Clearly the mole ratios of the reactants are 1:1, and 2 equiv of product result.

Explanation:

And this can be seen from the stoichiometric equation you have already written.....alternatively we could write....

12H2(g)+12Cl2(g)HCl(g)

....which preserves the same molar ratio, i.e. the SAME STOICHOMETRY. And thus we could say that 1 equiv of dihydrogen reacts with 1 equiv of dichlorine (and note that all of the reactive elemental gases are binuclear!) to gives the 2 equiv of hydrogen chloride gas.....

And likewise we could say that 1g of dihydrogen combines with 35g of dichlorine to give 36g of hydrogen chloride gas. Stoichiometry is maintained: garbage in equal garbage out.
