Given the reaction 4NH3(g) + 502(g) 4NO(g) + 6H2O(g)
Which is the limiting reactant when 71.2 grams of NH3 react with 112 L of O2? (Use grams of NO as your product)

[a] 71.2g NH3
[b] 4 mol NO
[c] 6 mol H2O
[d] 112L 02

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

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.
