The process in which a heavy nucleus splits into nuclei of intermediate masses and one or more protons are emitted.
- 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 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
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.
Solubility Product Constant
Equilibrium constant that applies to the dissolution of a slightly soluble compound.
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.
Electrolytic cell for the commercial electrolysis of molten sodium chloride. For further information see Electrochemistry or Fuel Cells.
Refers to crystals having the same atomic arrangement.
Amount of solute per unit volume or mass of solvent or of solution.
An orgainic ion carrying a positive charge on a carbon atom.
Substances that flow freely, gases and liquids.
How closely a measured value agrees with the correct value.
Description of the quantitative relationships among elements and compounds as they undergo chemical changes.
Liquids that, when cooled, apparently solidify but actually continue to flow very slowly under the influence of gravity e.g glass.
Adverse health effects resulting from skin exposure ot a substance.
Freezing Point Depression
The decrease in the freezing point of a solvent caused by the presence of a solute.ing Point
Pair of electrons involved in a covalent bond.
An instrument that measures the charge-to-mass ratio of charged particles.
Second Law of Thermodynamics
The universe tends toward a state of greater diorder in spontaneous processes.
A reaction in which two atoms or groups of atoms are added to a molecule, one on each side of a double or triple bond. Types of addition reaction include electrophilic, nucleophilic (polar) and free radical addition (non-polar).
Crystal Lattice Energy
Amount of energy that holds a crystal together, the energy change when a mole of solid is formed from its constituent molecules or ions (for ionic compounds) in their gaseous state.
A substance of a known high degree of purity that undergoes one invariable reaction with the other reactant of interest.
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.
