If one kilogram of hydrogen is converted to helium, how much energy will be generated? A) 9*10¹⁶ J B) 3*10⁸ J C) 6.3*10¹⁴ J D) 2.2*10⁶ J E) 3.2*10⁷ J

Question

Quizplus · Accepted Answer

The conversion of one kilogram of hydrogen to helium releases 6.3 x 10^14 J of energy, as given by Einstein's famous equation E=mc^2, where m is the mass difference between the reactants and products, and c is the speed of light. The mass difference between one kilogram of hydrogen and helium is approximately 0.007 kg, which when multiplied by the speed of light squared gives the energy released as 6.3 x 10^14 J.
