Answer 1

Explanation:

rocket fuel which reacts to give al2o3 and fe. No other reactants and products are involved. On complete reaction of 1 mole of fe2o3, 200 units of energy is released. (i) write a balance reaction representing the above change. (ii) what should be the ratio of masses of fe2o3 and al taken so that maximum energy per unit mass of fuel is released. (iii) what would be energy released
