In the process of photosynthesis, plants use carbon dioxide (co2), water (h2o), and light energy to produce a sugar (c6h12o6) and oxygen (o2). in the process of aerobic respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. the chemical equations that describe these reactions look like this:

6co2 + 6h2o + light = c6h12o6 + 6o2 c6h12o6 + 6o2 = 6co2 + 6h2o + energy

how do these equations explain why the total amount of o2 and co2 remains the same?

since electrons are negative the answer is neagtaive

what are the statements

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.
