DESCRIPTION
91. Solving a chemistry problem
Calculate the standard heat of formation of a compound from simple substances, if its heat of combustion is known at T = 298 K and a pressure of 1.0133 * 105 N / m2. Assume that the products of combustion are oxides CO2 (g), H2O (g) and N2. The heat of combustion of simple substances. C graph O2=CO2 (g) -393.795*106 J/kmol; H2 1/2 O2=H2O -286.043*106 J/kmol
6. (C2H6O2 (l) ethylene glycol) ΔHburn. = -1180.315 J/kmol
