Front 12

Mechanical Mixture

Back 12

a heterogeneous mixture; in a mechanical mixture at least two substances are visible

Front 13

Front 18

WHMIS

Back 18

(Workplace Hazardous Materials Info System) symbols found on hazardous products that identify the type of danger associated with the product and that provide information on safe handling

Front 19

Particle Theory

Back 19

A theory used to explain matter and heat transfer. It suggests that all matter is made up of tiny particles too small to be seen. These particles are constantly in motion because they have energy. The more energy they have the faster they move.

Front 20

Homogeneous Material

Back 20

A mixture that is the same throughout; all samples taken will have the same properties

Front 21

Solutes

Back 21

A substance that is dissolved in a solvent to form a solution

Front 22

Dilute Solution

Back 22

solution with room for more solute to be dissolved in it

Front 23

Saturated Solution

Back 23

A solution that contains the maximum amount of solute that the solvent can dissolve at the given temperature

Front 24

Ceramics

Back 24

A material manufactured by heating minerals and rocks; ceramics include pottery, bricks, cement, and glass

Front 25

PH Scale

Back 25

A gauge ranging 0 (strongly acidic) to 14 (strongly alkaline), used to express the acidity or alkalinity of a solution

Front 26

Hard Water

Back 26

Water that contains certain dissolved substances, such as magnesium, calcium and sulfur

Front 27

Solubility

Back 27

The maximum amount of a particular solute that can be dissolved in a particular solvent at a given temperature
