CIE Chemistry ATP P.42 MCQ query :

[Shadow]

H2SO4 was in b. Number of moles found were 4 x 10(-4). Mole ratio was 1:1. So H2 produced doubled in b.

Dont exactly remember the vol n conc of H2SO4 in B, but i checked all of them twice, only C produced double H2

H2SO4 can't be in option b then. I remember my moles produced were double, and I ticked b. If b is wrong, then in option b, HCL should be present.

That's not the complete question. You're missing the names of the acid, which is necessary because of the comparison with mole ratio. I need to know which acid was used in part b. I'd know the answer then.

the answer was C
