The absolute entropy of a substance in its standard state at 298 K.
- 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?
- 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...
- 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...
- 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...
Any species that can make available a share in an electron pair.
Collision between molecules resulting in a reaction, one in which the molecules collide with proper relative orientations and sufficient energy to react.
Secondary Voltaic Cells
Voltaic cells that can be recharged, original reactanats can be regenerated be reversing the direction of the current flow.
Chemical Hygiene Plan (CHP)
A written program developed and implemented by an employer designating proceedures, equipment, personal protective equipment, and work practices that are capable of protecting employees from the health hazards presented by hazardous chemicals usid in that particular workplace.
Formula that indicates the actual number of atoms present in a molecule of a molecular substance.
Compounds that contain more than two elements but are named like binary compounds.
The ability of one liquid to mix with (dissolve in) another liquid.
Metal with low ionization energy that loses electrons readily to form cations.
Unsaturated hydrocarbons that contain one or more carbon-carbon triple bonds.
Equilibrium constant for the ionization of a weak electrolyte.
An aliphatic acid, many can obtained from animal fats.
The rate at which a particular substance will vapourize (evaporate) when compared to the rate of a known substance such as ethyl ether. This term is especially useful for health and fire-hazard considerations.
The percentage of the weak electrolyte that ionizes in a solution of given concentration.
The combination of critical temperature and critical pressure of a substance.
Absolute Entropy (of a substance)
The increase in the entropy of a substance as it goes from a perfectly ordered crystalline form at 0 °K (where its entropy is zero) to the temperature in question.
Entropy is a measure of the “dilution” of thermal energy.
Number of moles of solute per litre of solution.
A compound formed by interaction of sucrose with a metallic oxide, usually lime, and useful in the purification of sugar.
A cluster of atoms in a ferromagnetic substance, all of which align in the same direction in the presence of an external magnetic field.
The quantity of product formed by the interaction of two or more substances, generally expressed as a percentage of the quantity obtained to that theoretically obtainable.
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.
