invented aqua-ammonia absorption system in 1860. Water is a strong absorbent of NH3. If NH3 is kept in a vessel that is exposed to another vessel containing water‚ the strong absorption potential of water will cause evaporation of NH3 requiring no compressor to drive the vapours. A liquid pump is used to increase the pressure of strong solution. The strong solution is then heated in a generator and passed through a rectification column to separate the water from ammonia. The ammonia vapour is then

wartime‚ to do everything in their power to help the country. Fritz Haber‚ a German scientist who said to be a patriot during the World-War 1. He put all his effort to invent the way of creating Ammonia‚ that to help Germany his country to defeat the enemies. And also as the creation of making Ammonia‚ he won the Nobel Prize in chemistry in 1918. Haber was born on December 9‚ 1868 in Breslau Germany. After the completion of his University studies‚ he worked for a time in his father’s chemical

THE ORGANISM MAY EXCRETE UREA‚ URIC ACID OR AMMONIA. 5. Why would it be disadvantageous for humans to excrete nitrogenous waste in the form of ammonia? How are fish adapted for the excretion of ammonia? AMMONIA IS VERY TOXIC AND MUST BE IMMEDIATELY REMOVED FROM THE VACINITY OF CELLS. THIS CAN BE DONE BY IMMEDIATELY DIFFUSING IT INTO A LARGE QUANTITY OF WATER. HUMANS DO NOT HAVE ENOUGH WATER TO DILUTE THE TOXIN. FISH DIFFUSE THE AMMONIA IMMEDIATELY OUT OF THEIR GILLS.
