does annyone know why this is used in A B C type fire extinquishers? how does it put out a fire? and secondly what will it react with to make more
useful chemicals?

tumadre ...here is some info on your request but leave the madre out of it......but the reply is " la tuya"......solo
Class A extinguishers are for ordinary combustible materials such as paper, wood, cardboard, and most plastics. The numerical rating on these types of
extinguishers indicates the amount of water it holds and the amount of fire it can extinguish.
Class B fires involve flammable or combustible liquids such as gasoline, kerosene, grease and oil. The numerical rating for class B extinguishers
indicates the approximate number of square feet of fire it can extinguish.
Class C fires involve electrical equipment, such as appliances, wiring, circuit breakers and outlets. Never use water to extinguish class C fires -
the risk of electrical shock is far too great! Class C extinguishers do not have a numerical rating. The C classification means the extinguishing
agent is non-conductive.
Class D fire extinguishers are commonly found in a chemical laboratory. They are for fires that involve combustible metals, such as magnesium,
titanium, potassium and sodium. These types of extinguishers also have no numerical rating, nor are they given a multi-purpose rating - they are
designed for class D fires only.

yes.....
I want to know how to (ab)use the 40 pounds of this stuff i have. will it elelectrolize in water? what if lead acetate is in the water, would it
produce leadphosphate and amonium acetate? or can I heat it with carbon? what would that produce? will it react with sodium or aluminium or sulfuric
acid, it might, it also would help if someone could give me a reason to make amonium sulfate vs. amonium aceetate; I have the 40 pounds because I set
up the fire extinquisher as a holding tank for liquid Cl2... that gives me an idea, will amonium phosphate react with liquid Cl2 under 300 psi or is
that a "warning risk of permanent bodily injury"

You can always reduce it with carbon and/or aluminum and/or magnesium and/or silica to make white phosphorous.
