Potential difference, Ecell, between oxidation and reduction half-cells under nonstandard conditions.
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- Diamonds Are Forever
Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?
- Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...
- Chemical Safety
People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...
- What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...
Substances consisting largely of hydrocarbons, derived from decay of organic materials under geological conditions of high pressure and temperature (metamorphism) include coal, petroleum, natural gas, peat and oil shale. For further information see Fuel Chemistry
Heat of Crystallization
The amount of heat that must be removed from one gram of a liquid at its freezing point to freeze it with no change in temperature.
Net Ionic Equation
Equation that results from canceling spectator ions and eliminating brackets from a total ionic equation.
The solvent-like phase in a colloid.
A physical state of matter which exists at extremely high temperatures in which all molecules are dissociated and most atoms are ionized.
A change in which one or more new substances are formed.
Potentials, E, of half-reactions as reductions versus the standard hydrogen electrode.
Discovered : by Henry Cavendish in 1766.
Isolated in London, UK.
Origin : The name is derived from the Greek ‘hydro genes’, meaning water forming.
Description :A colourless, odourless gas that burns and can form an explosive mixture with air. It is currently manufactured from methane gas, but is also produced by the electrolysis of water and aqueous salts. The gas is used to make such key materials as ammonia, cyclohexane and methanol, which are intermediates in the production of fertilisers, plastics and pharmaceuticals. Some see hydrogen gas as the clean fuel of the future - generated from water and returning to water when it is oxidised. Hydrogen-powered fuel cells are increasingly being seen as pollution-free sources of energy.
Combination of symbols that indicates the chemical composition of a substance.
A process for the industrial production of nitrogen oxide and nitric acid from ammonia and oxygen.
Isomers in which a particular ligand bonds to a metal ion through different donor atoms.
The drawing of a liquid up the inside of a small-bore tube when adhesive forces exceed cohesive forces, or the depression of the surface of the liquid when cohesive forces exceed the adhesive forces.
A substance that cannot be decomposed into simpler substances by chemical means.
Corrects standard electrode potentials for nonstandard conditions.
The mass of one formula unit of a substance in atomic mass units.
Ions in a solution that do not participate in a chemical reaction.
A plant extract that has a distinctive odour or flavour.
A solid characterized by a regular, ordered arrangement of particles.
Metal with low ionization energy that loses electrons readily to form cations.
The vapor pressure of a solvent in an ideal solution decreases as its mole fraction decreases.
