A large punch bowl holds 3.99 kg of lemonade (which is essentially water) at 20.5 °C. A 0.0550-kg ice cube at -10.2 °C is placed in the lemonade. What is the final temperature of the system and the amount of ice (if any) remaining? Ignore any heat exchange with the bowl or the surroundings.

Divide 108.2 x 10^6 into 1.5 x 10 and the result will be in au (astronomical units)

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.
