A

4. A compound is added to a solution of hydrochloric acid, and the solution is observed to see if a reaction takes place. Chemical ___________ is being tested.

A. acidity B. reactivity C. durability D. solubility

BChemical reactivity tests determine if a substance

reacts with certain chemicals. One typical chemical reactivity test involves adding the substance to a

solution of acid to see if a chemical reaction occurs. Other common tests involve observing the reaction

between the unknown substance and oxygen, water, or salts.

5. Which of the following items would have the lowest density?

A. A 2 cm3 block of lead with a mass of 11 grams B. A 12 cm3 block of wood with a mass of 3 grams C. A 6 cm3 block of ice with a mass of 4 grams D. A 12 cm3 block of aluminum with a mass of 2 grams

D. Density refers to the mass per volume of an object.

A 2 cm3 block of wood with a mass of 11 grams has a density of 5.5 g/cm3.

A 12 cm3 block of wood with a mass of 3 grams has a density of 0.25 g/cm3.

A 6 cm3 block of ice with a mass of 4 grams has a density of 0.6667 g/cm3.

A 12 cm3 block of aluminum with a mass of 2 grams has a density of 0.1667 g/cm3.

Therefore, a 12 cm3 block of aluminum with a mass of 2 grams has the lowest density.
