"Here is another of the magical half-dozen. The range is purposefully broad. At 10 milligrams there have been some pretty rich +++ [nb 1] experiences, and yet I have had the report from one young lady of a 30 milligram trial that was very frightening. My first experience with 2C-E was really profound, and it is the substance of a chapter within ...
The mean score for all test takers from July, 2009, to July, 2012, was 526 with a standard deviation of 95. [7] After learning that test content from editions of the GRE® Biochemistry, Cell and Molecular Biology (BCM) Test has been compromised in Israel, ETS made the decision not to administer this test worldwide in 2016–17.
Reagents are "substances or compounds that are added to a system in order to bring about a chemical reaction or are added to see if a reaction occurs." [1] Some reagents are just a single element. However, most processes require reagents made of chemical compounds. Some of the most common ones used widely for specific reactive functions are ...
The anion [Ce(NO 3) 6] 2− has T h (idealized O h) molecular symmetry.The CeO 12 core defines an icosahedron. [4]Ce 4+ is a strong one-electron oxidizing agent.In terms of its redox potential (E° ≈ 1.61 V vs. N.H.E.) it is an even stronger oxidizing agent than Cl 2 (E° ≈ 1.36 V).

Biological specimens in an elementary school science lab. A biological specimen (also called a biospecimen) is a biological laboratory specimen held by a biorepository for research. Such a specimen would be taken by sampling so as to be representative of any other specimen taken from the source of the specimen. When biological specimens are ...
In chemistry, a reagent (/ r i ˈ eɪ dʒ ən t / ree-AY-jənt) or analytical reagent is a substance or compound added to a system to cause a chemical reaction, or test if one occurs. [1] The terms reactant and reagent are often used interchangeably, but reactant specifies a substance consumed in the course of a chemical reaction. [1]
Chemiluminescence (also chemoluminescence) is the emission of light (luminescence) as the result of a chemical reaction, i.e. a chemical reaction results in a flash or glow of light. A standard example of chemiluminescence in the laboratory setting is the luminol test. Here, blood is indicated by luminescence upon contact with iron in hemoglobin.
