Chemistry & Chemical Reactivity
The average energy output of a good grade of coal is 2.6 × 107 kJ/ton. Fission of 1 mol of 235U releases 2.1 × 1010 kJ Find the number of tons of coal needed to produce the same energy as 1 lb of 235U. (See Appendix C for conversion factors.)
Interpretation: The number of tons of coal is equal to the energy of uranium.
Concept introduction:
Nuclear fission is the splitting of the nucleus of a radioactive atom into smaller nuclei. Huge quantity of energy is released during fission.
Conversion of pound to gram is as follows:
Given information is as follows:
Molar mass of
