molecule.
b. it is nonpolar, because the bond polarities cancel each other out in
a linear molecule.
o
c. it is polar, because the bond polarities add together in a bent
molecule.
o

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)]
