- 4. A chemical equation where the number of atoms of each element is the same on both the reactant and product sides.
- 5. A chemical equation that shows the chemical formulas of the reactants and products but is not balanced.
- 9. A type of chemical reaction where two or more reactants join together to form a single product.
- 10. A type of chemical reaction where a single compound breaks down into two or more simpler substances.
- 11. The insoluble solid that forms and separates out of a solution during a precipitation reaction.
- 12. A process or reaction that absorbs heat from its surroundings.
- 13. A substance that is formed as a result of a chemical reaction.
- 14. The unpleasant smell and taste that develops in fats and oils when they are exposed to air for a long time.

Down
- 1. A substance that takes part in and undergoes change during a chemical reaction.
- 2. A type of chemical reaction where a more reactive element takes the place of a less reactive element in a compound.
- 3. A solution in which the solvent is water, often indicated by the symbol "(aq)" after a chemical formula.
- 6. A process or reaction that releases heat to its surroundings.
- 7. A type of double displacement reaction where an insoluble solid forms and separates from the solution.
