Acrylonitrile (C3H3N) Is The Starting Material For Many Synthetic Carpets And Fabrics. It Is Produced By The Following Reaction: 2C3H6 (g) + 2NH3 (g) + 3O2 (g) = 2C3H3N (g) + 6H2O (g) If 15.0 G C3H6, 10.0 G O2, And 5.00 G NH3 Are Reacted, What mass of the acrylonitrile can be produced assuming 100% yield?

11.072 g

Explanation:

2 C3H6 (g) + 2NH3 (g) + 3O2 (g) = 2C3H3N (g) + 6H2O (g)

molar mass of Acrylonitrile (C3H3N) = 53.06 g/mol

molar mass of C3H6 = 42.08 g/mol =

molar mass of NH3 = 17.031 g/mol

molar mass of O2 = 15.999 g/mol

mole of C3H6 = 15 g / 42.08 g/mol = 0.3565 mol

mole of NH3 = 5 g / 17.031 g/mol = 0.294 mol

mole of O2 = 10 g / (15.999 x 2g/mol) = 0.313

finding the limiting reagent be comparing the mole

2 mole of C3H6 react with 2 mole of NH3  and 3 mole of O2 to yield 2 mole of C3H3N

0.209 mole of  C3H6 react with 0.209 mole of NH3  and 0.313 oxygen

mass of Acrylonitrile (C3H3N) =  53.06 g/mol × 0.209 mol = 11.072 g

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? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
