Objective/Warm-Up

• Students will be able to distinguish between
  types of matter.
• Convert
• 0.567 days to minutes

3
Objective/Warm-Up

• Students will be able to distinguish between
  types of matter.
• Convert
• 57050 seconds to hours
• 320 inches/minute to yards/hour

4
Objective/Warm-Up

• Students will be able to convert units and
  calculate density.

• 57050 seconds to hours
• 320 inches/minute to yards/hour

5
Matter

• Atom the smallest unit of an element that
  maintains the properties of that element
• Pure substance a sample of matter that has
  definite chemical and physical properties.

6
Pure Substances

• Element a substance that cant be separated or
  broken down into simpler substances by chemical
  means
• Symbols
• Common

7
Pure Substances

• Molecule the smallest unit of a substance that
  keeps all of the physical and chem. props. of
  that substance can be 1, 2 or atoms bonded
  together.
• Monotomic and diatomic

8
Pure Substances

• Allotrope 1 of multiple different molecular or
  crystalline forms of an element
• O and C
• Compounds a substance made up of atoms of 2 or
  more diff. elements chemically bonded.

9
Compounds

• Represented by formulas
• More classifications for compounds

10
Mixtures

• Mixture collection of 2 or more pure substances
  physically mixed together
• Proportions can vary
• Sweet tea or gold different ratios in mixtures

11
Types of Mixtures

• Homogeneous mixture something that has a
  uniform structure or composition throughout (ex
  vinegar, tea, saltwater, gasoline, syrup, air)
• Different components cant be seen

12
Mixtures

• Heterogeneous Mixture a mixture composed of
  dissimilar components
• Examples orange juice, salad, granite

13
Difference between mixtures and compounds

• Compound chemically combined
• Properties are different from components
• Components in same ratios throughout
• Mixture physically combined
• Properties are similar to components
• Components in varying ratios throughout
