product support process

The given organic compound is mixed with dry copper oxide (CuO) and heated in a hard glass tube. The products of the reaction are passed over (white) anhydrous copper sulphate and then bubbled through lime water. If copper sulphate turns blue due to the formation of CuSO 4 .5H 2 O (by wa..

. This is in the form of an alloy of iron called spiegeleisen. It contains carbon and manganese besides iron. The resulting product is manganese steel, which is removed by tilting the converter. Note: > Adding a little aluminium or silicon-iron alloy to molten steel helps in removing d..

Darwin found that all organisms have a natural capacity to produce more number of offspring than that survive. He quoted several examples to support this idea, the most classical being that of the elephant. Elephants are the slowest breeders in the animal kingdom. In a life span of about..

Acetone can also be prepared from propene by Wacker Process. In this process a gaseous mixture of propene and air is passed through a solution of copper (II) chloride and palladium (II) chloride between 293k to 333k. Acetone is also formed as by-product during the m..

In this process, molten sodium chloride (common salt) is electrolyzed using a graphite anode and a ring shaped iron cathode. The two electrodes are separated by a wire gauge partition to avoid the mixing of sodium and chlorine so formed. As Sodium chloride melts at a very high temperatur..

Sulphuric acid is prepared by contact process all over the world. Preparation of sulphuric acid by contact process is based upon the catalytic oxidation of SO 2 to SO 3 . There are five steps in the manufacture of sulphuric acid by the contact process: Productionh..

Product composition control and temperature control is possible. Scrap iron and iron ore can be directly converted to steel. No iron is lost as slag, since air is not directly passed through the molten metal. The regenerative system of heat economy ensures fuel saving. The s..

Introduction - When a chemical reaction gets started the reactants are present in the initial stage, but as the reaction proceeds, the concentration of the reactants decreases and that of products increases. Finally, a stage is reached when no further change in concentration of reactants ..

Sodium metal obtained has high degree of purity (99.5%). The starting material, sodium chloride is very cheap. Chlorine is obtained as a useful by-product..

1) Animals release water into the atmosphere by respiration in the form of vapours or to soil as fluid excretion. 2) Water returns to the environment after the death and decay of organisms (plants and animals). 3) A large part of water is given back to nature by plants, as they lose most of the ab..
