Question

1. Write the balanced reaction of Al with CuCl2.

2. What is the limiting reagent if 0.5 g Al is reacted with 3.5 g CuCl2? (Reminder: CuCl2 is a dihydrate)


3. What is the theoretical yield of copper produced by the reaction above?


help plsss

Answer 1

above answer is right :)

Answer 2

1.
`\sf \: Al + CuCl_2 = AlCl_3 + Cu`

`\\`

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.

Hope it helps uh :)♡~
