Answer 2

• Decomposition reactions are the reactions in which a compound breaks down or decomposes to form two or more substances.

• These reactions are exactly opposite to combination reactions. We know that there is only one product in combination reactions.

• Similarly, there is only one reactant in decomposition reactions.

• General equation of a decomposition reaction is:

XY ⟹ X + Y
