According the equation: 2H, O+ electricity → 2H2 + O2 A) An electrolytic cell, because it absorbs energy.

B) A voltaic cell, because it releases energy. C) A voltaic cell, because it absorbs

energy.

D) An electrolytic cell, because it releases energy.

E) All of them

A) An electrolytic cell, because it absorbs energy.

Explanation:

The major difference between an electrolytic cell and a voltaic cell is that, in an electrolytic cell, there must be input of energy from outside (a cell) to drive the non spontaneous reaction while in a voltaic cell, the reaction proceeds on its own and releases energy which could be harnessed to do work.

Hence, considering the equation; 2H2O+ electricity → 2H2 + O2 , energy is supplied as electricity in order for the process to take place. This is an example of an electrolytic cell.

the correct answer is answer a. a mixture

no other options make sense

hope this

have a great day : )

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.
