If a running system has a total change in heat of 295 joules, and it's running at a temperature of 402 kelvin, what is the entropy?

a.0.981 joules/kelvin

b.0.733 joules/kelvin

c.0.618 joules/kelvin

d.0.681 joules/kelvin

\[S = \Delta Q / T\] where S - entropy, Q heat and T temperature \[S = 295/402 = 0.733 \]
SO IT'S B 

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
