Given the balanced equation 2C4H10 + 13O2 → 8CO2 + 10H2O, how many moles of CO2 are produced when 14.9g of O2 are used?

The number of moles of produced are, 0.287 moles.

Explanation : Given,

Mass of = 14.9 g

Molar mass of = 32 g/mol

First we have to calculate the moles of

Now we have to calculate the moles of

The balanced chemical equation is:

From the reaction, we conclude that

As, 13 mole of react to give 8 moles of

So, 0.466 mole of react to give mole of

Therefore, the number of moles of produced are, 0.287 moles.

c.

explanation:

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.
