Nuclide that undergoes nuclear decay.
- 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...
- 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...
- 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...
- 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...
Free Energy, Gibbs Free Energy
The thermodynamic state function of a system that indicates the amount of energy available for the system to do useful work at constant T and P.
Forces of attraction between a liquid and another surface.
Process that occurs in electrolytic cells.
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.
A small patch of photographic film worn on clothing to detect and measure accumulated incident ionizing radiation.
The amount of water that would absorb the same amount of heat as the calorimeter per degree temperature increase.
The degree of polymerization, the average number of monomer units per polymer unit.
Involves a change in the composition of a nucleus and can evolve or absorb an extraordinarily large amount of energy.
An instrument that measures the charge-to-mass ratio of charged particles.
A catalyst that exists in a different phase (solid, liquid or gas) from the reactants, a contact catalyst.
Reactions in which oxidation and reduction occur, also called redox reactions.
The study of rates and mechanisms of chemical reactions and of the factors on which they depend.
Bonding of atoms of the same element into chains or rings.
The bonding together of atoms of the same element to form chains.
The ability of an element to bond to itself.
Electrochemical cells in which electrical energy causes nospontaneous redox reactions to occur. An electrochemical cell in which chemical reactions are forced to occur by the application of an outside source of electrical energy.
A salt containing an ionizable OH group.
Redox reactions in which the oxidizing agent and the reducing agent are the same species.
The combination of critical temperature and critical pressure of a substance.
Method of Initial Rates
Method of determining the rate-law expression by carrying out a reaction with different initial concentrations and analyzing the resultant changes in initial rates.
Chemical bond formed by the sharing of one or more electron pairs between two atoms.
Maximum amount of a specified product that could be obtained from specified amounts of reactants, assuming complete consumption of limiting reactant according to only one reaction and complete recovery of product.
