Answer:

there are four types of chemical reactions

1) combination reaction

2) decomposition reaction

3) displacement eaction

4) double displacement reaction

Explanation:

1) combination reaction: when two or more reactants combine together to form one single product.

for example:CH4 + O2 = CO2 + 2H2O

2) decomposition reaction: when one reactant breaks down to form two or more products.

for example CaCO3 = CaO + CO2

3) displacement reaction : when more reactive element displaces less reactive element.

for example Fe + CuSO4 = FeSO4 + Cu

4) double displacement reaction: the reaction in which exchange of ions takes place.

for example NaSO4 + BaCl2 = BaSO4 + 2NaCl
