Learn about chemical, nuclear and thermodynamic reactions to prepare for the Advanced Placement (AP) chemistry exams.

This free online course provides you with an in-depth understanding of the physical states of matter and how it can transition between different states. Before calculating the number of particles of a substance, it is important to understand stoichiometry and consideration of the balanced chemical equation. This course explores the concept of heterogeneous and homogeneous mixtures, including the types of pure substances. It introduces you to the concept of vapour pressure and Dalton’s law of partial pressure. Have you considered the process of dissolving sodium chloride (NaCl) in water? This course will teach you the metric system, dimensional analysis and the steps that are important for having successful dimensional analysis. You will also learn about the properties of materials based on the structure and shape of atoms, giving you a better understanding of the concept of nuclei, electrons, neutrons and protons.

If you want a detailed understanding of the dynamics of various chemical reactions, then you should sign up for this course. You will be able to explain how the mass of solid silver plus molality and molarity can be calculated. The material will help you understand the factors that affect vapour pressure, ideal gas law with examples of problems and their solutions. Explore how the rate of disappearance of reactants can be calculated. You will be taken through the effect of surface area as well as of concentration or pressure on reaction rate. Study the different ways of determining the rate law or the order of the reaction. Do you know there are factors that can affect equilibrium and the oxidation number of an element in a compound? This course explains the procedure for balancing redox reactions using the half-reaction or ion-electron. If you have any difficulty understanding chemical and nuclear reactions, including intermolecular forces, then this course is for you.

Furthermore, learn about the different factors that affect the reaction rate and how to use Gay-Lussac’s law for the calculation of change in pressure gas. You will be able to explain the temperature effects on solubility and the types of the covalent bond by electron sharing. This course will help you have a better understanding of the general concept of, and terminologies used in thermodynamics, as well as the different forms of energy. Do you know there are definite expressions of a system, surroundings, and boundary in thermodynamics? You will learn how to predict the spontaneity of redox reactions and the electrode process of values. Explore the driving forces of a chemical reaction, the definition of Gibbs free energy and the effect of standard state enthalpy. The course improves your understanding of the classification of the alkenes and alkynes. If you are considering taking the AP chemistry exams, this free online course provides great preparation and revision.
