Question

Complete and balance the following reaction.

$\mathrm{Ag}+\mathrm{S}\to \underset{\mathrm{Black}}{\mathrm{\_\_\_\_}}$

Answer 1

$\underset{\mathrm{Silver}}{2\mathrm{Ag}}+\underset{\mathrm{Sulphur}}{\mathrm{S}}\to \underset{\mathrm{Silver}\mathrm{sulphide}\left(\mathrm{Black}\right)}{{\mathrm{Ag}}_2\mathrm{S}}$

Silver is reacting with Sulphur to form Silver sulphide which is a dense black solid.

Balancing-

• We multiply the reactants and products in order to make the number of atoms in reactants and products are same.
• Balancing chemical equation follows the law of conservation of mass.
