Consider the following electrochemical cell: Co (s) | Co2 (aq, 1.00 M) || Pb2 (aq, 1.00M) | Pb (s) What will the potential (in volts, V) of the cell be if it is allowed to run until the concentration of the transition metal in the cathode is 0.45 M

the temperature of the gas, in k, not celsius.

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? "
