You already saw that 1.00 g of al should yield 3.53 g of copper for the reaction below. 3cucl2(aq) + 2al(s)⟶ 2alcl3(aq) + 3cu(s) however, impurities and errors can occur easily. suppose that only 2.86 g of copper is produced. what is the percent yield of the reaction

81 %

Explanation:

Percent yield = actual yield/ theoretical yield x 100

Percent yield is the ratio of the actual yield to the theoretical yield  

Given,  

Actual yield = 2.86 g

Theoretical yield = 3.53 g  

Percent yield == 81 %

a chemical reaction

explanation:

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
