In a reaction between Zinc and Hydrochloric acid, what is the limiting reactant

Question

aaronq · Answer

you need to know the balanced reaction and the amount of moles of each reactant.

Sorry, meant to give that
The balanced equation: Zn (s) + 2 HCl (aq) --> ZnCl2 (aq) + H2 (g) 
.003 moles of zinc and .06 moles of HCl

aaronq · Answer

Compare the 'normalized' (in a statistical sense) moles of each reactant. To do this, you divide the moles by the stoichiometric coefficient.

$\sf \dfrac{moles~of~Zn}{Zn's~coefficient}=$

$\sf \dfrac{moles~of~HCl}{HCl's~coefficient}=$

which ever has less is the limiting reactant.

no probs

jfraser · Answer

it entirely depends on how much of each reactant you have, as @aaronq says
