9) A mixture of 80.0 g of Cr2O3 and 8.00 g of C is used to produce elemental Cr by the reaction below: Cr2O3 + 3 C > 2 Cr + 3 CO
a) What is the theoretical yield of Cr that can be obtained from the reaction mixture?
b) The actual yield is 21.7 g Cr. What is the percent yield for the reaction?

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "
