solution of rational equation reducible to quadratic equation

Recall, a quadratic equation is of the form . An equation is said to be reducible to quadratic (or of quadratic form) if the variable factor of the leading term is the square of the variable factor in the second variable term. We can..

In the presence of other oxidizing agents, hydrogen peroxide acts as a reducing agent. This is because it can take up an atom of oxygen to give water and oxygen gas. It reduces silver oxide to silver. It decolourises pink colour of acidified solution of potassium ..

The partially concentrated hydrogen peroxide solution obtained above is further concentrated by distillation under reduced pressure (15 torr at 35C). However, a more concentrated solution can be prepared, if necessary, by repeated distillation over concentrated sulphu..

Identify a quadratic equation with solutions 2 and - 4. => x 2 - 2 x + 8 = 0 or x 2 + 2 x + 8 = 0 or x 2 - 2 x - 8 = 0 or x 2 + 2 x - 8 = 0..

Removing the reducible cuprous oxides of copper by the method of poling purifies blistered copper. The metal ore is initially melted in a shallow reverberatory furnace and the molten copper is stirred with logs of green wood. The blistered copper with cuprous oxide gets reduced..

Nitrobenzene is reduced to aniline as follows: 123 g 6F (6 x 96,5000) So, if the current efficiency is 100%, then 6 x 96500 C of electricity would be required to reduce 123 g of nitrobenzene. Then, Quantity of electricity (at 50% efficiency) required to reduce 1..

a) The equilibrium constant for this reaction is written in terms of the partial pressures of the reactants and products. So, b) This reaction is exothermic. So, its equilibrium constant should increase with the lowering of temperature. Therefore, the value of K p at 300 K will be greater than ..

Lithium aluminium hydride is one of the most popular complex hydrides. It is used as a very good reducing agent because it contains hydrogen in the form of hydride ion (H - ) and is extensively used in organic and inorganic reactions. For example, Inorganic reaction: On industrial sc..

(called hydration energy) is released in the third step. This compensates the higher energy needed to remove electron in second step. The net effect is that it has greater tendency to lose electrons in solution than other alkali metals and the reaction: Therefore, lithium is the strongest..

Formation of quadratic equations from given roots and conditions - Formation of quadratic equations from given roots and conditions. i) The quadratic equations whose roots are a and b is where S = sum of roots and P = product of roots ii) ..
