Answer: The balanced equation is [tex]V_{2}O_{5} + 5Ca \rightarrow 2V + 5CaO[/tex].

Explanation:

A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.

For example, [tex]V_{2}O_{5} + Ca \rightarrow V + CaO[/tex]

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.

[tex]V_{2}O_{5} + 5Ca \rightarrow 2V + 5CaO[/tex]

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 [tex]V_{2}O_{5} + 5Ca \rightarrow 2V + 5CaO[/tex].
