Agenda

Agenda

  • Review mixtures and solutions orally

  • Notes on solutions (1 slide)

  • Review Video.

  • Physical Properties (2 slides)

  • Pop Quiz!

  • Homework: On the whiteboards.


Review don t copy this down

REVIEW (don’t copy this down)

  • Matter

    • Anything that has MASS and takes up space (VOLUME)

  • Mixture

    • combination of 2 things not chemically bound together

  • Solution

    • a homogenous mixture of 2 substances evenly distributed

      • Solute (ex: sugar)

      • Solvent (ex: water)


Thursday 10 7 2010 do now

  • Notes begin on the next slide.

  • Remember: you are responsible only for what is BOLDED and UNDERLINED.


10 7 notes

10/7 Notes

*Solutions

  • Saturated solution – the max amount of solute has been dissolved

  • Supersaturated solution – more than the max amnt has been dissolved. Precipitate is formed at the bottom of the cup.

Physical properties

*Physical Properties

  • Characteristics of matter that can be observed using your senses; the substance is NOT changed into something different.

  • Used to separated mixtures.

  • Include:

    • Color

    • Viscosity (resistance of a liquid to flowing)

    • Luster (shininess)

    • Ductility (ability to bend/stretch w/o cracking)

    • Density

    • What is a physical property of your lab desk?


Density

*DENSITY

  • How much matter is in a certain volume of a substance

  • Equation:D = m/v

    Density = mass/volume

  • SI Units:g/cm3

  • NOTE:1 cm3 = 1 mL

  • Liquid water has a density of 1 g/cm3.

    • If something is MORE dense (ex: brick), it sinks.

    • If something is LESS dense (ex: ice), it floats.


Both the sponge and the brick have the same volume which is more dense

Both the sponge and the brick have the same volume. Which is MORE DENSE?


Pop quiz 15 points

POP QUIZ!!!(15 points)

  • You may use your OWN notes.

  • 15 questions – each worth 1 point.

  • When you are done, raise your hand and I will collect the quiz from you.

  • In your textbook:

    • Pg. 26, # 5
