Question

Explain given chemical reactions with suitable example
(i) combination reaction
(ii) decomposition reaction
(iii) displacement reaction​

Answer 1

Answer:

Combination reaction = the reaction in which two or more reactants reacts with each other and form product. example - C + O2 ------> CO2

Decomposition reaction = the reaction in which a compound spits into two or more substance. example-

2H2O -------> 2H2 +O2

Displacement reaction = the reaction in which the more reactive substances displace the less reactive substance..example- Fe + CuSO4 -------> FeSO4 + Cu
