3. Will has an aquarium with water, plants, and fish that eat the plants. It is sealed so no material can get in or out, and has glass sides that allow sunlight to come in. The aquarium can also be
covered to prevent light from entering.
The amount of carbon in the aquarium's water started out high. Now, the amount of carbon in
the water is decreasing. Is the aquarium now in sunlight or is it covered? What is happening to
the number of energy storage molecules in the plants and fish as a result?

for points guys

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
