Question

*Define:
1) Flame
2) Fuel efficiency
3) Fire Extinguisher​

Answer 1

Answer:

3)It consists of two cylinders:

foam type - fire

Outer cylinder: It is made of metal (contains baking soda).

Inner cylinder: It is made up of glass which contains aluminium sulphate and aluminium sulphate is mixed with saporin.

Both cylinders are bound by common knob. When the knob is pressed, the glass cylinder breaks. Then both chemicals, including baking soda and aluminium sulphates get mixed, react and as a result, produce carbon dioxide that comes out with great pressure, cuts off oxygen supply and fire gets extinguished.

NaHCO3 + Al2(SO4)3 (Aluminium sulphate) → Na2SO4 + Al2(CO3) + CO2 + H2O

Hence, we can say that carbon dioxide is a non supporter of combustion. Saporin which is mixed is useful in formation of Carbon Dioxide and it form Carbon Dioxide in the form of foam
