Which chemical equation is balanced? 2pcl5 + 2h2o → 2hcl + h3po4 pcl5 + h2o → hcl + h3po4 pcl5 + 3h2o → 5hcl + h3po4 pcl5 + 4h2o → 5hcl + h3po4

Option (d) is the correct answer.

Explanation:

An equation will be said balanced equation when there are equal number of atoms on both reactant and product side.

For example,

Number of atoms on reactant sides are as follows.

P = 1

Cl = 5

H = 8

O = 4

Number of atoms on product side are as follows.

P = 1

Cl = 5

H = 8

O = 4

Thus, there are equal number of atoms on both reactant and product side. Hence, this equation is balanced.
