Question

the msds for benzene indicates that it is a clear liquid that has a substantial vapor pressure. it has a health rating of 2, a fire rating of 3, and a reactivity rating of 0. it is a cancer - causing agent. based on this information, which statement about benzene is accurate? benzene readily reacts with moist air. benzene explodes if the container is shaken. benzene must be kept away from flames. benzene must be stored under high pressure.

Explanation:

• Reactivity rating of 0 means benzene is not reactive (so "Benzene readily reacts with moist air" is wrong).
• No information about explosion on shaking (so "Benzene explodes if the container is shaken" is wrong).
• Fire rating of 3 (high fire hazard) implies keep away from flames.
• Substantial vapor pressure suggests not store under high pressure (so "Benzene must be stored under high pressure" is wrong).

Answer:

Benzene must be kept away from flames.
