What's the reason why vinega,water, baking soda in a paper hanky inside a jar be a fire extinguisher?

Question

This is a my son's science project. and i would just like to help him out..

Answer 1

When you turn the fire extinguisher vessel upside down, the action dumps the baking soda, NaHCO3, into the vinegar (5% acetic acid, HC2H3O2, in water) to generate cabon dioxide, CO2. The CO2 pressure in the vessel squirts the liquid through a hose onto the fire.

NaHCO3 + HC2H3O2 ===> NaC2H3O2 + CO2 + H2O

Answer 2

Because all of them combined traps the heat it has gotten somethng to do with their properties and it is also because that none of them are flammable so all forces joined together stops the fire from burning thereby extinguishing it.
