How can photochemical smog be controlled?

By using catalytic converters in the automobiles/industry

The normal rain water is slightly acidic and its pH value is 5 . 6 because of which one of the following ?

2 SO 2 + O 2 + 2 H 2 O → 2 H 2 SO 4

4 NO 2 + O 2 + 2 H 2 O → 4 HNO 3

Given below are two statements : Statement I : H 2 O 2 is used in the synthesis of Cephalosporin Statement II : H 2 O 2 is used for the restoration of aerobic conditions to sewage wastes. In the light of the above statements, choose the most appropriate answer from the options given below :

Both Statement I and Statement II are correct

Statement I is correct but Statement II is incorrect

Statement I is incorrect but Statement II is correct

Both Statement I and Statement II are incorrect

Identify X , Y and Z in the following reaction. (Equation not balanced) Cl O ∙ + NO 2 → X ¯ ⟶ H 2 O Y ¯ + Z ¯

X = ClONO 2 , Y = HOCl , Z = HNO 3

X = ClONO 2 , Y = HOCl , Z = NO 2

X = ClNO 2 , Y = HCl , Z = HNO 3

X = ClNO 3 , Y = Cl 2 , Z = NO 2

The water quality of a pond was analysed and its BOD was found to be 4 . The pond has

Water has high amount of fluoride compounds

Some reactions of NO 2 relevant to photochemical smog formation are Identify A , B , X and Y

X = [ O ] , Y = NO , A = O 2 , B = O 3

X = N 2 O , Y = [ O ] , A = O 3 , B = NO

X = 1 2 O 2 , Y = NO 2 , A = O 3 , B = O 2

X = NO , Y = [ O ] , A = O 2 , B = N 2 O 3
