What is the energy (in joules) evolved when 1 mol of helium-4 nuclei is produced from protons and neutrons? How many liters of ethane, C2H6(g), at 25°C and 725 mmHg are needed to evolve the same quantity of energy when the ethane is burned in oxygen to CO2(g) and H2O(g)? See Table 20.3 and Appendix C for data.
