Decomposition by heating a substance in the presence of a catalyst and in the absence of air.
- 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 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...
- 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...
- 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?
- 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...
Amount of a specified pure product actually obtained from a given reaction. Compare with Theoretical Yield.
The relative order of tendencies for elements and their simple ions to act as oxidizing or reducing agents, also called the activity series.
A molecular orbital derived only from an atomic orbital of one atom, lends neither stability nor instability to a molecule or ion when populated with electrons.
A unit of energy in the SI system. One joule is 1 kg. m2/s2 which is also 0.2390 calorie.
A quantity that characterizes the position of equilibrium for a reversible reaction, its magnitude is equal to the mass action expression at equilibrium. K varies with temperature.
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.
A solid compound that contains a definite percentage of bound water.
A very slightly soluble compound.
A substance whose aqueous solutions do not conduct electricity.
High energy particles or rays emitted during the nuclear decay processes.
The arrangement of atoms (not lone pairs of electrons) around a central atom of a molecule or polyatomic ion.
Compartment in which the oxidation or reduction half-reaction occurs in a voltaic cell.
The geometric arrangement of orbitals containing the shared and unshared electron pairs surrounding the central atom of a molecule or polyatomic ion.
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.
An oily, slightly water-soluble liquid, C7H6O2, having an almondlike odor: used chiefly in perfumery and in the synthesis of coumarin.
A measure of the intensity of heat, i.e. the hotness or coldness of a sample. or object.
Valence Shell Electron Pair Repulsion Theory
Assumes that electron pairs are arranged around the central element of a molecule or polyatomic ion so that there is maximum separation (and minimum repulsion) among regions of high electron density.
The arrangement of atoms (not lone pairs of electrons) about the central atom of a polyatomic ion.
Study of chemical changes produced by electrical current and the production of electricity by chemical reactions.
Primary Voltaic Cells
Voltaic cells that cannot be recharged, no further chemical reaction is possible once the reactants are consumed.
