How do I balance the following equation?FeS2O3 + H2 ---> H2O

Can someone me with questions 12 and 13 plz.

650.j is the same amount of energy as? 2720cal1550cal650.cal2.72cal

Consider the reaction: 2al(s) + fe2o3(s) → al2o3(s) + 2fe(s) the δhf for fe2o3(s) = -824.3 kj/mole. the δhf for al2o3(s) = -1675.7 kj/mole. finish the equation. δhrxn = [(1)( kj/mole) + (2)( kj/mole)] - [(1)( kj/mole) + (2) ( kj/mole)]
