1.	Which gas is responsible for acid-rain ?
Answer» `CO_2` `NH_3` `CH_4` `NO_2` Solution :When the pH of rainy water is less than 5.6 , the rain is called acid rain. `H_2 SO_4 and H_2 NO_3` are produced by COMBINATION of `SO_2 and NO_2` in the moisture produced by combustion of PETROL and diesel of vehicles and combustion of fossil fuels like petroleum and coal.` 2SO_(2(g)) + O_(2(g)) + 2H_2 O_((l)) to 2H_2 SO_(4(aq))` `2H_2 O_((l)) + 4NO_(2(g)) + O_(2(g)) to 4HNO_(3(aq))` This acidic clouds STRETCHED with the flow of wind and it rains where the situation is PROPER.
