Question

Which chemical equation is balanced?

Answer 1

I think the answer is PCl5 + 4H2O → 5HCl + H3PO4

Answer 2

Answer: 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, $PCl_{5} + 4H_{2}O \rightarrow 5HCl + H_{3}PO_{4}$

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.
