Question

Identify the balanced chemical equation that represents a decomposition reaction.

2Fe(OH) 3 ⟶ 2FeO 3 + H 2O
CuSO 4 ⟶ CuO + 2SO 3
2Fe(OH) 3 ⟶ Fe 2O 3 + 3H 2O
P 4 + 3O 2 ⟶ P 2O 3

Answer 1

Option C

Step-by-step explanation:

A decomposition reaction is a type of reaction in which one reactant breaks down in to two or more products.

Here in option C

On both reactant and products side

• Fe=2
• O=6
• H=6

Hence balanced

Answer 2

Identify the balanced chemical equation that represents a decomposition reaction.

2Fe(OH) 3 ⟶ 2FeO 3 + H 2O

CuSO 4 ⟶ CuO + 2SO 3

2Fe(OH) 3 ⟶ Fe 2O 3 + 3H 2O

P 4 + 3O 2 ⟶ P 2O 3
