* Incorrect. What is the heat of formation of elements in their standard states? Did you use the correct equation of products minus reactants? The amino acid glycine, C2H5NO2, is one of the compounds used by the body to make proteins. The equation for its combustion is 4C2H5NO2(s) + 902(g) + 8C02(g) +10H20(1) +2N2(0) For each mole of glycine that burns, 973.49 kJ of heat is liberated. Use this information, plus values of AHF for the products of...
