Mark as brainlist please

A fire extinguisher is an active fire protection device used to extinguish or control small fires, often in emergency situations. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the expertise of a fire brigade. Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an agent which can be discharged to extinguish a fire. Fire extinguishers manufactured with non-cylindrical pressure vessels also exist but are less common.

Answer 2

Soda acid fire extinguisher contains an acid in a plastic bottle and solid sodium hydrogen carbonate outside it. On striking the fire extinguisher against the hard surface the glass bottle breaks and the acid mixes with sodium hydrogen carbonate. The following reaction occurs:-

2NaHCO3 + H2SO4------- Na2SO4 + 2H2O + 2CO2
