Unit 10 Packet
Learning Objectives
- The state of a substance is based on the molecular structure, kinetic energy, and intermolecular attractions
- Describe particle arrangement and motion in the different states using the kinetic molecular theory of matter
- Gases behave in predictable ways which can be described through defined laws
- Describe the properties of gases using volume, temperature, pressure and number of particles
- Identify and use the appropriate gas law when quantitatively describing changes in gases
- Describe how ideal gases adhere to predicted changes in temperature, volume, pressure and moles
- Describe conditions where ideal gases fail
- Use the ideal gas law in stoichiometric problems that include gases at non STP conditions
- Calculate partial pressures of gases in a mixture using Dalton’s Law of Partial Pressures
- Describe how molecular mass affects effusion rates of gases
- Gas Stoichiometry
- Correlate the mole and volume of a gas at STP using molar volume
- Solve stoichiometric problems using masses, particle numbers and volumes of gases at STP
