LEARNING OBJECTIVES

Use the concept that p ∝ n to determine the partial pressure of a particular gas in a mixture.
Determine by experiment the volume of a mole of gas at STP.
Develop and use the ideal gas law equation to determine the number of moles in a sample of gas not at standard condition.
Relate the molar concentration (molarity) of a solution to the number of moles and volume of the solution.
Use information regarding molarity and volume to determine the number of moles of a reactant or product in a given volume of solution.
Sketch energy bar graph diagrams to represent energy storage and eventual transfer in exothermic and endothermic reactions.
Extend the use of the BCA table, first used in situations where the mass of reactant or product was known, to cases involving volume of a gas or solution or energy of reaction.
