A method used to determine the molecular weights of volatile liquids.
- 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?
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
Reactions in which one element displaces another from a compound.
The mass of one formula unit of a substance in atomic mass units.
Reaction in which two substances (elements or compounds) combine to form one compound.
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.
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.
A substance that produces OH (aq) ions in aqueous solution. Strong soluable bases are soluble in water and are completely dissociated. Weak bases ionize only slightly.
The point at which an indicator changes colour and a titration is stopped.
Amine in which the nitrogen is part of a ring.
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.
A white, needlelike, crystalline, water-soluble solid or syrup, C6H10O8, usually made by the oxidation of cane sugar, glucose, or starch by nitric acid. Also called "Glucaric acid."
Equilibrium or Chemical Equilibrium
A state of dynamic balance in which the rates of forward and reverse reactions are equal, the state of a system when neither forward or reverse reaction is thermodynamically favored.
Rate of Reaction
Change in the concentration of a reactant or product per unit time.
An oxidizing or reducing agent, who's mass gains (oxidizing agents) or loses (reducing agents) 6.022 x 1023 electrons in a redox reaction.
The mass of an acid or base that furnishes or reacts with 6.022 x 1023 H3O+ or OH- ions.
Stream of positively charged particles (cations) that moves toward the negative electrode in cathode ray tubes, observed to pass through canals in the negative electrode.
The pressure required to liquefy a gas (vapor) at its critical temperature.
Group of atoms remaining after a hydrogen atom is removed from the aromatic system.
Conjugate Acid-base Pair
In Bronsted-Lowry terminology, a reactant and product that differ by a proton, H+.
A substance that cannot be decomposed into simpler substances by chemical means.
The percent of a specified compound or element in an impure sample.
Solution in which no more solute will dissolve.
