Question

A mixture of 27% powdered aluminum and 73% iron (III) oxide is commonly called what? Answer Zieglar-Natta catalyst Luminol Lith-X Thermite What is the name of a substance that self-ignites without exposure to an ignition source? Answer Corrosive solid Pyrophoric Explosive Flammable liquid Which of the following elemental materials are not pyrophoric when they are in dust, powdered, or finely divided form? Answer Aluminum Zinc Titanium Copper What are two common fire extinguishers that are ineffective on alkali metal fires? Answer Carbon dioxide and water Dry powder fire extinguishers and water Carbon dioxide and dry chemical Halon and carbon dioxide Is the application of carbon dioxide recommended for extinguishing combustible metal fires? Why, or why not? Answer Yes, because the hot magnesium reacts with the carbon dioxide to self extinguish the flames. Yes, but you need to follow with a course of dry chemical extinguisher agents. No, because the hot magnesium reacts with the carbon dioxide. No, because you can never get close enough to any size fire of this sort to adequately mitigate the situation.
