Using the two cell reduction potentials shown for their corresponding reaction, calculate the cell potential for a voltaic cell made from these two systems. (HELP ASAAAP) A)

1.68 V

B)

0.78 V

C)

–1.68 V

D)

–0.78 V

multiply the first equation by 3 to cancel the electrons in both equations

then combine both equations

then minus both cell potentials which equals 0.78 V

I'm not sure though

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.
