determinant method

Victor Meyer's method is used for the determination of molecular masses of volatile substance..

We have seen the application of matrices and determinants in solving system of linear equation with three unknown variables. Matrices and determinants are also widely used in solving large system of linear equation. Some of these methods are Gauss-elimination meth..

Determination of the relative proportions (as percentages) of various elements present in an organic compound is called quantitative analysis of the compound. The percentages of the various elements present in the compound are estimated by suitable chemical methods as describ..

Organic compounds are isolated either from natural sources or from reaction mixtures. These compounds are seldom pure and are usually contaminated with small amounts of other similar compounds, which are found to exist together or formed during the reaction. In order to characterize them, it is imp..

(i) The law of octaves was the first logical attempt to classify elements on the basis of atomic weights. (ii) Periodicity of elements was recognised for the first time. Remember:- In 1860, there was a conference of chemists in Karl Sruhe, Germany. During this conference, Stanislao Cannizaro,..

The mass percentage of each constituent element present in any compound is called its percentage composition. This may be obtained from the molecular formula of the compound by using the relationship:..

Types of linear systems Gauss-Jordan elimination, Gauss-Jordan method Vectors and vector addition Geometrical solution sets of systems of equations Rectangular matrices to row echelon form Matrix multiplication Inverse to a square matrix Determinants of 2 by 2 and 3 by 3 mat..

The law of octaves was the first logical attempt to classify elements on the basis of atomic weights. Periodicity of elements was recognized for the first time. Remember In 1860, there was a conference of chemists in Karl Sruhe, Germany. A young Russian chemist, Dmitri Mendeleev, atten..

By trial and error method, find the factor of the constant for which the given expression becomes equal to zero. Divide the expression by the factor that is determined in step 1. Factorise the quotient. If the quotient is a trinomial, factorise it further. If the expr..

Processes for Purification - The identification and characterization of an organic compound such as molecular formula etc., must have the compound available in pure form. The process of obtaining the compound in its purest form from an impure sample or from any reaction mixture is called purificati..
