Answer:

answer is below

Explanation:

In a combination reaction two or more substances are combined to form new substance while in the decomposition reaction one substance decomposes into two or more substances. Hence, the decomposition reactions are called opposite of combination reactions.

EXAMPLES

COMBINATION REACTIONS

example is magnesium oxide combining with carbon dioxide to produce magnesium carbonate.

DECOMPOSITION REACTION

breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

HI DEAR,

Decomposition reactions are known as opposite of combination reactions because in combination reactions two different compounds or elements join to form a single product..

On the other hand , in decomposition reactions , one compound breaks down into two or more products...

Decomposition rxn :

CO₂ = C + O₂

Combination rxn :

C + O₂ = CO₂

HOPE IT HELPS..
