Types of Chemical Reactions
Combustion
Carbon containing compounds, fuel burns in oxygen from the air to produce carbon dioxide, CO2, water, H2O and heat or flame.
CH4 + 2O2 ----> CO2 + 2H2O + energy
CH4 + 2O2 ---> CO2 + H2O
Acid-base
A reaction of an acid and a base. And produces a salt and water
NH3 + HCl ---> NH4Cl
H2SO4 + 2KOH ---> K2SO4 + 2H2O
Double-replacement
Two ionic compounds in aqueous solution switch anions and produce an insoluble substances
BaCL2 + K2CrO ---> BaCrO + 2KCl
NaCl + LiNO3 ---> NaNO3 + LiCl
Decomposition
A single compound is broken into two or more simpler substances
Ni(HCO3)2 ---> NiCO3 + H2O + CO2
CaCO3 ---> CaO + CO2
Single-replacement
A reaction in which more active metal displaces another less active metal in a compound
Fe + 2HCl ---> FeCl2 +H2
2Na + 2H2O ---> 2NaOH + H2
Combination
A reaction in which simpler substances are combined into a more complex compound
2Mg + O2 ---> 2MgO
S + O2 ---> SO2
