Water is the chemical substance with chemical formula H 2 O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. [26] Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color.

Water chemistry analyses are carried out to identify and quantify the chemical components and properties of water samples. The type and sensitivity of the analysis depends on the purpose of the analysis and the anticipated use of the water. Chemical water analysis is carried out on water used in industrial processes, on waste-water stream, on ...

Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
Essequibo was founded by colonists from the first Zeelandic colony, Pomeroon conquered in 1581, which had been destroyed by Spaniards and local warriors around 1596. Led by Joost van der Hooge, the Zeelanders founded Fort Kyk-Over-Al in the Essequibo river (actually a side-river called the Mazaruni). This location was chosen because of its ...
The lab notebook is usually written as the experiments progress, rather than at a later date. In many laboratories, it is the original place of record of data (no copying is carried out from other notes) as well as any observations or insights. For data recorded by other means (e.g., on a computer), the lab notebook will record that the data ...
