The enthalpy of formation (Delta. Hf) for C6H12O6(s) is –1,273.02 kJ/mol, Delta. Hf for CO2(g) is –393.5 kJ/mol, and Delta. Hf for H2O(l) is –285.83 kJ/mol. What is Delta. Hf for O2(g)?
✔ exactly 0 kJ/mol

Which equation should be used to calculate Delta. Hrxn for this reaction?
(-393.5kJ/mol + (-285.83 kJ/mol))-(-1,273.02 kJ/mol)

-1,273.02 kJ/mol - ((6 mol)(-393.5 kJ/mol) + (6 mol)(-285.83 kJ/mol))
((6 mol)(-393.5 kJ/mol) + (6 mol)(-285.83 kJ/mol)) - (1 mol)(-1,273.02 kJ/mol)

What is Delta. Hrxn for this reaction?
