2 or more reactants combine to make 1 product.

When 1 reactant breaks down into 2 more products.

When something is burned. Oxygen (O2) is always a reactant. Carbon dioxide (CO2) and water (H2O) are always products.

One element replaces a similar element in a compound.

Two ionic compound reactants switch ions, forming two new ionic compound products. Usually results in the formation of a precipitate.
