Question

Write, in sequential steps, balanced equations for the following word equations. Indicate experimental conditions and the physical states of reactants and products

$\mathrm{Hydrogen}+\mathrm{Chlorine}\to \mathrm{Hydrogen}\mathrm{chloride}\mathrm{gas}$

Answer 1

• Hydrogen gas reacts with chlorine gas to form hydrogen chloride gas.
• The skeletal equation of the above reaction can be written as $\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2}+\underset{\mathrm{Chlorine}}{{\mathrm{Cl}}_2}\to \underset{\mathrm{Hydrogen}\mathrm{chloride}}{\mathrm{HCl}}$
• Hydrogen and chlorine both are not balanced so we multiply the product side with 2
• The equation becomes ${\mathrm{H}}_2+{\mathrm{Cl}}_2\to 2\mathrm{HCl}$
• The above reaction takes place in the presence of diffused sunlight.
• Therefore, the final reaction is ${\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{Cl}}_2\left(\mathrm{g}\right)\to 2\mathrm{HCl}\left(\mathrm{g}\right)$
