Ammonia molecule has a strong tendency to donate its lone pair of electrons of nitrogen to other molecules. Thus, it acts like a strong Lewis base. In aqueous solutions, NH 3 ionizes in accordance with the reaction...

Objective Function - The Objective Function is a linear function of variables which is to be optimised i.e., maximised or minimised. e.g., profit function, cost function etc. The objective function may be expressed as a linear expressio..

Set: A well-defined collection of distinct objects is called a set. Notation of Sets: Capital letters are usually used to denote or represent a set. Representation of Sets: There are two methods of representing a set. (i) Roster Method (ii) Set builder form. Finite an..

Basic oxides are the oxides of metals. If soluble in water they react with water to produce hydroxides (alkalies) e.g., ..

Limitations of Linear Programming - Linear programming is applicable only to problems where the constraints and objective function are linear i.e., where they can be expressed as equations which represent straight lines. In real life situations, when constraints or objective fun..

Linear Programming Problems (LPP) - The standard form of the linear programming problem is used to develop the procedure for solving a general programming problem. A general LPP is of the form Max (or min) Z = c 1 x 1 + c 2 x 2 + +c n x n x 1 , x 2 , ....x n are called..

Basic Characters of Amines - In amines, there is a lone pair of electrons on nitrogen. The tendency of nitrogen to share these electrons with acids is responsible for the basic character of amines. For comparison of the basic character of amines, the equilibrium c..

A basic buffer contains a weak base (BOH), and its salt with strong acid (BX). The buffer solution thus contains large amounts of the weak base BOH, and the cation B + (coming from the dissociation of the salt BX), in addition to H 3 O + and OH - . The addition of an acid or a base to ..
