a product. An increase in temperature thus causes a shift to the left, decreasing the numerator and increasing the denominator in the equilibrium expression. This decreases the overall value of K.

C The NaOH is limiting 0. However, the overall mixture will have a greater mass A In a polar solvent, polar molecules will be the most soluble like dissolves like. Of the four options, methanol and acetone would both have dipoles, but those of methanol would be significantly stronger due to the H-bonding. To balance the electrons, the reduction half-reaction must be multiplied by two and the oxidation half-reaction must be multiplied by three in order to have six electrons on each side. The nitrate ion is a spectator and would not appear in the net ionic equation. B Increasing the pressure in an equilibrium reaction with any gas molecules causes a shift to the side with less gas molecules—in this case, the product. A During a phase change, all of the energy added goes towards breaking the intermolecular forces holding the molecules together.

During this time, the speed of the molecules and thus the temperature does not rise. A In an endothermic reaction, heat is transferred into the reaction system. D None of the options would decrease the rate of reaction, which would be required for the half-life of the reactant to increase. C To determine the number of moles of SO3 created, stoichiometry must be used. As every 2 moles SO2 react with 1 mol of O2. Thus, 4 mol of SO3 are created and 4. B If 4 mol of SO3 are created and 4. Prior to the reaction there were A If all gases are at the same temperature, they have the same amount of kinetic energy. C One of the assumptions of kinetic molecular theory is that the amount of intermolecular forces between the gas molecules is negligible.
