Striking A Match. When a match is lit, potassium, chlorine, phosphorus, and sulfur react and cause a combustion, which produces light and heat. This chemical reaction is exergonic because it releases energy and exothermic because it releases heat.Click to see full answer. People also ask, what happens when you light a match?Today’s matches create fire as the result of a simple chemical reaction. When a match is struck, friction creates heat and a flammable compound that ignites in the air. In modern matches, the two flammable compounds most often used are sulfur and red phosphorus.Furthermore, is lighting a match an exothermic reaction? Exothermic Reactions: Lighting a Match. An exothermic reaction is when less energy is used to break bonds in the reactants than is released when new bonds form in the products. The flame continues to burn until the heat energy reaches equilibrium. Thereof, what do you strike a match on? When you strike a match the red phosphorus is converted to white phosphorus for a fraction of a second, just enough to cause a spark of heat by reacting with oxygen in the surrounding air. This heat then ignites the first chemical on our journey – potassium chlorate.What chemical is used in match heads?Phosphorous sulfide is the chemical compound that ignites match heads. It’s found in the heads of strike-anywhere matches and in the strip on the side of safety match boxes. Other ingredients of match heads include potassium chlorate, phosphorous sesquisulfide, sulfur, glass powder, binders and fillers.
