Compounds containing predominantly covalent bonds.
- 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?
- 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...
- 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'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...
Law of Combining Volumes (Gay-Lussac's Law)
At constant temperature and pressure, the volumes of reacting gases (and any gaseous products) can be expressed as ratios of small whole numbers.
The chemistry of substances that contain carbon-hydrogen bonds.
Amount of solute per unit volume or mass of solvent or of solution.
A salt containing an ionizable OH group.
Of the same energy.
A device for accelerating charged particles along a spiral path.
Arbitrary numbers that can be used as mechanical aids in writing formulas and balancing equations, for single- atom ions they correspond to the charge on the ion, more electronegative atoms are assigned negative oxidation numbers (also called Oxidation states).
A number that indicates how smoothly a gasoline burns.
Regular periodic variations of properties of elements with atomic number (and position in the periodic table).
Energy required to pair two electrons in the same orbital.
Compounds that contain only carbon and hydrogen.
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.
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.
Forcing solvent molecules to flow through a semipermable membrane from a concentated solution into a dilute solution by the application of greater hydrostatic pressure on concentrated side than the osmotic pressure opposing it.
Equilibria involving species in more than one phase.
At constant pressure the volume occupied by a definite mass of gas is directly proportional to its absolute temperature.
The attractive forces that hold atoms together in elements or compounds.
A negative ion, an atom or goup of atoms that has gained one or more electrons.
Alpha (a) Particle
Helium ion with 2+ charge, an assembly of two protons and two neutrons.
