mixture?

compounds?
• If I am looking at B10, B11 and B12, how
5. • If I have dissolved 3.5 mL of HCl in a
solution containing 165 mL of H2O,
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.

similar?
6. • KNO3 = element, compound or mixture?

mixture?

heterogeneous mixture? Why?
• What is the valence of Na and what
family does this element belong to?
• What is the valence of Barium?

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.
