1. (7 points) A 750.00 gram lead block absorbs heat to raise its temperature from 20.0 degrees Celsius to 135.0 degrees Celsius. Using the table above, find the amount of heat energy in Joules that was required. Show your work.

That depends on what kind of environ meant it is in  in space it has the same force that was applied when the velocity was gained

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.
