In older soda/ acid extigushers, it generated carbon dioxide gas that propelled water from the extinguisher. In modern dry chemical extinguishers, it is the extiguishing agent- the same CO2 gas cuts off the oxygen to the fire.

The function is to fight a fire which will either extinguish the fire or to fight it long enough to allow safe passage from the location - The main and most important is to use the correct extinguisher and to leave the area if the extinguisher is not impacting on the fire.
Yes. Depending on the type of fire and the type of extinguisher, you may simply spread the fire (which is bad enough) or you might actually cause more damage (trying to put out a sodium fire with a water based extinguisher, for example).
To put out a sodium fire, you can use a Class D fire extinguisher specifically designed for metal fires. Never use water, as it can react violently with sodium and worsen the situation. Additionally, you can smother the fire with sand or dry powder to deprive it of oxygen.

Class D Class D fire extinguishers are used for various types of flammable metals. A class D fire extinguisher can contain sodium chloride, graphite, or copper powder. A sodium chloride fire extinguisher would be used on metals containing magnesium, sodium, potassium, and sodium-potassium alloys. Copper and graphite fire extinguishers would be used for lithium and lithium alloy fires.
