Balance the equations (5pts each) and answer the posed question (5pts each) 1. C6H14 + O2 --> CO2 + H2O

When 60.00 grams of hexane is used, how many grams of water can be formed?

2 C6H14 (g) + 19 O2 (g) --> 12 CO2 (g) + 14 H2O (g)

Explanation:

For solving the stoichiometric calculations, we first need to do two steps. One of them is balancing the reaction equation. Here the balancing is done and we can see that 2 moles of hexane reacts with 19 moles of oxygen to produce 12 moles of carbon dioxide and 14 moles of water.

Now, for 2 moles of hexane, number of moles of oxygen required is 19.

So, for 7.2 moles of hexane, number of moles of oxygen required is.

= 68.4.

So 68.4 moles of oxygen is required.

the answer would be a

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.
