International Baccalaureate IB Chemistry
5.1.1 Using chemical equations to determine ratios
Chemical equations show the ratio of reactants and products in a reaction. Deduce chemical equations when reactants and products are specified. Include the use of state symbols in chemical equations.
5.1.2 Mole Ratios: Mass, Vol, Conc
The mole ratio of an equation can be used to determine the masses and/or volumes of reactants and products and the concentrations of reactants and products for reactions occurring in solution. Calculate reacting masses or volumes and concentrations of reactants and products.
5.1.3 Limiting reactant and theoretical yield
The limiting reactant determines the theoretical yield. Identify the limiting and excess reactants from given data. Distinguish between the theoretical yield and the experimental yield.
5.1.4 Percentage yield
The percentage yield is calculated from the ratio of experimental yield to theoretical yield. Solve problems involving reacting quantities, limiting and excess reactants, theoretical, experimental and percentage yields.
5.1.5 Atom economy
The atom economy is a measure of efficiency in green chemistry. Calculate the atom economy from the stoichiometry of a reaction.
