Answer: The balanced equation is .
Explanation:
A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.
For example,
Here, number of atoms on reactant side are as follows.
- V = 2
- O = 5
- Ca = 1
The number of atoms on product side are as follows.
- V = 1
- O = 1
- Ca = 1
In order to balance this equation, multiply Ca by 5 on reactant side. Multiply V by 2 and CaO by 5 on product side. Therefore, the equation can be rewritten as follows.
Now here, number of atoms on reactant side are as follows.
- V = 2
- O = 5
- Ca = 5
The number of atoms on product side are as follows.
- V = 2
- O = 5
- Ca = 5
Since, there are same number of atoms on both reactant and product side. So, the equation is now balanced.
Thus, we can conclude that the balanced equation is .
