- What is a synthesis reaction?
- A reaction in which two or more substances combine to form one product.
- What is a decomposition reaction?
- A reaction in which one compound breaks down into two or more simpler substances.
- In a single replacement reaction, what occurs?
- One element replaces another element in a compound.
- What occurs in a double replacement reaction?
- The cations and anions of two compounds exchange with each other.
- What is a combustion reaction?
- A reaction in which a substance reacts with oxygen, usually releasing heat and light.
- What are the products when a hydrocarbon undergoes complete combustion?
- Carbon dioxide and water.
- Define molar ratio.
- The ratio of the coefficients of any two substances in a balanced chemical equation.
- What does each coefficient in a balanced equation represent?
- The number of moles of that substance that reacts or is produced.
- What is Avogadro's number?
- 6.022 × 10^23 particles per mole.

- Define percent composition.
- The mass of an element divided by the total mass of the compound, expressed as a percentage.
- What is an empirical formula?
