4. Which of the following describe a chemical change? (Select all that apply)
A. Melting of ice
B. Evaporation of alcohol when a table is wiped with an alcohol swab
C. Burning of firewood
D. Rusting of iron

1. Magnesium-B
2. Salt water-C
3. Blood- E
4. Carbon dioxide-A
5. Soil sample- D
A. Compound
B. Element
C. Solution
D. Heterogeneous mixture
E. Suspension
6. Which of the following illustrations best illustrate an element, a compound, and a
mixture. Provide an explanation for your choices.
C- Element. The illustration shows everything made of the same type of
particle. A-Compound all the particles have the same configuration and ratio
B. Mixture. The configuration is non-uniform and the ratio is not fixed
7. Describe a method to separate the substances in a solution.
One way to separate substances is to take them to a boiling point. Boiling causes the
substance to separate from the mixture solution. Separating a solution this way is referred
to as distillation.
8. Distinguish between a saturated and an unsaturated solution.
Solutions with a maximum solute concentration is known as saturated and all other
solutions which have lower concentrations are said to be unsaturated
9. Match the following:
1. Sodium chloride, NaCl -D
2. Oxygen, O2 - C
3. Methane, CH4 - E
4. Lithium - A
5. Air- B
