there are four types of reaction
1. combination reaction-reaction in which two or more element combine to form a single .
2.displacement reaction-reaction in which more reactive element displaces less reactive element.
3.decomposition reaction-reaction in which element by atom combine to form a single.
4.double displacement reaction-reaction in which elements places In their aquas solution .

1.thermal decomposition-decompotition takes place in the presence of heat.
2.photodecomposition -decomposition takes place in the presence of sunlight
3.electrolytic decomposition or electrolysis -decomposition takes place in the presence of electricity.
