• Show ratio of reactants and products

• Deduce balanced equations, including state symbols, from named reactants and products

• Determine masses, volumes, concentrations

• Use balanced equations for reacting quantity calculations

• Determines theoretical yield

• Identify limiting and excess reactants from given data

• (Experimental yield / Theoretical yield) × 100%

• Solve problems involving theoretical, experimental, and percentage yields

• Measure of green chemistry efficiency

• Calculate atom economy and link low atom economy to waste
