Answer: The balanced equation for the given reaction is
.
Explanation:
A chemical equation which contains same number of atoms on both reactant and product side.
For example,
Here, number of atoms on reactant side are as follows.
- S = 1
- O = 4
Number of atoms on product side are as follows.
- S = 1
- O = 3
To balance this equation, multiply by 2 on reactant side and multiply
by 2. Hence, the equation will be re-written as follows.
Here, number of atoms on reactant side are as follows.
- S = 2
- O = 6
Number of atoms on product side are as follows.
- S = 2
- O = 6
Now, there are same number of atoms on both reactant and product side. So, this equation is balanced.
Thus, we can conclude that the balanced equation for the given reaction is .
