Which of the following is an acid-base neutralization reaction? a. sn+2hbr——> snbr2+h2 b. hcl+> kcl+h2o c. 2alcl3+ 3ca(oh)2——> 2al(oh)3+ 3cacl2 d. 2c2h6+7o2—-> 4co2+ 6h2o

Only one equation here has an acid and a base as reactants.

B. HCL + KOH——-> KCL+H2O

acid base

So, this is an acid-base neutralization reaction.

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.
