A match is a tool for starting a fire.Typically, matches are made of small wooden sticks or stiff paper.One end is coated with a material that can be ignited by frictional heat generated by striking the match against a suitable surface. However, the friction matches we’re used to have their origins in the 1800s; the first were developed by the English chemist, John Walker, in 1826. There are two different types of matches manufactured. Matchstick manufacturing is all about dealing with hazardous and explosive items. In 1845, Anton Schrötter von Kristelli discovered that heating white phosphorus, or exposing it to sunlight, turned it into another form of the element: red phosphorus. The wood is commonly composed of white pine or Aspen due to rigidness and workability. 3. No formula can be written for a mixture. Properties of hydrochloric acid > It turns blue litmus solution red. When a chemical loses electrons we say it has been oxidized.
