Question

Which of the following is an example of rapid combustion?

(a) phosphorous in water
(b) burning of a matchstick
(c) reaction of methane and oxygen in the air
(d) reaction of methane and oxygen in insufficient air

Answer 1

The burning of a matchstick is an example of rapid combustion, where a fuel reacts with oxygen in the air, releasing energy.

Step-by-step explanation:

The burning of a matchstick is an example of rapid combustion. When a matchstick is ignited, it undergoes rapid combustion, releasing heat and light. This is because the matchstick contains a fuel (such as phosphorous) that reacts with oxygen in the air, resulting in a rapid chemical reaction and the release of energy.
