The chemistry of substances that contain carbon-hydrogen bonds.
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- Harmful Chemicals Found In Food
It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to...
- What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support
Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...
Attraction toward a magnetic field, stronger than diamagnetism, but still weak compared to ferromagnetism.
Substances that flow freely, gases and liquids.
Discovered : by Sir William Ramsay in London, and independently by P.T. Cleve and N.A. Langlet in Uppsala, Sweden in 1895.
Origin : The name is derived from the Greek ‘helios’,sun.
Description :A colourless, odourless gas that is totally unreactive. It is extracted from natural gas wells, some of which contain gas that is 7% helium. It is used in deep sea diving for balloons and, as liquid helium, for low temperature research. The Earth’s atmosphere contains 5 parts per million by volume, totalling 400 million tons, but it is not worth extracting it from this source at present.
Atomic No:2 MAss No:4
Cathode Ray Tube
Closed glass tube containing a gas under low pressure, with electrodes near the ends and a luminescent screen at the end near the positive electrode, produces cathode rays when high voltage is applied.
A type of geometrical isomerism related to the angles between like ligands.
Nickel-cadmium cell (Nicad battery)
A dry cell in which the anode is Cd, the cathode is NiO2, and the electrolyte is basic.
An oxidizing or reducing agent, who's mass gains (oxidizing agents) or loses (reducing agents) 6.022 x 1023 electrons in a redox reaction.
The mass of an acid or base that furnishes or reacts with 6.022 x 1023 H3O+ or OH- ions.
Spectrum that contains all wave-lengths in a specified region of the electromagnetic spectrum.
A device used for accelerating charged particles along a straight line path.
Mixing a set of atomic orbitals to form a new set of atomic orbitals with the same total electron capacity and with properties and energies intermediate between those of the original unhybridized orbitals.
Describes processes that release heat energy.
Substance that stoichiometrically limits the amount of product(s) that can be formed.
The sum of the numbers of protons and neutrons in an atom, an integer.
Equation relating the rate of a reaction to the concentrations of the reactants and the specific rate of the constant.
Second Law of Thermodynamics
The universe tends toward a state of greater diorder in spontaneous processes.
A method of counting electrons in a covalently bonded molecule or ion, counts bonding electrons as though they were equally shared between the two atoms.
Involves a change in the composition of a nucleus and can evolve or absorb an extraordinarily large amount of energy.
The separation of a liquid mixture into its components on the basis of differences in boiling points. The process in which components of a mixture are separated by boiling away the more volitile liquid.
A neutron ejected at high kinetic energy in a nuclear reaction.
A process pertaining to a change in structure of a protein form regular to irregular arrangement of the polypeptide chains.
