I have attached a photo of the question. I can see that at equilibrium there is 0.64 moles of the reactants left. But according to the answer scheme, the answer is: Hydrogen 0.47 moles, Iodine 0.17 moles. But I don't get why. I see at the beginning that Iodine has 0.3 moles less than Hydrogen, but why are the answers 0.47 and 0.17?
Now I really seem to fall down at this type of question so if someone could explain this to me it would be really appreciated, just need to wrap my head around the concept!!!

Moles of h2 is original moles of h2- half of equilibrium Hi.
Same for i2 except moles of initial i2- half of moles of equilibrium hi.
Should be right.
