A) The enthalpy of combustion for C6H12O6(s) is -2830kj/mol.

a. Write a balanced equation for the combustion of C6H12O6 in air.

b. Using the delta Hac values and the given heat of combustion calculate the standard enthalpy of atom combination Delta H ac of C6H12O6.

B) Calculate the delta H rxn for each of the following equations:

a. Fe2O3(s) + 2Al(s)---->AL2O3(s) + 2Fe(s)

b. 3SiO2(s) + 4Al(s)----->2Al2O3(s) + 3Si(s)

C) Which of those reactions produces the most heat per gram of aluminum consumed?
