Question

2 moles of zinc reacts with cupric chloride solution containing 6.023×10*22 units of cupric cloride.calculate the moles of copper obtained

Answer 1

Zn + CuCl2 =====> Cu + ZnCl2
1 mole Zn react with 1 mole of CuCl2

given ,
mole of CuCl2=6.023 x 10^22/6.023 x 10^23 = 0.1

here CuCl2 is limiting reagent so,
reaction occur only related to CuCl2
because
1 mole CuCl2 form 1 mole Cu
so, 0.1 mole CuCl2 form 0.1 mole Cu
hence ,
0.1 mole of Cu form

Answer 2

Answer:

0.1 mole of cu form
