Balance Chemical Equations
 Explain what the law of conservation of mass is. Write and balance equations for chemical reactions using abbreviations (s,l,g,aq) where appropriate. (D2)
Types of Reactions
 Classify, write formulas, and predict products for any of the following types of reactions: synthesis, decomposition, single replacement, double replacement, combustion, and acidbase neutralization (D3)
Energy in Reactions
 Classify reactions as exothermic or endothermic, explain the connection between energy changes and bond breaking/forming. Write equations for chemical reactions which involve an energy term. (D4)
Stoichiometry
 Perform calculations involving reactions using any of the following
 number of molecules
 moles
 mass
 gas volume at STP
 solution's concentration and volume (e.g. titrations) (D5)

Excess quantities
 Perform calculations involving a limiting reactant. Calculate percentage purity and percentage yield. (D5)
