			Packet #1 AP Chem
				This packet is due in on the first day of school.  All work must be included for any problems requiring calculations.  Do not just submit answers.
	The Nature of Matter Standard 1: The student understands that all matter has observable, measurable properties. (SC.A.1.4) 1. knows that the electron configuration in atoms determines how a substance reacts and how much energy is involved in its reactions. 2. knows that the vast diversity of the properties of materials is primarily due to variations in the forces that hold molecules together. 3. knows that a change from one phase of matter to another involves a gain or loss of energy. 4. experiments and determines that the rates of reaction among atoms and molecules depend on the concentration, pressure, and temperature of the re-actants and the presence or absence of catalysts. 5. knows that connections (bonds) form between substances when outer-shell electrons are either transferred or shared between their atoms, changing the properties of substances.
		1.  Write up one question along with a solution for each of the following topics: a.  Chemical Formula problem b.  Isotope problem c.  Chemical Reaction problem d.  Mass Percent problem e.  Empirical Formula problem f.  Limiting Reactant problem g.  Percentage Yield problem h.  Density problem
