## Energies of Liquid Hydrogen Exploding and Expanding

The dihydrogen cation consists of 2 electrons(leptons (-1 e) + (-1 e) = -2 e) and 1 proton(uud = (+2/3 e) + (+2/3 e) + (-1/3 e) = +1 e), so where does all of the extra energy during a violently explosive exothermic chemical reaction involving dihyrdrogen cation fuel come from? Do you suppose the … Continue reading Energies of Liquid Hydrogen Exploding and Expanding
