A decomposition reaction produces multiple products from a single reactant.
Combustion reactions are the combination of some compound with oxygen to make oxides of the other elements as products (although nitrogen atoms react to make N2).
The solution of Ba(OH)2 will have the lowest freezing point. This is because it dissociates into 3 ions, one Ba and 2 OH, which is more than any of the others. Freezing point depression is a colligitive property of water that depends, in part, on the number of ions.
