  1. In crystallography, "general multiplicity" refers to the number of symmetry operations (such as rotations or reflections) that can be applied to a crystal lattice to generate equivalent positions.
  2. "Chemical occupancy" refers to the number of atoms occupying a specific position in the crystal lattice. It indicates the stoichiometry (ratio of different atoms) within the crystal structure.
  3. "Site multiplicity" refers to the number of equivalent sites (positions) within a crystal lattice that are indistinguishable based on the crystal's symmetry elements.
  4. "Occupation number" refers to the number of atoms or molecules occupying a specific site in the crystal lattice. It indicates if the site is fully occupied (1.0), partially occupied (less than 1.0), or vacant (0.0).

When are structural formulas used?

Structural formulas are used primarily for organic compounds for which molecular formulas correspond to more than one isomer, or for chemical discussions in which the shapes of molecules are important, such as crystallography.

Each mineral has a different formation?

Indeed, each different mineral has a different chemical composition and crystal structure. Sometimes you may have two minerals with the same chemical formula, but which differ in their crystallography. Calcite and Aragonite would be one example. Similarly several different minerals might form face-centred cubes, but differ in their chemistry.

When was the chemical engineering profession started?

The first degree courses in chemical engineering were taught in the 1880s, both in the UK and the US. It would take 20 years, however, before the discipline was recognized as an independent science, distinct from chemistry. The term "chemical engineer" was well established as a professional occupation by 1910. The first chemical engineering professional association, the Institution of Chemical Engineers, was formed in the UK in 1922.


Which methods you can use to determine the primary structure of an enzyme?

Off the top of my head: techniques such as chemical and enzymatic degredation (particularly if they are targeted) coupled with various analytical techniques particularly mass spectrometry and NMR. X-ray crystallography could also be used if the enzyme can be crystallised.


Which electron configurations indicates an atom with atomic number of 24?

[Ar]4s13d5 note it is NOT [Ar]4s23d4. The reason for this is to achieve maximum spin multiplicity and hence lowest energy, the first arrangement gives 6 half - filled orbitals (maximum spin multiplicity) whereas the 2nd arrangement gives on 4 half filled orbitals.


How many fire extinguishers should be in a house?

First determine the total square footage of both floors. Second, determine the hazard occupancy (low, moderate, or high) by reading examples written in the NFPA10, 2007 Edition, Standard For Portable Fire Extinguishers on page 10-23. If you are installing 10 lb. ABC Dry Chemical extinguishers (the most common type and size), most of them are UL rated at 4-A. A 4-A extinguisher will protect the following: low hazard occupancy - 11,250 sq. ft. ;ordinary hazard occupancy - 6,000 sq. ft. :high hazard occupancy - 4,000 sq. ft. Next divide your total square feet by the square feet of the occupancy hazard and you have your MINIMUM number of 4-A rated fire extinguishers required. You may have to add extinguishers due to the building layout. From any place in the building, you have to be able to walk to a fire extinguisher in no more than 75 feet (75 foot maximum travel distance). Lastly if there are any special hazards (computer room, electrical room, flammable liquids, etc.), they should be protected separately in addition to the building's fire extinguishers.


What chemistry can do to you?

I'm at the University of Glasgow and there you can study Forensic chemistry Medicinal Chemistry (which is the most popular) chemical physics and straight chemistry but within the straight chemistry there is inorganic, physical and organic and within that there is even more! magnetochemisty, crystallography, theoretical, solid state, catalysis, surface,radical chemistry, protein chemistry, radiochemistry and don't forget environmental chemistry. and there is so much more. Chemistry is one of the broadest sciences there is.
