In which of the following reaction the physical state of the reactants or the product is not correctly represented?
NH3(s)+HCl (aq)⇋NH4Cl (s)
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:
NH3(s)+HCl (aq)⇋NH4Cl (s)
This is because ammonia (NH3) is a gas.
