The combustion of carbon disulphide is exothermic compounds with enthalpies of formation of 405 and 293kj/mol respectively. calculate the heat of formation of carbon disulphide​

1. they vary with a higher number because boiling is way hotter than melting

the correct answer is:

a. formation of precipitation

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.
