It depends upon the type of chemical that is burning, but frequently it is safe to use a dry-chemical powder (DCP), or an ABC type of extinguisher.
However, boiling grease fires may need a Class K extinguisher and flammable metals (aluminum, magnesium, lithium, etc) may need a Class D extinguisher.
There are numerous ways, and the best choice may depend upon the chemical that is burning.
If it is an "ordinary combustible", such as rubber or plastic, use a Class A extinguisher, which is often just water or foam.
If it is a flammable liquid chemical, you can use a Class B extinguisher.
For Class D flammable metals (e.g., magnesium, lithium, aluminum) you would use a Class D extinguisher or other type of materials recommended by the Material Safety Data Sheet (MSDS), but certainly not water.
For flaming grease fires in kitchens, the Class K extinguisher has been developed, which turns the surface of the grease to a non-flammable soap-like substance.
Class B is for flammable liquids such as cooking grease/oil, kerosene, gasoline, paint thinner, oil, etc.

Yes. They are rated for the type of fire they can be used against, and the capacity of the extinguisher.
It will put out burning fluids.
A typical restaurant would require at least one Type ABC fire extinguisher plus a Type K fire extinguisher near the kitchen (for grease and fryer fires).
Class D- Dry Chemical for fires in combustible metals such as sodium, magnesium, and potassium.
