Question

The equation shows the reaction between zinc metal and hydrochloric acid.


Zn(s) + 2HCl(aq) mc014-1.jpg ZnCl2(aq) + H2(g)


What is the theoretical yield of hydrogen gas if 5.00 mol of zinc are added to an excess of hydrochloric acid?
5.05 g
10.1 g
182 g
682 g @aaronq

Answer 1

help me!

Answer 2

Zn(s) + 2HCl(aq)= ZnCl2(aq) + H2(g)

Answer 4

You just need to work it out with Zinc as the limiting reactant. It's a straight forward stoichiometry problem.

Answer 5

is it 182g @aaronq

Answer 6

hmm....

Answer 7

post your work

Answer 8

I have absolutely no idea. I JUST did Stoichemistry, and I still don't really get it. Especially theoretical yield. Ummm....look for calculators online?
I'll keep looking at it tho...

Answer 9

5.05 is right out, I would think

Answer 10

Yeah, I would guess 182

Answer 11

10.2 doesn't seem like enough, 682 seems too much
