Transcript

  • 1. 2.1/2.2 NotesParker Nolan
  • 2. Pure SubstancesPure Substance:Matter that always has Every sample of a givenexactly the same substance has the samecomposition properties because a substance has a fixed, uniform composition. Examples: Table salt and table sugar
  • 3. ElementsElement: A An element has a substance that fixed composition cannot be broken because it contains down into simpler only one type of substances. atom. An atom is the smallest particle of an element.
  • 4. Compounds Compound: A compound A substance that is always contains made from two or two or more more simpler elements joined substances and in a fixed can be broken proportion. down into those simpler Example: Silicon dioxide
  • 5. Mixtures The properties of a mixture are less consistent than theThe properties of properties of a substance. a mixture can vary because the composition of Mixtures can be a mixture is not classified by how well fixed. the parts of the mixture are distributed throughout the mixture.
  • 6. Heterogeneous Homogenous In a heterogenous mixture, the parts of a In a homogenous mixture are noticeably mixture, the substances different. are so evenly distributed that it is difficult to distinguish oneGreek: substance from another.Hetero means differentGenus means kind
  • 7. Colloid When substances A colloid dissolve and form a contains some homogenous mixture, particles that the mixture that forms is are called a solution intermediate inions Solutions size between the small A suspension is a particles in a heterogenous mixture solution and the that separates into larger particles layers over time. in a suspension
  • 8. Physical Properties - ViscosityThe tendency of a liquidto keep from flowing,the resistance to flow, is The viscosity of a liquidviscosity. usually decreases when heated.The greater theviscosity, the slowerthe liquid moves.
  • 9. DistillationA process that Practical use:separates the Providing water forsubstances in a solution submarinesbased on their boilingpoints
  • 10. FiltrationA process that Practical:separates the materials A strainerbased on the size oftheir particles.
  • 11. EvaporationA process used to Property:isolate a solid Solubilitydissolved in a liquid.
  • 12. FlammabilityA materials ability toburn in the presence ofof oxygen.Sometimes, not adesirable property
  • 13. Reactivity how readily a substance combines chemically with other substances.Low reactivity: Nitrogen
