Answer 1

Answer:

1)Antimony trisulphide on the matchstick head is the reason to burn when it is rubbing it on the side of the matchbox.

2) If your clothing catches fire: STOP where you are—moving or running feeds air to the flames and worsens the fire. DROP to the floor—if you stand up, the fire can burn your face. Fold your arms high on your chest to protect your face

Explanation :

1)The rubbing side of the matchbox has little red phosphorus with powdered glass and the head of the stick is made by the composition of potassium chlorate and antimony trisulphide.

When the matchbox surface is rubbed with the matchstick, red phosphorus in the rubbing surface converted into white phosphorus and that quickly reacts with potassium chlorate in the matchstick head creates enough heat to spark the antimony trisulphide and begins to fire the match stick .
