Question

Write the product of the reaction

${\mathrm{H}}_2+\mathrm{S}\to \cdots \cdots$

Answer 1

The product of the reaction is H₂S (Hydrogen sulfide)

• On passing hydrogen through boiling sulfur, we obtain hydrogen sulfide (H₂S) gas.

. $\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Sulfur}}{\mathrm{S}\left(\mathrm{s}\right)}\to \underset{\mathrm{Hydrogen}\mathrm{sulfide}}{{\mathrm{H}}_2\mathrm{S}\left(\mathrm{g}\right)}$

• Hydrogen sulfide has the smell of rotten eggs.
• This gas is used in analytical work.
