Can someone give me the anwsers to my chemistry worksheet. and there one more that isn’t in the picture and it’s nh3

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)]

What conclusion can you draw from this experiment about the components of the black ink?
