Question 41

Hydrogen reacts with chlorine to form hydrogen chloride.

H2(g)+Cl2(g)→2HCl(g)\mathrm{H_2(g) + Cl_2(g) \rightarrow 2HCl(g)}H2​(g)+Cl2​(g)→2HCl(g)

Hydrogen is in excess.

Relative formula masses: Cl2=71\mathrm{Cl_2} = 71Cl2​=71 and HCl=36.5\mathrm{HCl} = 36.5HCl=36.5.

Calculate the maximum mass of hydrogen chloride produced when 21.3 g of chlorine reacts completely.
