Acalorimeter contains 195 g of water at 20.4 °c. a 37.8 g sample of an unknown metal is heated to 133 °c and placed
into the water in the calorimeter. the final temperature of the metal and the water are 24.6°c. what is the specific heat
of the metal?
.600kcal
.400kcal
.200kcal

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.

Ibelieve the answer is d. macula  hope my answer has you : )
