Answer :
Answer: The balanced chemical equation is [tex]2NaNO_{3}(s) + Heat \rightarrow 2NaNO_{2}(s) + O_{2}(g)[/tex] and it is a decomposition chemical reaction.
Explanation:
A chemical reaction in which single compound is decomposed into two or more species is called a decomposition reaction.
For example, [tex]NaNO_{3}(s) + Heat \rightarrow NaNO_{2}(s) + O_{2}(g)[/tex]
As the compound [tex]NaNO_{3}[/tex] is decomposing to given two different substances. So, it is a decomposition reaction.
Here, the number of atoms on reactant side are as follows.
- Na = 1
- N = 1
- O = 3
The number of atoms on product side are as follows.
- Na = 1
- N = 1
- O = 4
To balance this equation, multiply [tex]NaNO_{3}[/tex] by 2 on reactant side and multiply [tex]NaNO_{2}[/tex] by 2 on product side. Therefore, the equation will be rewritten as follows.
[tex]2NaNO_{3}(s) + Heat \rightarrow 2NaNO_{2}(s) + O_{2}(g)[/tex]
Here, number of atoms on reactant side are as follows.
- Na = 2
- N = 2
- O = 6
The number of atoms on product side are as follows.
- Na = 2
- N = 2
- O = 6
Hence, this equation is balanced.
Thus, we can conclude that the balanced chemical equation is [tex]2NaNO_{3}(s) + Heat \rightarrow 2NaNO_{2}(s) + O_{2}(g)[/tex] and it is a decomposition chemical reaction.
