Question

Identifying and Balancing Chemical Equations
Name:
Balance these equations (even if the value is one put it in the blank) :
the type of reaction. (Synthesis, Decomposition, Single Replacement, Double !
Combustion)
Type
1. _HgO + _Hg + _02

Answer 1

Answer:

decomposition

Balanced chemical equation:

2HgO → 2Hg + O₂

Explanation:

Chemical equation:

HgO → Hg + O₂

Balanced chemical equation:

2HgO → 2Hg + O₂

The given reaction shows the decomposition reaction. Mercury oxide decompose and produced its constituent elements mercury and oxygen.

The oxidation state of mercury is +2 while that of oxygen is -2.

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

General equation:

AB → A + B
