Question

Calculate the ΔHrxn for the following reactions using the heats of formation given in the table at the end of this assignment:
a)The complete combustion of methane, CH4, producing water as a liquid.
b)The complete combustion of glucose, C6H12O6, producing water as a liquid.
c)The reaction of iron(III) oxide with carbon monoxide to produce solid iron and carbon dioxide.
d)The reaction of aluminum with Fe3O4
e)The combustion of carbon monoxide, producing carbon dioxide gas.

Answer 1

Write and balance the equation.
Then dHrxn = (n*dHf products) - (n*dHf reactants)
