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 it won't react with moist air (eliminating first option).
• No information about explosion on shaking (eliminating second option).
• Fire rating of 3 (high flammability) implies keep away from flames.
• Substantial vapor pressure means not stored under high pressure (eliminating fourth option).

Answer:

Benzene must be kept away from flames.
