Solution

Q.
Read the passage carefully and answer the following questions from (i) to (v):

A decomposition reaction is opposite to a combination reaction. A single reactant breaks down to form two or more products in a decomposition reaction. Thermal decomposition reaction uses energy in the form of heat to decompose reactants. Electrolytic decomposition reaction involves the use of electrical energy to break reactant molecules. Photolysis or photochemical decomposition involves the use of light energy.
