C57H104O6(l)+O2(g) CO2(g)+H20(g) THE COEFFICIENTS OF PEANUT COMBUSTION
Calculate the delta H for the reaction N2H4(l)+ O2(g) --> N2(g) + 2H20(l) Given the following data: 2NH3(g) + 3N20(g) --> 4N2(g) + 3H20(l) N20(g) + 3H2(g) --> N2H4(l) + H20(l) 2NH3(g) + 1/2O2(g) --> N2H4(l) + H20(l) H2(g) + 1/2O2(g) --> H20(l)
