Question

Explain the following redox reactions with one example in each case:
(i) Combination reactions
(ii) Decomposition reactions

Answer 1

1. Combination reaction: The reaction in which the two or more reactants comes together and gives a single product is called combination reaction.
ex. C+O2=C02

2. Decomposition reaction: The reaction in which there is single reactant and from which two or more products are formed is called decomposition reaction.
ex. 2H20=2H2+02.
