Question

In which of the following reaction the physical state of the reactants or the product is not correctly represented?

Options:

A .

N_{2} (g) + 3 H_{2} (g) ⇋ 2 {NH}_{3} (g)

B .

{SO}_{2} (g) + {Cl}_{2} (g) ⇋ {SO}_{2} (g)

C .

Zn (s) + HCl (aq) ⇋ {ZnCl}_{2} (aq) + H_{2} (g)

D .

{NH}_{3} (s) + HCl (aq) ⇋ {NH}_{4} Cl (s)

Answer: Option D
:
D

While writing a chemical equation letter are used in brackets or subscripts next to the chemical formulae to specify the physical state of the reactants and the products.

- s is for solids

- l is for liquids

- g for gas

- aq is aqueous solution

The reaction in which the physical state of the reactants or the product is not correctly represented is:

${NH}_{3} (s) + HCl (aq) ⇋ {NH}_{4} Cl (s)$

This is because ammonia $({N H}_{3})$ is a gas.
