Aqueous nitric acid obtained by this method can be concentrated by distillation to 68.5% by mass. Further concentration to 98% acid can be achieved by dehydration with concentrated sulphuric acid. Anhydrous nitric acid can be ob..
Acid Mist
Vapours of any acid introduced into the atmosphere causes acid mist. 'Sulphuric acid mist' is produced when SO 3 present in the atmosphere, comes in contact with moisture. Sulfur trioxide (SO 3 ) is produced by complete combustion and forms sulfuric acid by..

Summary - Ammonia is produced by decay of plant and animal tissues. Nitrogenous organic matters like urea in the urine and excreta of animals get acted upon by bacteria releasing ammonia. Ammonia is manufactured by Haber's Process by the reaction of 1 volume of nitrogen gas and ..

Very fast and clear. Made sure I understood the concepts instead of giving the answers to the problem.
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
