6. Among the substances that react with oxygen and that have been considered as potential rocket fuels are diborane Bho, produces B2O3(s) and H2O(g)], methane (CH4, produces CO2(g) and H2O(g)], and
hydrazine N2H4, produces N2(g) and H2O(g)]. On the basis of the heat released by 1.00 g of each
substance in its reaction with oxygen, which of these compounds offers the best possibility as a rocket fuel?
The AH; of B2H6(g), CH4(g), and N2H4(1) may be found in Appendix G.
