calculate the enthalpy change for the following (unbalanced equation) assume all reactants and products are in their standard states

Question

Fe2O3(s)+Al(s)---> Fe(s)+Al2O3(s)

please answer me as soon as possible.

Answer 1

Balance the equation.
deltaHrxn = (delta H products)-(delta H reactants).
For delta H, look up delta H_o^f in your text.

Answer 2

I should have written
delta H_f^o

Answer 3

okay say you have delta Hfstandard but it is only for Cu2O and your equation is 2 Cu2O -> 4 Cu + O2 then what do you do to find delta S of the reaction?
