Question

Which chemical is used to make an auto fire or match a stick burner from some distance?

Answer 1

Hint: There are various chemicals involved in burning a match stick or to cause an auto fire. One chemical solely is not included as it takes more than one chemical to cause proper fire with safety and which will be independent of a source like gas.

Complete answer: Many chemical combinations can be used to cause auto fire. The particular chemicals that are used to make auto fire or make a fire with matchsticks are potassium chlorate, sulphur, starch and glue.
In case of the matchstick’s auto fire, the matchsticks come packed in an open table box. The sides of the box are red and they are used to ignite the fire. The matchstick is rubbed on it quickly and the matchstick will be ignited.
The side of the box is red due to the presence of red phosphorus in it. The side of the box also consists of binder and powdered glass, this helps the matchstick to get a good grip and friction on the side.
The friction between the matchstick and the side of the box is the reason that causes fire. The matchstick head contains oxygen and sulphur, as they are rubbed over the side of the box containing red phosphorus, the matchstick gets ignited and the wood at the end of the matchstick head keeps burning until it completely burns.
The oxygen and sulphur on the matchstick head burn slowly enough to give time for the matchstick wood to burn easily. Thus, to cause an auto fire we require potassium chlorate, sulphur, starch and glue.

Note:
The gas burner that is there in any household might be called an auto fire, it requires a constant supply of liquefied gas though. The fire that burns on a matchstick requires a constant supply of oxygen that it gets from the air. Thus a matchstick cannot be ignited in a place where there is low oxygen.
