Question

What's the limiting reactant of Cu(SO4) + Fe --> Fe(SO4) + Cu. Explain.

Answer 1

for limiting agent, you need to find out the no. of mole of each reactants first... then according to their mole ratios, you can deduce which one is insufficient for reaction, that is the limiting agent.

Answer 2

I'm given 12 g of Cu(S04) and 2 g of Fe, do I start my calculations with CuS04 or Fe?

Answer 3

either one, because you need to find both :)
