1.)The formation of one mole of TiBr3, from the elements (Ti and Br2) librates 132 kcal. Find the heat produced in making 55.6 grams of TiBr3.

2.) How much energy is liberated when 0.100 mole of H2 at 25 degrees C and ! atmosphere is combines with enough O2 (g) to make liquid water at the same conditions.

3.) a reaction between Fe2O3. ferric oxide, and metallic alluminum. The reaction produces white-hot, molten iron in a few seconds
Given:  2Al= 3/2 O2----> Al2O3 + 400 kcal
        2 Fe + 3/2 O2---> Fe203+ 200 kcal

4.) How much energy is released in the manufacture of 1.00 kg of iron by the thermite reaction mentioned in problem 4?'


PLEASE HELP ME WITH THEM I DON'T GET IT!!

You need to attempt them yourself first.
