What is the theoretical yield of copper produced by the reaction of: 0.2 g Al reacted with 3.5 g CuCl2 x H2O? (CuCl2 x H2O is a dihydrate when calculating the molecular weight) Hint.) First find the limiting reactant, then the molecular weights of copper by the aluminum and the (Copper Chloride times water)​

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

the answer is 0.8m.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
