Hydrocarbons that contain double or triple carbon-carbon bonds.
- 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...
Reaction of a substance with water.
A term used to describe molecules and polyatomic ions that have one atom in the center and four atoms at the corners of a square.
Emission of an electron from the surface of a metal caused by impinging electromagnetic radiation of certain minimum energy, current increases with increasing intensity of radiation.
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.
Hydrocarbon derivative containing an [OH] group bound to an aromatic raing.
The process in which a heavy nucleus splits into nuclei of intermediate masses and one or more protons are emitted.
Substances that flow freely, gases and liquids.
Chain Termination Step
The combination of two radicals, which removes the reactive species that propagate the change reaction.
Compounds that contain more than two elements but are named like binary compounds.
Homogeneous mixture of two or more substances.
The vapor pressure of a solvent in an ideal solution decreases as its mole fraction decreases.
A method of purifying a bar of metal by passing it through an induction heater, this causes impurties to move along a melted portion. This method applies the fact when a metal crystallizes on cooling, impurities are automatically expelled as they do not form part of the crystal.
Group VIIA elements: F, Cl, Br, I
A nuclear reactor that produces more fissionable nuclear fuel than it consumes.
Transition State Theory
Theory of reaction rates that states that reactants pass through high-energy transition states before forming products.
Law of Definite Proportions (Law of Constant Composition)
The law stating that a pure substance will always have the same percent by weight. Different samples of a pure compound always contain the same elements in the same proportions by mass.
High energy particles or rays emitted during the nuclear decay processes.
A positive ion, an atom or group of atoms that has lost one or more electrons.
An insoluble solid formed by mixing in solution the constituent ions of a slightly soluble solution.
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.
