Question

write the balanced equations to show the formation of H2SO4 and HNO3 in the acid rain?​

Answer 1

Answer:

Sulphur dioxide + water → sulphurous acid + hydrogen

SO

2

+3H

2

O→H

2

SO

3

+2H

2

Sulphur trioxide + water → sulphuric acid

SO

3

+H

2

O→H

2

SO

4

Nitrogen dioxide + water → Nitric acid + hydrogen

2NO

2

+2H

2

O→2HNO

3

+H

2

As the carbonic acid, formed by CO

2

, is a very weak acid, and the composition of CO

2

in the air is only approximately 0.03%, its effect on our environment is negligible. It is only the man-made compounds of SO

2

, and NO

2

are the main culprits for acid rain.

Answer 2

Answer:

Sulphur dioxide + water → sulphurous acid + hydrogen

SO2 + 3H2O --------> H2SO3 + 2H2(below)

Sulphur trioxide + water → sulphuric acid

SO3+H2O----------> H2SO4

Nitrogen dioxide + water → Nitric acid + hydrogen

2NO2+ 2H2O ------->2HNO3+H2( below)

As the carbonic acid, formed by CO2

in the air is only approximately 0.03%, its effect on our environment is negligible. It is only the man-made compounds of SO2
