The increasing amount of carbon dioxide in the air is slowly raising the temperature of the atmosphere, because it absorbs

(a) Reduce the consumption of petrol in the automobiles. (b) Use of CNG or clean fuel. (c) Instead of burning litter prepare manure out of it. (d) Treatment of smoke to remove harmful...

(C) carbon dioxide only

(i) Nitrogen

(b) Dust particles are responsible for the diffusion of light in atmosphere.

(d) Acid rain is caused by a chemical reaction that begins when compounds of sulphur dioxide and nitrogen oxide react with molecules in the atmosphere to produce acids.

(c) Since CO2 is heavier than air, it sinks in ocean than moving up. Also, during winter, it is observed that CO2 is trapped in ice caps.

(C) totally different from both carbon and oxygen

(b) rise in temperature 

(i) Substance X- Calcium Hydroxide. Ca(OH)2(aq) + CO2(g)  → CaCO3(s) H2O (ii) Calcium hydroxide is obtained by reaction of calcium oxide and water. CaO(s) + H2O(l) → Ca(OH)2(aq) + Heat 

(i) Substance X is lime water. Ca(OH)2 + CO2 → CaCO3 + H2O Ca(OH)2  -(Lime water) CO2   -(Carbon dioxide) CaCO3 -(Calcium carbonate) H2O - (Water) (ii) Calcium oxide reacts vigorously with water to produce slaked lime (calcium hydroxide) releasing a large amount of...
