The specific heat of copper is 0.385 J/g°C. Which equation is used to calculate the amount of heat needed to raise the temperature of 0.75 g of copper from 7°C to 29°C?

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.
