Compounds containing predominantly covalent bonds.
- 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...
- 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...
- 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...
Compound containing the O-C-N group.Compound that can be considered a derivative of ammonia in which one or more hydrogens are replaced by a alkyl or aryl groups.
Of electrons, refers to bonding electrons that are distributed among more than two atoms that are bonded together, occurs in species that exhibit resonance.
The formation of a set of molecular orbitals that extend over more than two atoms, important in species that valence bond theory describes in terms of resonance.
A device for observing the paths of speeding particiles as vapor molecules condense on them to form foglike tracks.
The absorption of heat by a system as the process occurs.
Plating a metal onto a (cathodic) surface by electrolysis.
Primary Voltaic Cells
Voltaic cells that cannot be recharged, no further chemical reaction is possible once the reactants are consumed.
The release of heat by a system as a process occurs.
A sustance that coats the particles of the dispersed phase and prevents coagulation of colloidal particles, an emulsifier.
Adhesion of a species onto the surfaces of particles.
In describing crystals, the number of nearest neighbours of an atom or ion. The number of donor atoms coordinated to a metal.
Aufbau ('building up') Principle
Describes the order in which electrons fill orbitals in atoms.
A device used to measure the heat transfer between system and surroundings at constant volume.
Half-cells in which the oxidized and reduced forms of a species are present at unit activity, 1.0M solutions of dissolved ions, 1.0atm partial pressure of gases, and pure solids and liquids.
Activity of a component of ideal mixture
A dimensionless quantity whose magnitude is: equal to molar concentration in an ideal solution, equal to partial pressure in an ideal gas mixture, and defined as 1 for pure solids or liquids.
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.
Process that occurs in electrolytic cells.
The absolute entropy of a substance in its standard state at 298 K.
The sum of the molalities of all solute particles in a solution.
The ratio of the density of a substance to the density of water.
In a cathode ray tube, the positive electrode. Electrode at which oxidation occurs.
