Question

Hydrogen gas combines with chlorine gas to give ________ gas

Answer 1

• Combination reaction: It is the type of reaction in which two or more reactant combines to form one single product.
• The combination of Hydrogen(${\mathrm{H}}_2$) gas with Chlorine gas(${\mathrm{Cl}}_2$) results in the formation of a single product known as Hydrochloric gas($\mathrm{HCl}$).
• This reaction occurs in the presence of sunlight.
• $\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}+\underset{\mathrm{Chlorine}}{{\mathrm{Cl}}_2\left(\mathrm{g}\right)}\stackrel{\mathrm{Sunlight}}{\to }\underset{\mathrm{Hydrochloric}\mathrm{gas}}{2\mathrm{HCl}\left(\mathrm{g}\right)}$

Thus, Hydrogen gas combines with chlorine gas to give hydrochloric gas
