What medicine is on the matchstick and what material is used to wipe the skin on both sides of the matchbox?

The components in safety matches are: the matchhead is mainly composed of oxidant (KClO3), combustible substances (such as sulfur) and adhesive. The side of the matchbox is mainly composed of red phosphorus, antimony trisulfide and adhesive. When striking a match, the matchhead rubs against the side of the matchbox to generate heat, and the released heat decomposes KClO3, producing a small amount of oxygen, which ignites red phosphorus, thus burning combustible substances (such as sulfur) on the matchhead and igniting the match.

The advantage of safety matches is that it is not only safer to separate red phosphorus from oxidant, but also the chemicals used are non-toxic. So it's also called a safety race.

★★★★ The material of the safety match head and the side of the matchbox is as right.

As shown in the figure, when the two are rubbed, the red phosphorus is heated and ignited, causing the match stick to catch fire.

Fill in the blanks as required:

① The chemical equation of potassium chlorate decomposition is 2KClO3 2KCl+3O2↑.

② The chemical equation of red phosphorus reaction is 4p+5o2 2p2o5, and the reaction type is combination reaction.
