#### Answer:

Clearly the mole ratios of the reactants are

#### Explanation:

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

....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
