1. Last Minute Review Warm-up
A science class is conducting an experiment that produces noxious fumes. Because of inadequate ventilation, some students begin to feel nauseated and dizzy. The first response should be to—
Neutralize the acid that is reacting to produce the noxious fumes
Carry the reactants outside, away from other students
Leave the room and go to an area with fresh air
Spray the reaction with a fire extinguisher
Label the following as intensive or extensive.
a. boiling point b. mass c. density d. hardness
3. Label the following as an element, compound, homogeneous mixture or heterogeneous mixture.
oxygen gas b. oil and water c. pure water
d. tea dissolved in water e. iron and sulfur
4. Label the following as a physical or chemical change.
