Physical Science Final Exam Study Guide
1 Physical Science Final Exam Study Guide I. Chemistry 1. What is the difference between a homogeneous mixture and a heterogeneous mixture? 2. List 2 examples of a homogeneous mixture and 2 examples of heterogenous mixtures. 3. List 2 examples of a pure substance and 2 examples of a mixture. 4. Where are metals, nonmetals, and metalloids located on the periodic table? Be specific! 5. List 2 formulas for an element and 2 formulas for a compound. 6. Compare these phases: Particle attraction? (how tightly are their molecules packed?) Particle motion? (How do they move/how much do they move within the substance?) Explain the gain or loss of heat when going to next So, what does this gain or loss of heat do to the attraction of the particles? Solid Liquid Gas 7. Phase changes: Please complete this table: Phase change? (solid to liquid to gas, etc.) Is energy taken in (endothermic) or released (exothermic)? Melting Vaporization Condensation Freezing 2 8.
14. Explain how you could separate a mixture using solubility, density, boiling point, and magnetic properties. 15. Please complete this table: Metal Nonmetal Metalloid Definition, if necessary State of matter at room temperature Density (high or low) Melting points are normally… Boiling points are normally… Lustrous? Conductive? Ductile?
