Construction of a voltaic cell Consider a cobalt-silver voltaic cell that is constructed such that one half-cell consists of the cobalt, CoCo, electrode immersed in a Co(NO3)3Co(NO3)3 solution, and the other half-cell consists of the silver, AgAg, electrode immersed in a AgNO3AgNO3 solution. The two electrodes are connected by a copper wire. The CoCo electrode acts as the anode, and the AgAg electrode acts as the cathode. To maintain electric neutrality, you add a KNO3KNO3 salt bridge separating the two half-cells. The half-cell is a chamber in the voltaic cell where one half-cell is the site of the oxidation reaction and the other half-cell is the site of the reduction reaction. Type the half-cell reaction that takes place at the anode for the cobalt-silver voltaic cell. Indicate the physical states of atoms and ions using the abbreviation (s), (l), or (g) for solid, liquid, or gas, respectively.

catya your not at all which answer i've seen you do this on another question!

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.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
