Best ResponseYou've already chosen the best response.3Remember that electricity are just electrons, you're using these electrons to reduce \(H^+\) to \(H_2\).

Best ResponseYou've already chosen the best response.0@aaronq , At first I was thinking of using Friday law : \[\frac{ Mas(x) }{ equivalentMass(x) } = \frac{ Mass(Y) }{ EM(Y) }\] But I don't have either equivalent masses.

Best ResponseYou've already chosen the best response.0I think equivalent masses are both for (H) so Mass(X) = Mass(Y) Moles of X = Moles of Y = 2 ?

Best ResponseYou've already chosen the best response.3you dont actually need any formulas, to answer the question to you only need to think conceptually and see where the electrons are going. You used the same amount of electricity (electrons) in both cases, right?  yes, 2 moles, the same amount of moles.

Best ResponseYou've already chosen the best response.0Thanks. I never feel convinced of my answer until I assure it with formula. But was using the formula right ?

Best ResponseYou've already chosen the best response.0And what was confusing my is that H2SO4 < 2 H so in mole = 2 * NA HCl> 1 H so in mole = 1 * NA

Best ResponseYou've already chosen the best response.3yeah, but unless HCl was limited then you would get as much H2 as you could reduce. in other words: 2 HCl + e > 2 H2 + Cl^

Best ResponseYou've already chosen the best response.3i guess using the formula works out in this case, although it's really not needed
