Question

2.

Which chemical equation represents a decomposition reaction?
A. Ba + S + Bas
B. CHgO → Hg + 30,
C. 2FeO + C + 2Fe + CO,
D. Sil, + 2Mg → Si + 2MgI,

Answer 1

The correct option is B) CHgO → Hg + 30

Step-by-step explanation:

A decomposition reaction can be described as a type of reaction in which a single compound or fragment breaks down into two or more than two entities.

The reaction mentioned in option B depicts a decomposition reaction:

CHgO → Hg + 30

In this decomposition reaction, CHgO is the compound which is being broken down into the elements Hg and O.
