Reactions in which one element displaces another from a compound.
- 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'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...
- 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 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...
- Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...
Law of Conservation of Matter
There is no detectable change in the quantity of matter during an ordinary chemical reaction.
The scattering of light by colloidal particles.
Many representative elements attain at least a share of eight electrons in their valence shells when they form molecular or ionic compounds, there are some limitations.
Complex species that contain ammonia molecules bonded to metal ions.
A class of enzymes found in bacteria within root nodules in some plants, which catalyze reactions by which N2 molecules from the air are converted to ammonia.
A gas filled tube which discharges electriaclly when ionizing radiation passes through it.
Hydrolysis of esters in the presence of strong soluable bases.
In a cathode ray tube, the positive electrode. Electrode at which oxidation occurs.
A reaction that, once initiated, sustains itself and expands. This is a reaction in which reactive species, such as radicals, are produced in more than one step. These reactive species, radicals, propagate the chain reaction.
At constant temperature the volume occupied by a definite mass of a gas is inversely proportional to the applied pressure.
Refers to chemical similarities in the Periodic Table of elements of Period 2 to elements of Period 3 one group to the right, especially evident toward the left of the periodic table.
The smallest repeating unit of a substance. The molecule for nonionic substances
The properties of the elements are periodic functions of their atomic numbers.
The ability of a substance to be broken down into simpler substances by bacteria.
Second Law of Thermodynamics
The universe tends toward a state of greater diorder in spontaneous processes.
The prefix used to indicate that groups are located on the same side of a bon about which rotation is restricted.
An isotope of hydrogen whose atoms are twice as massive as ordinary hydrogen,deuterion atoms contain both a proton and a neutron in the nucleus.
Positively charged or electron-deficient.
The process by which solvent molecules pass through a semipermable membrane from a dilute solution into a more concentrated solution.
A class of silicate and aluminosilicate minerals with sheet-like structures that have enormous surface areas that can absorb large amounts of water.
