Calculate the delta H reaction for the combustion of glucose (C6H12O6) using delta H(f knot) values. Calculate the delta H(f knot) of glucose to be used in the above calculation using the following information. (must be calculated, not looked up).
6CO2(g) + 6H2O(l) = C6H12O6(s) + 6O2(g) Delta H (rxn)= 2826 kJ
