Summary Simultaneous Equations - Finding the solution by the method of substitution. Finding the solution by the method of substitution. (i) Coefficients of one of the variables (say x) in the two equations are made equal, by multiplying them with suitable fa..

Solution is obtained by integrating both sides and substituting ..

. Sedimentation followed by Decantation is used to separate an insoluble solid from a liquid. Filtration is a more effective method of separating an insoluble solid from a liquid. A soluble solid can be obtained back from a liquid in which it dissolves by the process of evaporation. Disti..

Molecular Orbital Theory - Molecular orbital theory was proposed by F. Hund and R.S. Mulliken in 1932. The basic idea of molecular orbital theory is that atomic orbitals of individual atoms combine to form molecular orbitals. The electrons in molecules are present in the molecular orbitals, which a..

Single Electrode Potential - It is not possible to measure the absolute potential of a single electrode because neither the oxidation nor the reduction reaction can occur by itself. Also, we need two electrodes to measure the potential difference between two points. This difficulty can be solv..

The following are the steps to solve a system of linear equations using Cramer's rule. Step 1: Find the value of the determinant Step 2: If D 0, then the system has unique solution, given by Where D 1 , D 2 and D 3 are the determinants obtained from D by repl..
