Another way to produce energy is by burning natural gas, which is mostly methane (CH4). The reaction
CH4(g)+2O2(g)?CO2(g)+2H2O(g)
shows the combustion of methane. Assuming complete combustion, what mass of methane is needed to produce the same amount of energy as the fusion reaction in Part A?

The following table provides standard enthalpies of formation for methane (CH4), carbon dioxide (CO2), and water (H2O).

Substance ? H?f (kJ/mol)
CH4(g) -74.8
CO2(g) -393.5
H2O(g) -285.83

THIS IS "PART A"
The sun produces energy via fusion. One of the fusion reactions that occurs in the sun is
4 1/1H?4/2He+2 0/1e
How much energy in joules is released by the fusion of 2.38g of hydrogen-1?
Express your answer to three significant figures and include the appropriate units.

?E = ?1.47 10^12 J
