Chloromethane, , arises from microbial fermentation and is found throughout the environment. It is also produced industrially, is used in the manufacture of various chemicals, and has been used as a topical anesthetic. How much energy is required to convert 74.0 g of liquid to a vapor at its boiling point, –24.09 °C? (The heat of vaporization of is 21.40 kJ/mol.) Energy required = kJ

31.36 KJ/mol

Explanation:

mass of the liquid = 74.0 g

heat of vaporization = 21.40 kJ/mol

constant boiling point temperature = 24.09 °C

heat required to vaporize 74.0g = heat of vaporization × mole

mole of Chloromethane = 74.0 g / 50.49 (g/mol) = 1.466 mol

energy required = 1.466 mol × 21.40 KJ/mol = 31.36 KJ/mol

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.

the answer is c i took the test
