Answer 1

• Word equation- An equation with the name of the reactants and products involved in a chemical reaction.
• When hydrogen gas is passing through molten sulphur, it forms hydrogen sulphide gas, which smells like rotten eggs.

$\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Molten}\mathrm{sulphur}}{\mathrm{S}\left(\mathrm{l}\right)}\to \underset{\underset{\mathrm{Rotten}\mathrm{egg}\mathrm{smell}}{\mathrm{Hydrogen}\mathrm{sulphide}}}{{\mathrm{H}}_2\mathrm{S}\left(\mathrm{g}\right)}$
