Predicting Reaction Products

Predict the products, and balance each reaction.  Use the reaction type as a hint.   For reactions with a transition metal, use your periodic table to find the most likely charge on the metal in the product.

Decomposition - Many compounds decompose in predictable patterns:
Carbonates (compounds containing CO32) give off carbon dioxide and leave oxide compounds behind.
Sulfates (with SO42) give off sulfur trioxide and leave oxide compounds behind.
Hydroxides (with OH1) produce water and leave oxide compounds behind.
Chlorates (with ClO31) give off oxygen and leave chloride compounds behind.
Hydrates (with H2O) break up into water and anhydrous compounds.
Binary compounds (made of just two elements) break down into their elements.  (Don't forget about HOFBrINCl!)

Combustion - Combustion reactions always have hydrocarbons (C & H) or carbohydrates (C, H, & O) combining with pure oxygen (O2).  The products are always carbon dioxide and water.  ("Incomplete Combustion" results from a lack of available oxygen, and gives carbon monoxide as a product instead of carbon dioxide.  It can't be predicted as a likely reaction based on the reactants.)

  2. ____C10H22 + ____O2 ®
