Hydrogen combines with non-metals like carbon, silicon, etc. to from covalent compound like halogens. Examples: CH 4 and CCl 4 . Remember : In 1766, Henry Cavendish, an English chemist, discovered hydrogen, by treating iron with dilute sulphuric acid. He also proved that when hydrogen is bur..

The carbon atoms of the parent chain are numbered as 1, 2, 3..., so as to assign the lowest number to the carbon atom where the multiple bond (double or triple) begins. The position of the multiple bond is indicated by adding the serial number of the first carbon of the multiple bond bef..

A hydrogen electrode in which pressure of hydrogen gas is maintained at 1 atm, and the concentration of H + ions in the solution is 1M is called a standard hydrogen electrode (SHE). As the potential of a standard hydrogen electrode is taken as 0.00 V at all temperatures. This electrode is used as..

There are mainly four steps in the mathematical formulation of linear programming problem as a mathematical model. We will discuss formulation of those problems which involve only two variables. 1. Identify the decision variables and assign symbols x and y to them. These decis..

It is that characteristic of a musical sound by which a shrill sound can be distinguished from a grave one, even though the two sounds may be of the same intensity. It is also defined as that characteristic of sound by which the ear assigns it a place on a musical scale. When a stretched..

The relationship between distance of the object (u), distance of the image (v) and focal length (f) of the lens is called lens formula or lens equation. -------- Lens formula This lens formula is applicable to both convex and concave lenses. Note: Points to be remembered while using ..

IUPAC Nomenclature for Elements with Z > 100 - All elements beyond uranium (Z=92) are synthesized in the laboratories and are known as 'trans uranium elements'. The elements, beyond fermium (Z=100) are known as 'trans fermium elements'. These elements have atomic numbers 101 onwards. Elements like ..

Constellations - Constellation is a group of stars visible within a particular region of the night sky. The stars that appear in the form of closed groups and form recognizable shapes and patterns are known as constellations. There are about 88 different constellations across the whole sky. But no ..
