A small atomic bomb releases energy equivalent to the detonation of 20,000 tons of TNT; a ton of TNT releases 4x10^9 J of energy when exploded. Using 2x10^13 J/mol as the energy released by fission of 235U, approximately what mass of 235U undergoes fission in this atomic bomb? Explain in detail how you arrived at the answer.
Assuming that sucrose is produced by the reaction: 12CO2(g)+11H2O(l) yields C12H22O11(s) 12O2(g); delta H=5640kj calculate the percentage of sunlight used to produce the sucrose- that is, determine the efficiency of photosynthesis.
