- Decomposition
- A single compound breaks down to two or more products.
- Single Replacement
- One element replaces a second in the compound.
- Double Replacement
- Involving an exchange of positive ions between two ionic compounds.
- Combustion
- An element or compound reacts with oxygen, producing energy in the form of heat and light.
- Combination
- When two reactants combine into one product.
- Mole Ratio
- A conversion factor derived from the coefficients of a balanced chemical equation interpreted in terms of mass.
