Question 1

what are contaminants that result in acid rain

Answer 1

so2, Sulphur dioxide
nox, nitrogen dioxide and monoxide

Question 2

what is acid rain and nox

Answer 2

3NO(g)+H2O(l)——2HNO3(aq)+NO(g)

NO(g)+1/2O2(g)——-NO2(g)

Question 3

what is acid rain and SO2

Answer 3

SO2(g)+1/2O2(g)—SO3(g)

SO3(g)+H2O(l)–H2SO4(aq)

Question 4

what are the consequences of acid rain

Answer 4

1. Damage to plants
2. damage to water resources
3. chemical imbalance in the soil
4. Erosion of city infrastructures

Question 5

what is the ozone layer

Answer 5

• it is a part of the atmosphere with a high concentration of O3.
• Absorbs some of the uv rays from the sun

Question 6

Answer 8

it is above antarctica and its showing signs of recovery.

Question 9

what is smog

Answer 9

smoke+fog=smog

Question 10

what is photochemical smog

Answer 10

chemical reactions taking place in the presence of sunlight- nitrogen oxides, sulphur dioxide, tropospheric ozone.

Question 11

Formation of tropospheric ozone

Answer 11

• when sunlight comes into contact with nitrogen oxides and volatile organic compounds they bake together and create ozone.

Question 12

formation of smog

Answer 12

NO2(g)+SO2(g)+O3(g)=SMOG
