Explain with the help of a balanced chemical equation. how are the chemicals useful in extinguishing fire?
Answers
Answer:Soda-acid fire extinguisher contains sodium bicarbonate and sulphuric acid, which are in separate container in them. When knob of the fire extinguisher is pressed, then sulphuric acid mixes with sodium bicarbonate and produces a lot of CO

Explanation:
Answer:
CH4+2O2 ----> CO2+2H2O
Explanation:
Sodium bicarbonate, regular or ordinary used on class B and C fires, was the first of the dry chemical agents developed. In the heat of a fire, it releases a cloud of carbon dioxide that smothers the fire. That is, the gas drives oxygen away from the fire, thus stopping the chemical reaction.
