Question 5 • *26-27 CFISD TX-Chemistry A CR
A fire rating of 3 indicates a serious fire hazard, and benzene’s substantial vapor pressure means it can readily produce flammable vapor. Therefore, it must be kept away from flames. A reactivity rating of 0 means benzene is normally stable, so the claims that it reacts readily with moist air or explodes when shaken are not supported.
