Question

if 0.4 molecules is added to hydrochloride acid containing 0.62 molecule how many moles of H2 are produced what is the limited reagent​

Answer 1

1 mole Zn reacts with 2 moles HCl

0.4 mole Zn reacts with 0.8 moles HCl

>>But 0.8 moles HCl is not available so HCl is limiting reagent, HCl will decide the quantity

2 moles HCl reacts with 1 mole Zn

0.62 moles HCl reacts with 0.31 mole Zn

1 mole Zn gives 1 mole H2

0.31 mole Zn gives 0.31 mole H2

>>0.31 moles H2 <--------Answer
