Many people who hated to ask for directions would just continue to drive until they finally found where they needed to go. Those days are now gone, thankfully, with the help of car......

Control systems are widelyused in industry because: Many processes used in industry are very complicated and can work very quickly They help maintain......

This page describes how a mass spectrum is produced using a mass spectrometer. How a mass spectrometer works The basic principle If something is moving and you subject it to a sideways force,......

( Nuffield Advanced Science Book of Data , and Chemistry Data Book by Stark and Wallace). There are also important inconsistencies within the books (one set......

This page describes how the physical properties of substances having molecular structures varies with the type of intermolecular attractions - hydrogen bonding or van der Waals forces.......

This page looks at the information you can get from the mass spectrum of an element. It shows how you can find out the masses and relative abundances of the various isotopes of the element and......

This page explains the various ways that organic molecules can be represented on paper or on screen - including molecular formulae, and various forms of structural formulae. Molecular formulae......

This page explains how to work out the shapes of molecules and ions containing only single bonds. If you are interested in the shapes of molecules and ions containing double bonds, you will find......

This page explains how to find the relative formula mass (relative molecular mass) of an organic compound from its mass spectrum. It also shows how high resolution mass spectra can be used to find......

This page explains how the M+1 peak in a mass spectrum can be used to estimate the number of carbon atoms in an organic compound. Note: This is a small corner of mass spectrometry. It would be a......

The Falling Asleep ProcessDuring the day when we are a awake, our body and brain are working tirelessly to operate our body, and as they do so they slowly degrade at a cellular level. A person......

This page explains how the M+2 peak in a mass spectrum arises from the presence of chlorine or bromine atoms in an organic compound. It also deals briefly with the origin of the M+4 peak in......

This page explains the origin of the two weaker forms of intermolecular attractions - van der Waals dispersion forces and dipole-dipole attractions. If you are also interested in hydrogen......
