The anode is the negative electrode and so will be donating electrons to assist in this chemical reaction occuring. All reactions accept electrons as reactants. The key issue is the reduction potential Eo (+1.8V). This is greatest for the reaction:
Co3+ + e -> Co2+
Therefore this reaction has the greatest tendency to occur.
Electric
current passes through a filament of an incandescent bulb, thereby increasing
it temperature. When current flows, it contains electrons through the filament
to produce light. Typically, incandescent light bulb consists
of a glass enclosure that contains tungsten filament. The glass enclosure
contains either a vacuum or an inert gas that serves as the filament protection
from evaporating. Incandescent light bulbs contain a stem attached at to its
base to allow the electrical contacts to run through the envelope without gas
or air leaks.
A substitution is a mutation that exchanges one base for another. This can include a change in a single chemical letter. ex. changing a to g or in your case g to a. I believe the correct answer should be B.
Answer:
Cobalt (Co)
Explanation:
3d^7 is the location of Cobalt's last electron.
