Physical and chemical processes can be classified by the changes occurring on the molecular level. In general, chemical processes involve changes in chemical bonds, while physical processes involve changes only in intermolecular forces.
This unit introduces chemical reactions, the processes that create and transform matter. Learn about net ionic equations, reaction stoichiometry, titration, common reaction types, and more. Practice what you’ve learned and study for the AP Chemistry exam with 80 AP-aligned questions.
A student investigates the reactions of nitrogen oxides. One of the reactions in the investigation requires an equimolar mixture of NO(g) and N0 2 (g), which the student produces by using the reaction represented
Download free-response questions from past AP Chemistry exams, along with scoring guidelines, sample responses from exam takers, and scoring distributions.
18 cze 2024 · Study Guides for Every AP Chemistry Unit. The AP Chemistry exam covers a ton of content. When I say a ton, I mean a TON. The course covers everything from quantum mechanics and atomic structure to properties of states of matter to acid-base titrations.
In this article, we'll look at how we can use the stoichiometric relationships contained in balanced chemical equations to determine amounts of substances consumed and produced in chemical reactions. Balanced equations and mole ratios.
This question required students to determine the solubility of a sparingly soluble salt in aqueous solution and then to provide a rationalization for the differences in lattice energy between two crystalline ionic compounds.
