  1. If there only about 100 types of elements in the world, why are there so many different kinds of matter? 60 140 130 120 40 50 30 10 70 8 7 6 5 9 4 3 2 0 180 80 20 90 160 150 170 100 110 1 Seconds Left:

  2. Elements can combine in many different ways to form many different types of matter.

  3. Describe the difference between a mixture and a compound. 60 140 130 120 40 50 30 10 70 8 7 6 5 9 4 3 2 0 180 80 20 90 160 150 170 100 110 1 Seconds Left:

  4. Compounds are chemically combined, mixtures are not.

  5. Define: Solute Solvent Solution 60 140 130 120 40 50 30 10 70 8 7 6 5 9 4 3 2 0 180 80 20 90 160 150 170 100 110 1 Seconds Left:

  6. Solution – homogeneous mixture where a solute is dissolved in a solvent Solute – the matter that gets dissolved Solvent – the matter that does the dissolving

  7. Which kind of mixture is sometimes difficult to distinguish from a compound? Why? This screen will disappear in 3 minutes. 70 120 50 130 60 30 40 10 140 8 7 6 5 9 4 3 2 0 180 20 90 160 150 170 80 100 110 1 Seconds Remaining.

  8. Homogeneous mixtures because the mixtures are the same throughout

  9. Define the terms: Element Mixture Compound Molecule 60 140 130 120 40 50 30 10 70 8 7 6 5 9 4 3 2 0 180 80 20 90 160 150 170 100 110 1 Seconds Remaining:

  10. ELEMENT – matter made of only one type of atom; a pure substance MIXTURE – a combination of different types of matter in no fixed proportion; can be physically taken apart COMPOUND – a combination of different types of matter in specific proportions; must be chemically taken apart MOLECULE – the smallest part of a compound that has all the properties of that compound
