Dry chemical fire extinguishers use a powder substance, such as sodium bicarbonate or monoammonium phosphate, to smother the fire and interrupt the chemical reaction. HCFC 123 fire extinguishers contain a clean agent called HFC-123, which is a halocarbon compound that extinguishes fires by removing heat and interrupting the chemical reaction. The main difference is in the extinguishing agent used, with dry chemical extinguishers being more versatile but leaving residue, while HCFC 123 extinguishers are cleaner and more suitable for sensitive equipment.
The larger fire extinguisher can be used to put out more fire, or allows you to accidentally waste some of it and still put out smaller fires.
NO!!!!! Use a Dry Chemical extinguisher

Flammable metals often require special chemicals to extinguish, assuming there are any. So, in fact, you WOULD use a "chemical extinguisher", but probably not an ordinary dry chemical extinguisher.
The b-2 has about twice the capacity of a b-1.
Depends entirely on what the chemical is.

You would not want to use a pressure water extinguisher on any electrical fire due to the possibility of electricity being conducted through the water and injuring someone. A CO2, dry chemical or "clean agent" (e.g., "Halogenated") extinguisher would be a better choice for an electrical fire, knowing that dry chemical powder will make quite a mess.
The average cost of recharging a fire extinguisher is typically between 15 to 50, depending on the type and size of the extinguisher.
True, provided that the extinguisher is the proper type. An ABC dry chemical extinguisher would be the best extinguisher to use.
ABC is the acronym for an extinguisher certified for A, B, and C type fires. A is common fuels like wood, B is for flammable liquids, and C is for charged electrical fires. DCP stands for Dry Chemical Powder, which is inside the extinguisher and is the actual fire suppressant. Basically, DCP is a type of ABC Extinguisher. You can also get extinguishers for Type D (combustible metals), Type K (kitchen), and other specialized extinguishing agents (i.e. Halon). Or you can get a Type A extinguisher, AB, B, BC, ABC, and others even!
