Question
Using the balances eqution and assuming all other reagents are in excess, how many hydrogen would be produced when 1.00 g of aluminum react?

What balanced equation?

Balance the equation
acid + aluminum> H2 gas + aluminum salt.
Lets look at some examples
6HCl + 2Al>>3H2 + 2AlCl3
so for each two Aluminum moles, you get 3 moles of hydrogen gas.
3H2SO4 + 2Al>> Al2(SO4)3 + 3H2
Again, for each two aluminum moles reacted, one gets three hydrogen moles.
Try it for other acids. So find the moles of aluminum in 1 gram, multiply it by 3/2, that is the moles of H2 you will get.
