If you are a higher education faculty member interested in seeing questions, please fill out this request form. For example, you may need to only work 5/10 problems. This is a collection of questions dealing with conversions between temperature units. Study for Exam 1 of General Chemistry. Get to the exam early enough that you have time to get organized and relax. This is a collection of questions dealing with naming ionic compounds and predicting the chemical formula from the compound name. Journal of Neurophysiology 104: 51–60. The basic measurement of concentration in chemistry is molarity. Key Concepts: Terms in this set (53) Science. Read the instructions for the test! BACK. Sometimes chemistry tests allow you to choose which questions to answer. To use the Periodic Table of Elements during the exam, select the Help icon from the menu at the top of the screen and then select the Periodic Table tab. This section is worth 45% of your total score. The Ideal Gas Law is the relationship described by the equation: where P is pressure, V is volume, n is the number of moles of an ideal gas, R is the ideal gas constant and T is the temperature. Keep in mind that the empirical formula of a compound is a formula that shows the ratio of elements present in the compound but not the actual numbers of atoms found in the molecule. Electronic structure dictates the size, shape, and valence of atoms. 1155 Sixteenth Street, NW, Washington, DC 20036, USA | service@acs.org | 1-800-333-9511 (US and Canada) | 614-447-3776 (outside North America), Copyright © 2020 American Chemical Society.

Over 70% of Local Sections use the Local Section Exam prepared by the ACS Chemistry Olympiad Examination Task Force. Review the unit conversion test questions above if you need to brush up on unit conversions. Chemical equilibrium for a reversible chemical reaction occurs when the rate of the forward reaction equals the rate of the reverse reaction. This practice test deals with finding the molecular formula of chemical compounds. In this invaluable resource, the chief reader of the AP Exam compiles feedback from members of the AP Reading leadership to explain how students performed on the FRQs, summarize typical student errors, and address specific concepts and content with which students have struggled the most that year. The ratio of the forward rate to the reverse rate is called the equilibrium constant. Some of these are pretest questions that will not be scored.

The app also includes diagnostics to help you pinpoint strengths and weaknesses. What is your brain chemistry like? Second, it gets you some quick points, so if you run out of time on the test then at least you got some right answers. Even if they do, if you can eliminate even one possibility, it's worth it to take a guess. Semester Hours: 6. For more, please consult our Terms of Service.
