some exceptional cases

Some Exceptional Cases - We may come across LPP which may have no feasible (infeasible) solution or may have unbounded solution. We conclude the chapter by giving one example for each of these exceptional cases..

We may come across LPP which may have no feasible (infeasible) solution or may have unbounded solution. If the intersection of the constraints is empty and the problem has no feasible solution. Therefore the given L.P.P has no solutio..

> In exceptional cases, where oxygen is not needed at all for burning there is a subtle difference between the terms combustion and burning. Combustion requires oxygen gas either from the air or that which is released from chemicals used in a reaction. When a chemical reaction t..

When food is oxidised without using molecular oxygen it is called anaerobic respiration. Anaerobic respiration is exceptional in some cases as in the tape worms living inside the human intestine. But temporary anaerobic respiration may occur even in our body in the fast working ..

While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic number has high atomic mass as well. If you recall from earlier lessons, Atomic number..

In mathematical sense, equilibrium constant is not a constant. It is called constant because at a fixed temperature and pressure, the value of the equilibrium constant for a reaction is constant. The unit of equilibrium constant (K) of a reaction depends upon the number of moles of the reactants a..

Two German biologists M.J.Schleiden (1838) and Theodore Schwann (1839) proposed the cell theory (or cell doctrine), which unified the ideas prevailing at that period on the organisation in plants and animals. The cell theory states that All living organisms are composed of minute structures called ..

In the presence of ultra-violet light halogens (Cl 2 , Br 2 , I 2 ) react with alkanes to form haloalkanes. In this method, polysubstituted halides are obtained that are difficult to separate. When pure components are needed, they can be obtained by fractional distillation. (Chloroform) ..

As in the case of S, the important oxidation states observed for Se and Te are also 2, +2, +4 and +6. The chalcogenide dianions (E 2 - ) exist only in their compounds with the most electropositive elements. By and large, chalcogens with the exception of polonium, display non-met..
