Determine the energy released per kilogram of fuel used. given mev per reaction, calculate energy in joules per kilogram of reactants. consider 1 mole of tritium plus 1 mole of deuterium to be a mole of “reactions” (total molar mass = 5 grams).

Imagine that you push on a large rock. at what point does your effort change the rock’s mechanical energy?

Why is it possible for different microorganisms to extract energy not only from carbohydrates and other biological molecules but from a large variety of substances?
