The student is now told that the four solids, in no particular order, are barium chloride (BaCl2BaCl2), sugar (C6H12O6C6H12O6), benzoic acid (C6H5COOHC6H5COOH), and potassium bromide (KBrKBr). Assuming that conductivity is correlated to the number of ions in solution, rank the four substances based on how well a 0.20 MM solution in water will conduct electricity. Rank from most conductive to least conductive. To rank items as equivalent, overlap them.

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)]
