Question

Match the following substances with the best classification:a. Magnesiumb. Salt waterc. Bloodd. Carbon dioxidee. Soil sample1. Compound2. Element3. Solution4. Heterogeneous mixture5. Suspension1. Describe a method to separate the substances in a solution.2. Distinguish between a saturated and an unsaturated solution.

Answer 1

Magnesium is an Element

Salt water is a Solution

Blood - Suspension because it contains indissoluble components in a solvent

Carbon dioxide - Compound because it has two elements which cannot be separated by physical means

Soil sample is aHeterogeneous mixture

2. You can separate substances in a solution by

Evaporation here the solvent with a smaller boiling point evaporates leaving the solute

3. A Saturated solution is the solution where no more solute can be dissolved while an Unsaturated solution has the ability to dissolve the solute in the solvent.
