Chemists have a handy way of talking amount these vast numbers of atoms—by using the rather unusual word mole. A mole of something (anything) has exactly 6.022 × 1023 particles in it, which is a short way of saying 602,200,000,000,000,000,000,000 or 602 billion trillion. This stran...
Emma Bernard, a fossil fish expert at the Museum, explains the reasons behind the unusual shape. What does a horn shark egg look like? Horn sharks lay eggs. The egg case is about 5 inches long and shaped like a spiral cork screw. The egg case is the color of kelp, so it is ...
F2. This is typically described in high-school chemistry as a simple example of covalent electron-sharing, but the purely covalent contribution to the bond turns out to be repulsive. The atoms can instead be considered to be held together ...
Discuss the significant and/or unusual properties of gallium. What are the applications for this element in today's world? What is the natural occurrence of this element? What gives carbon its unique characteristics? How is this connected to life? Define the characteristics of an acid. What are...
The chemical symbol for antimony is Sb, an unusual abbreviation using none of the letters in the elements name. This is common for elements known to different ancient civilizations. While the name antimony comes from Greek, the chemical symbol is based on the Latin name of stibium. ...
NPB or also known as N-Propyl bromide or 1-bromopropane, isa solventthat is used in metal cleaning, vapor degreasing, and dry cleaning. NPB is an organobromine compound that is colorless in its liquid state. NPB has a characteristic of hydrocarbon odor making it smell like an oil, gas, ...
I bought it because it was too unusual and pretty not to. I'm online trying to see what I got. And I can't believe what some folks are selling/paying for it! Oh how I love Trader Joe's! Looking forward to trying this pretty salt after I figure out what exactly I will be consum...
Among the 39 created element names, except for 綠 (lü, chlorine) and 溴 (xiu, bromine), 37 of them were phonetic transcripts. This approach was unusual to people of that particular era. Most Chinese peo- ple knew practically nothing about Latin alphabets. Very few of them could spell. ...
No unusual tools or equipment are needed to disassemble the typical plastic valve; with proper design considerations the seals and key parts can be replaced in the field with minimal downtime. The overall ease of service and installation does have its drawbacks, however, as most mechanical ...
This unusual halogen, having the formula BrCl, is a dark red liquid having a boiling point of 5 [degrees] C, a density of 2.34 and vapor pressure of 30 psig at 20 [degrees] C. Disinfection, taste, & odor control Molecular complexes of OC and CIF and BrCl has been observed and char...
