How to solve for q thermochemistry
WebTo solve this problem, we assume each peanut, with an average mass of 0.73 g, is 49% peanut oil and 21% starch; the remainder is noncombustible We further assume peanut oil is palmitic acid, C16H32O2, with an enthalpy of formation of 848.4 kJ/mol. Starch is a long chain of C6H10O5 units, each unit having an enthalpy of formation of 960 kJ. http://chschem.weebly.com/uploads/2/7/1/6/2716189/thermo_example_problems.pdf
