Question # 1

Write the harmful effects of Chlorination of water?

Ans 1: Harmful effects of chlorination of water are due to its reaction with dissolved ammonia and organic matters present in water,The hypochlorous acid reacts with dissolved ammonia to form chloramines .
Chlorination of water containing organic material aslo forms some organic compound which are toxic.

Question # 2

How gases in the atmosphere absorb?

Ans 1: The gases in the atmosphere absorbs most of the cosmic rays and the major portion of the harmful electromagnetic radiation coming from the sun,The absorption of these harmful radiation protects the life on the earth.

Question # 3

What is smog?What are the content of photochemical smog?

Ans 1: The word smog is combination of smoke and fog,Photochemical smog consists of higher concentration of oxidants like ozone and is also termed as oxidizing smog,The main reactants of photochemical smog are nitric oxide NO and unburnt hydrocarbons,Nitric acid is oxidizing to nitrogen dioxide within minutes to hours depending upon the concentration of pollutants gas.

Question # 4

What is the effect of Acid rain on earth?

Ans 1: Acidification of the soil and rocks can leach metals like aluminium ,mercury ,lead and calcium and discharges them into water bodies.These heavy metals are accumulated in the fished and are health hazards for human and birds they eat these fishes,The elevated concentration of aluminium is harmful for fished as it clogs the gills this causing suffocation,Acidification of the soil can also each nutrient thus damaging leaves and plants and growth of forest.

Question # 5

What is Biosphere?

Ans 1: Biosphere is the region of earth capable of supporting life.It includes lower atmosphere ,the oceans,rivers,soils and solid sediments that activity interchange material with all types of living organism i,e human beings animals,and plants.

Question # 6

What are sulphate aerosols?

Ans 1: SO₂,SO₃because of their pungent odour are very irritated and uccocating through various reaction in the atmosphere they form sulphate aerosols,These aerosol cause sever respiratory troubles particularly among older people.

Question # 7

What is Acid Deposition?How does it affect the building material?

Ans 1: The rain contains acid is called acid rain now a days it termed as acid deposition,It produce serious environmental problems.Acid rain is produced due to the presence of CO₂and NO_xin atmosphere convert it into carbon dioxide,.ACid rain damage building material such as steel,pain,plastics ,cement masonry work.

Question # 8

How ozone layer in stratosphere is affected by chlorofluorocarbons?

Ans 1: Chlorofluorocarbons used as refrigerants in air conditioning and in aerosol spray are inert in the troposphere but slowly diffuse into stratosphere ,where they are subjected to ultraviolet radiation generating Ci free radicals which react with ozone and cause depletion.

Question # 9

Why "CO' Carbon monoxide is highly poisonous gas.

Ans 1: Carbon monoxide is highly poisonous gas and cause suffocation if inhaled.It blinds blood hemoglobin more strongly than oxygen than oxygen thus excluding oxygen from normal respiration.The Co poisoning can reserved by giving high pressure oxygen.

Question # 10

Why ozone layer has depleting?

Ans 1: The concentration of ozone in the stratosphere is behind depet through various chemical reaction but the it is seriously affected by chlorofluorocarbons.chlorofluorocarbons used as refrigerants in air conditioning and in aerosol spray are inert in the troposphere but slowly diffuse into stratosphere ,where they are subjected to ultraviolet radiation generating Ci free radicals which react with ozone and cause depletion.
