Transcript

  • 1. 2.1-2.2Gabriel Burson
  • 2. MixturesMixtures consist of two or more substances that canbe physically separated and are not chemicallycombined. The characteristic properties of thesubstances do not change.Heterogeneous mixture Homogeneous mixture
  • 3. ElementsElements cannot be physically or chemically brokenapart into anything else. They are the simplest form of apure substance.
  • 4. CompoundsCompounds are composed of two or more puresubstance that are chemically combined. Compoundsdo not retain to their characteristic properties and canbe separated chemically.
  • 5. AlloysAn alloy is a mixture of two or more metals.
  • 6. ColloidA colloid has particles that are mixed together, but notdissolved.
  • 7. SolutionA solution is a homogeneous mixture that is fully mixed.It has a solute and a solvent.
  • 8. DistillationA process that separates the substances in a solutionbased on their boiling points.
  • 9. FiltrationA process that separates materials based on the size oftheir particles and/or solubility.
  • 10. EvaporationA process used to isolate a solid dissolved in a liquid.
  • 11. FlammabilityFlammability is a material’s ability to burn in thepresence of oxygen.
  • 12. ReactivityReactivity is the property that describes how fast asubstance combines chemically with another.
  • 13. Chemical changesChange in color, production of gas, formation of aprecipitate.
  • 14. Give an example of a colloid
  • 15. How would you separate sugar dissolved in water and collect a sample of each?
  • 16. Is this a chemical or physical change?
  • 17. Give an example of a heterogeneous mixture
  • 18. Explain how you would calculate the density, volume, and mass of each substance within a mixture of alcohol and water
