Which produces the most energy? a. fusing 5 kg of hydrogen. b. passing 5 kg of water through a hydroelectric power plant. c. burning 5 kg of gasoline. d. fissioning 5 kg of uranium.

Option D

Explanation:

The energy produced by nuclear fuel i.e uranium is extensively high as the reactant enters into an unstoppable chain reaction. It is estimated that energy produces by 1 Kg of uranium is 2.5 * 10^6 times the energy produced by 1 kg of coal.  

1 kg of gasoline produces 12 kWh of energy and 1 kg of coal produces 8 Kwh of energy. Likewise 1 kg of hydrogen produces 33.33 kWh of energy and s 30 Kwh of energy is produced by 1 Kg of water. 1 kg of uranium will produce 2.4 * 10^7 kWh of electricity.  

Hence, option D is correct

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
