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 acid-base 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)
