Taraxacum officinale, the dandelion or common dandelion, [6] is a herbaceous perennial flowering plant in the daisy family, Asteraceae. The common dandelion is well known for its yellow flower heads that turn into round balls of many silver-tufted fruits that disperse in the wind. These balls are called "clocks" in both British and American ...
As a significant product of copper mining, copper(II) oxide is the starting point for the production of many other copper salts. For example, many wood preservatives are produced from copper oxide. [3] Cupric oxide is used as a pigment in ceramics to produce blue, red, and green, and sometimes gray, pink, or black glazes. [3]
The common name dandelion (/ ˈ d æ n d ə l aɪ. ən / DAN-də-ly-ən; from French dent-de-lion 'lion's tooth', referring to the jagged leaves) is also given to specific members of the genus. [8] Like other members of the family Asteraceae, they have very small flowers collected together into a composite flower head.
Rouge/crocus/colcothar – ferric oxide, formed by burning green vitriol in air. Stibnite – antimony or antimony trisulfide, ore of antimony. Turpeth mineral – hydrolysed form of mercury(II) sulfate. Verdigris – Carbonate of Copper or (more recently) copper(II) acetate. The carbonate is formed by weathering copper.
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and the atomic number of 29. It is easily recognisable, due to its distinct red-orange color.Copper also has a range of different organic and inorganic salts, having varying oxidation states ranging from (0,I) to (III).
The binomial name often reflects limited knowledge or hearsay about a species at the time it was named. For instance Pan troglodytes, the chimpanzee, and Troglodytes troglodytes, the wren, are not necessarily cave-dwellers. Sometimes a genus name or specific descriptor is simply the Latin or Greek name for the animal (e.g. Canis is Latin for ...
Taraxacum ceratophorum, also known as the horned dandelion, is a species of flowering plant within the genus Taraxacum and family Asteraceae. [1] This alpine species has a preference for mountainous habitat, where it can be found growing at elevations up to 3000 meters above sea level. [ 2 ]
Copper oxide is any of several binary compounds composed of the elements copper and oxygen. Two oxides are well known, Cu 2 O and CuO, corresponding to the minerals cuprite and tenorite, respectively. Paramelaconite (Cu 4 O 3) is less well characterized. [1] Copper oxide may refer to: Copper(I) oxide (cuprous oxide, Cu 2 O) Copper(II) oxide ...
