which gas is released when a matchstick burns
Answers
Answer:
HEY MATE HERE IS YOUR ANSWER ☺
Explanation:
THE TYPE OF GAS WHICH IS EMITED WHEN A MATCHSTICK IS LIT DEPENDS ON THE MATERIAL USED IN ITS HEAD . THE USUALLY USED MATCHSTICK HEAD ARE AN ADMIXTURE OF RED SULPHER IN MAJOR PORTION AND RED PHODPHOROUS IN TRACE QUANTITIES . THE GAS THAT IS EMITTED WHEN A MATCHSTICK LIT OR BURNS IS THEREFORE SULPHER DIOXIDE.

Explanation:
The type of gas that is emitted when a matchstick is lit depends on the material used in the matchstick heads. The usually used match stick heads are an admixture of red sulphur in major portion and red phosphorous in trace quantities.When the matchstick is struck on the box, the friction caused is sufficient to ignite the phosphorus. The combustion of phosphorus is exothermic and hence releases heat. The sulphur in the head in turn catches fire by reacting with atmospheric oxygen to give sulphur dioxide. The gas that is emitted, when an ordinary matchstick is lit, is, therefore, sulphur dioxide. The cellulose of the matchstick that is subsequently burnt emits CO{-2}gas. . In matchsticks, such as those used in Diwali fireworks, a variety of chemicals, in minimal quantities, are used for a variety of colours and a sparkling effect.Matchsticks heads are basically made up of three items (there are more obviously, but they do the side businesses).
It consists of -
Igniter - red phosphorus
Fuel - sulphur
Oxidiser - potassium chlorate
First the red phosphorus initiate the burning and reacts with potassium chlorate to form phosphorus pentoxide and potassium chloride.
Note that phosphorus pentoxide is in the form of WHITE FUMES. So this the gas which is evolved in the beginning. Later sulphur burns to form sulphur dioxide which is the gas evolved later .A matchstick does not catch fire and burn on its own at room temperature because the ignition temperature of matchstick is higher than the room temperature.A matchstick starts burning on rubbing it on the side of the matchbox because the heat produced by friction heats the chemical at the head of the matchstick to their ignition temperature and makes it catch fire. Kerosene oil and wood do not catch fire on their own at room temperature because the ignition temperature of kerosene oil and wood are higher than the room temperature.If kerosene is heated little it will catch fire easily because kerosene oil has a comparatively low ignition temperature which is reached even on little heating. If wood is heated a little,it does not catch fire because wood has a higher ignition temperature which is not reached by little heat being supplied to it by a matchstick.We see cooking oil in a frying pan catching fire when the frying pan is kept over a burning stove for a long time because the cooking oil gets heated to its ignition temperature when kept over a burning stove for a long time. A matchstick can light a tiny splinter of wood but not a big log of wood.A splinter of wood has a low ignition temperature.A burning matchstick can produce sufficient heat to reach the ignition temperature of the splinter of wood therefore a matchstick can light a splinter of wood directly. The ignition temperature of log of wood is high and cannot be reached by the small heat produced by a burning matchstick.So,a matchstick cannot light a log of wood directly.In order to burn a log of wood,a small fire is first started by burning straw with a matchstick,and then the log of wood is placed over this fire.Heat of this fire then heats the log of wood to its ignition temperature due to which the log of wood starts burning. Coal has a high ignition temperature,so a coal fire cannot be started by using a lighted matchstick directly.This is because the small heat produced by burning matchstick is not sufficient to heat the coal to its ignition temperature.A piece of cloth is dipped in kerosene oil and some pieces of cloth is ignited by a lighted matchstick,it starts burning.The heat produced by the burning of kerosene soaked cloth makes the pieces of wood to burn.the coal pieces are then placed over the burning wood pieces.The large heat produced by the burning wood pieces heats the coal to its ignition temperature due to which the coal also starts burning.
