6.54 of zink must react with excess dilute hydrochloride acid calculate the volume of the hydrogen at s.t.p zn+21+cl= zncl+ h(g) [zn=65.4]
Answered by oobleck
how many moles produced?
22.4 L/mole at STP
Answered by DrBob222
The equation is
Zn(s) + 2HCl(aq) ==> ZnCl2(aq) + H2(g)
mols Zn = grams/atomic mass = ?
mols Zn = mols H2 (from the coefficients in the balanced equation)
L H2 = mols H2 x 22.4 L/mol = ?
