Answer 2

(b) Phosphorus is the main chemical component present in the striking surface of a matchbox

Explanation:

• The head of the matchstick is covered with potassium chlorate. Due to the friction, heat is generated between the surface of the matchbox and the matchstick when we strike.
• This heat breaks a small part of the red phosphorus chain. Which transforms red phosphorus into white phosphorus. White phosphorus is a highly volatile chemical that eventually ignites in the air.
