Which of the following is also known as laughing gas?

Which of the following is also known as laughing gas? Correct Answer Nitrous oxide

The correct option of Nitrous Oxide.

Key Points

  • Nitric acid has the chemical formula HNO3 and its other name is Acidum nitricum.
  • Nitric oxide is prepared industrially by passing air through an electric arc or by oxidation of ammonia over platinum gauze.
  • Nitrogen pentoxide is used in chloroform solution as a nitrating agent. Its chemical formula is N2O5.
  • Nitrogen pentoxide is produced by dehydration of nitric acid by phosphorus pentoxide.
  • Nitrous oxide is prepared by thermal decomposition of ammonium nitrate.

Additional Information

  • Nitrogen dioxide It has an irritating odor and is highly poisonous. Under normal atmospheric conditions, it exists in equilibrium with nitrogen tetroxide (N204). Heavier than air. Nitrogen dioxide produces nitrous acid (HN02) and nitric acid (HN03) on contact with water.
  • Nitrogen pentoxide Sublimes at -32.4°C but undergoes moderately rapid decomposition into 02 and the NO2/N204 equilibrium mixture at temperatures above -10°C. Freely soluble in chloroform without appreciable decomposition.
  • Nitrous oxide supports combustion. Very stable and rather inert chemically at room temperatures. Dissociation begins above 300°C when the gas becomes a strong oxidizing agent.
  • Nitric oxide Burns when heated with hydrogen. It combines with oxygen to form nitrogen dioxide and with halogens to form nitrosyl halides, e.g. NOCl.

In a newly developed innovative idea brought up by CSIR in India, gas turbine exhaust gas are being utilized to convert feedwater into steam. Certain data of the experiment are as follows: mass flow rate of exhaust gas = 40 kg/hr, enthalpy of exhaust gas at the time of their exit from gas turbine is 600 kJ/kg, steam turbine output as measured by brake dynamometer = 60 hp-sec, thermal efficiency of steam power plant is 0.25, efficiency of exhaust gas in converting feedwater into steam is taken as 50%. Find the enthalpy of exhaust gas remaining after they generate steam from feedwater?
