Answer: Option (D) 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, [tex]PCl_{5} + 4H_{2}O \rightarrow 5HCl + H_{3}PO_{4}[/tex]
Number of atoms on reactant side 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
Since, there are same number of atoms on both reactant and product side. Hence, this equation is balanced.
Thus, we can conclude that out of the given options [tex]PCl_{5} + 4H_{2}O \rightarrow 5HCl + H_{3}PO_{4}[/tex], this chemical equation is balanced.
