Question

2.what is the limiting reagent if 0.5 g Al is reacted with 3.5g CuCl² (reminder:CuCl2 is a dihydrate).
3. what is the theoretical yield of copper produced by the reaction above?​

Answer 1

The theoretical yield of copper in this reaction is 1.306g.

Answer 2

2. CuCl₂·2H₂O is limiting reactant.

Chemical reaction: 3CuCl₂·2H₂O + 2Al → 3Cu + 2AlCl₃ + 6H₂O. m(Al) = 0,5 g.

3. The molar mass of copper is 63.546 grams per mole.

If we multiply everything out, we'll get 0.50722 grams of copper, which is our theoretical yield.
