The conservation of atoms in chemical reactions leads to the principle of conservation of matter and the ability to calculate the mass of products and reactants. Gases and their Properties 4. The Kinetic Molecular theory describes the motion of atoms and molecules and explains the properties of gases. Acids and Bases 5. Acids, bases, and salts are three classes of compounds that form ions in water solutions.
Solutions are homogenous mixtures of two or more substances.
Chemical Thermodynamics 7. Energy is exchanged or transformed in all chemical reactions and physical changes of matter. Reaction Rates 8. Chemical reaction rates depend on factors that influence the frequency of collision of reactant molecules. Chemical equilibrium is a dynamic process at the molecular level.
