Question

Which of the following equations is balanced?

Answer 1

A. there is four phosphorus and 10 oxygen on each side

Answer 2

Answer: Option (A) is the correct answer.

Explanation:

A balanced equation is defined as the equation which contains same number of atoms on both reactant and product side.

For example, $4P + 5O_2 rightarrow 2P_2O_5$

Here, no. of atoms on reactant side are as follows.

• P = 4

• O = 10

No. of atoms on product side are as follows.

• P = 4

• O = 10

As the number of atoms on both reactant and product side are same in this reaction equation. Hence, it is a balanced reaction equation.

Thus, we can conclude that $4P + 5O_2 rightarrow 2P_2O_5$ equations is balanced.
