gas price reduction

Set up the apparatus as shown in figure 6.10. Liquor ammonia is taken in the test tube and boiled. It decomposes to yield ammonia gas and water vapour. The ammonia combines with the chlorine, forming thick white fumes of ammonium chloride. (ii) Ammonia with excess chloride If the chl..

In certain cases CO gas produced in the furnace itself can be used as a reducing agent. For example,..

. Addition of Hydrogen Hydrogen adds to chlorine to form hydrogen chloride gas. Nowadays, one can explain oxidation- reduction in terms of 'electrons transfer', which one will learn later on. Also, it is necessary to point out that oxidation and reduction reactions occ..

Blast furnace is a cylindrical furnace made by refractory bricks surrounded by a steel shell. Blast Furnace Height of the furnace: 60-100ft Base of the furnace: 30-35 ft Double cup and cone arrangement It allows the entry of charge into furnace but does not allow any gas to escape through..

7. 1.375 g of cupric oxide on reduction in hydrogen gas gives 1.098 g of copper. In another experiment, 1.179 g of metallic copper produced 1.476 g of copper oxide. Show that these results illustrate the law of constant proportio..

The hydrogen gas, which is just liberated as a result of a chemical is called nascent hydrogen or newly born hydrogen. It is obtained by passing dihydrogen gas at atmospheric pressure through an electric arc between two tungsten rods. The electric arc maintains a temperature ar..
