2. Describing Chemical Reactions
Chemical equations
Words or formulas? Both can mean the same, but need for specificity exists!
Symbols
 read as yields
Parenthetical symbols for states of reactants and products
Delta over arrow means heat added
Symbol/s over arrow mean catalysts
Coefficients: numbers added to indicate mole ratios for balancing eqns.

4. Reactions in aqueous solution
Reality check: most reactions occur in solutions…our world is largely aqueous!
Complete/total ionic equation: all ions present in the ionic compounds of both reactants and products
Spectator ions: those not involved in the formation of a product (typically a precipitate…insoluble)
Net ionic equation: this involves only those ions which form a product or precipitate in a reaction
Realization: water can be the product formed!
How to predict formation of a product? SOLUBILITY RULES!
