(a) because is a very friendly compound having 4 electron in outer cell.

(b) The blackening of the vessels indicate sooty flame due to incomplete combustion of the fuel .

(c) Because detergents change the Ph value of water so it cause water pollution. detergents make water more basic in nature, the value of ph of water will move towards 9 to 10 from 7 so it affects the life in water.

Hey mate!

Here's your answer!

a) The element carbon forms a very large number of compounds. It's because, each 4 atoms of Carbon can form 4 different bonds. This is called catenation.
b) Air holes of a gas burner have to be adjusted when the heated vessels get blackened by the flame. It's because, Air holes is the place from where gas comes and and leads to burning of flame when these holes gets damaged then the passage of the gas gets blocked which in leads to inadequate burning leading to blackened vessel.
c) Use of synthetic detergents causes pollution of water. Its because, detergents change the pH value of water so it cause water pollution. detergents make water more basic in nature, the value of ph of water will move towards 9 to 10 from 7 so it affects the life in water.

Hope it helps :)
