same?
•Why are mixtures not “pure”?
•Name any 3 ways to separate a
mixture?
•What does having a “set ratio” mean for
compounds?

solution containing 165 mL of H
2
O,
which component of this mixture is the
solute and which is the solvent? How do
you know?
•Give an example of a heterogeneous
mixture.
•Give an example of a homogeneous
mixture.
•How are these two types of mixtures
similar?

6. •KNO
3
= element, compound or mixture?

mixture?

heterogeneous mixture? Why?

nonmetals on the P.T.? Why?

7. •A molecule is formed when two or more
atoms join together chemically. A
compound is a molecule that contains at
least two different elements.
• All compounds are molecules but not all
molecules are compounds.

Covalent Bond

8. •A pure substance
•A substance made up of atoms
from two or more different
bonded elements.
•SPECIFIC RATIO

Ionic Bond

9. •A combination of two or more
substances blended together
•No set ratio of ingredients

10. •Homogeneous: 2 or more
things evenly blended and
disappear into each other.
•Solute – Smaller quantity
•Solvent – Larger quantity
•Solution – a homogeneous
mixture

11. •Heterogeneous: 2 or more
things put together
•Individual components visible
•NO SET RATIO.
