Types of Chemical Reactions

synthesis = two or more reactants combine to form a single product

• A + B = AB

• 2H2O (g) + O2 (g) —> 2H2O (l)

• metal nd oxygen combine to form a metal oxide

• metal oxides and water combine to form metal hydroxides

• non-metal oxides and water combine to form acid

decomposition reaction = a single reactant is decomposed or broken down into two or more products

• AB —> A + B

• production of non-metal oxide and water from acid or base

combustion = reaction of compounds that contain only carbon, hydrogen, and oxygen, with oxygen to form water and carbon dioxide

• HCO + O2 —> H2O + CO2

• complete combustion = when sufficient oxygen is present

• incomplete combustion = when there is not enough oxygen available, produces carbon dioxide, water, carbon monoxide, carbon
