This post is a collection of Chemistry questions which are asked in RRB NTPC, SSC CGL, SSC CHSL, UPSC and many other Government examinations.

  • The gas which is present in both the natural gas and the bio-gas is : Methane
  • The Ozone layer is found in the earth’s atmosphere mostly between: 20 to 50 km
  • Acid rain is caused due to the emission of the gases into the atmosphere are : Oxides of nitrogen and sulphur
  • The process of improving the quality of rubber by heating it with sulphur is called: Vulcanization

  • Anti-freeze for the automobile engines : Ethylene glycol
  • The water pollution in river is measured by the dissolved amount of : Oxygen
  • Fruits stored in a cold chamber exhibit longer storage life because : rate of respiration is decreased
  • Nutrient Deficiency disease
