Consider the nuclear fusion of hydrogen into helium:

identical subatomic particles 

(a) What are the two identical subatomic particles?

(b) During this transformation, mass is lost and converted into energy, releasing 2.56 × 10⁹ kJ per mole of helium formed. How many gallons of gasoline would you have to burn to release this much energy, assuming gasoline is pure octane? Burning octane releases 5509.0 kJ/mol; the MM of octane is 114.23 g/mol; the density of octane is 0.703 g/mL; there are 3785.408 mL per gallon.

(c) How much mass was lost in grams? Note that a joule is a kg m²/s².
