aoa what will be the ans to this mcq 2Al + 3CuCl₂ → 2AlCl₃ + 3Cu. 5.4 g of Al (Ar = 27) is added to a solution containing 30 g of CuCl₂ (Mr = 134). After the reaction, 15.36 g of Cu (Ar = 64) is isolated. The percentage yield of copper is: A 60% B 70% C 80% D 90 it was in manzil test 1 ....

This question has a typo. When I solved this I assumed aluminium as limiting reactant although copper chloride is the limiting reactant. Taking copper chloride as limiting reactant will make the actual yield greater than the theoretical yield which is not possible. So take aluminium as limiting reactant and u will get 80% yield

Yes and Mera answer 107 a raha tha but it must be less than 100 toh mainay 90 kiya tha but show ho raha tha k yeah galat hai mainay AI sai poocha tha toh woh meh raha tha 90 e ho ha
