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.
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 ...
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).
Plants may contain 25 to 50 leaves arranged in one or more rosettes at the upper end of the root. Taraxacum kok-saghyz can be differentiated from the common dandelion ( Taraxacum officinale ) by its generally smaller, grayish green leaves and hornlike structures on the bracts surrounding the bud.

Yttrium barium copper oxide (YBa 2 Cu 3 O 7) consists of both Cu(II) and Cu(III) centres. Like oxide, fluoride is a highly basic anion [19] and is known to stabilize metal ions in high oxidation states. Both copper(III) and even copper(IV) fluorides are known, K 3 CuF 6 and Cs 2 CuF 6, respectively. [1]
