Question

White phosphorous burns in air on keeping .Name the type of combustion​

Answer 1

Explanation:

White phosphorus is highly reactive, and spontaneously ignites at about 30°C in moist air. It is usually stored under water, to prevent exposure to the air. It is also extremely toxic, even in very small quantities

Answer 2

Explanation:

Types of combustionCombustion is mainly of three types

(1) Rapid combustion (2) Spontaneous combustion (3) Explosion

1. Rapid combustion: The combustion in which the gas burns rapidly and produces heat and light is called rapid combustion.

For example: When a burning matchstick is brought near a gas burner and the gas tap is opened, the gas immediately starts burning with the production of heat and light. Eg. Petrol, LPG, spirit, etc.,

2. Spontaneous combustion: The combustion in which no external heat is given is known as spontaneous combustion.

For example: Burning of white phosphorus in air.

3. Explosion: The combustion in which large amount of gases are evolved with the production of a tremendous amount of neat; light and sound is called explosion,

For example: When a cracker is ignited, a sudden reaction, oxidation process takes place, and in which at high speed large amount of gas is evolved with the production of tremendous amount of heat, light and sound.
