4. A balanced equation in chemistry has the same number of atoms of each element on both the reactant and product sides of the chemical reaction, while an unbalanced equation has a different number of atoms of one or more elements on each side
5. The square brackets around the H ‍ just mean that we are referring to its concentration.
6. raises the base to the log's value to get the original number
8. a logarithm, which is a mathematical function used to express a number as the power to which a base (usually 10) must be raised to obtain that number
13. an insoluble solid that forms when two solutions react
14. make (a liquid) thinner or weaker by adding water or another solvent to it.
15. the process where a solute (a substance being dissolved) breaks down and mixes with a solvent to form a homogeneous mixture called a solution

1. a chemical equation that only shows the ions or molecules directly involved in a chemical reaction, excluding any "spectator ions" which are present but do not participate in the reaction itself
2. the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons
3. Dissociation in chemistry is a general process in which molecules separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner.
7. indicates all of the dissociated ions in a chemical reaction.
9. cations and anions in aqueous solution combine to form an insoluble ionic solid called a precipitate.
10. an ion that is present in a chemical reaction but does not participate in the reaction itself
11. the usually clear liquid overlying material deposited by settling, precipitation, or centrifugation.
12. the ability of a substance to dissolve in another substance
