Question

differenciate between combination reaction and decomposition reaction​

Answer 1

Explanation:

combination rxn

when there are only 2 reactants and they both combines and form a product of different properties. the reaction is known as combination rxn.

For example-

H2 +O2 = 2 H2O

decomposition rxn

when there is only one reactant and more than two products with different properties. the reaction is known as decomposition rxn.

For example-

AgCl = Ag + Cl2
