- 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...
Chemical Hygiene Plan (CHP)
A written program developed and implemented by an employer designating proceedures, equipment, personal protective equipment, and work practices that are capable of protecting employees from the health hazards presented by hazardous chemicals usid in that particular workplace.
A heavy, colorless, chemically inactive, monatomic gaseous element used for filling radio, television, and luminescent tubes. Symbol: Xe, at. wt.: 131.30, at. no.: 54.
Heat of Fusion
The amount of heat required to melt one gram of solid at its melting point with no change in temperature. Usually expressed in J/g. The molar heat of fusion is the amount of heat required to melt one mole of a solid at its melting point with no change in temperature and is usually expressed in kJ/mol.
A theory, that attempts to explain macroscopic observations on gases in microscopic observations on gases in microscopic observations on gases in microscopic or molecular terms.
Nuclide that undergoes nuclear decay.
The combination of many small molecules to form large molecules.
The point at which an indicator changes colour and a titration is stopped.
Free Energy Change
The indicator of spontaneity of a process at constnt T and P. If delta-G is negative, the process is spontaneous.
Reaction of a substance with water.
Elements 89 to 103 (between lawrencium and actinium) on the periodic table. Only the first four have been found in nature in appreciable amounts. The remainder have been produced synthetically.
Region or volume in space in which the probability of finding electrons is highest.
Process of reducing the concentration of a solute in solution, usually simply by mixing with more solvent.
A colorless, crystalline compound, XeF6, that melts at 50°C to a yellow liquid, and boils at 75°C.
Group of atoms remaining after a hydrogen atom is removed from the aromatic system.
The variations in properties of elements with their position in the periodic table.
Compound in which an alkyl or aryl group and a hydrogen atom are attached to a carbonyl group and a hydrogen atom are attached to a carbonyl group, general formula, O-R-C-H
Law of Partial Pressures (Dalton's Law)
The total pressure exerted by a mixture of gases is the sum of the partial pressures of the individual gases.
A process for the catalyzed industrial production of ammonia from N2 and H2 at high temperature and pressure.
Compound containing both an amino and a carboxylic acid group.The --NH2 group.
Resistance offered by the molecules of a liquid to flow is termed as viscosity.
