Question

V2O5 + Ca = V + CaO balance the eqaution

Answer 1

Answer: The balanced equation is $V_{2}O_{5} + 5Ca \rightarrow 2V + 5CaO$.

Explanation:

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

For example, $V_{2}O_{5} + Ca \rightarrow V + CaO$

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.

$V_{2}O_{5} + 5Ca \rightarrow 2V + 5CaO$

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 $V_{2}O_{5} + 5Ca \rightarrow 2V + 5CaO$.
