Azurite has the formula Cu 3 (CO 3) 2 (OH) 2, with the copper(II) cations linked to two different anions, carbonate and hydroxide. It is one of two relatively common basic copper(II) carbonate minerals, the other being bright green malachite. Aurichalcite is a rare basic carbonate of copper and zinc. [8]
Azurite is a basic compound that is coordinated with copper. [1] Azurite was popular due to its stability in various light and atmospheric conditions, making it easy to store. [1] Although azurite is permanent in oil and tempura paint, it is darkened when exposed to sulfur; this can be seen in mural paintings that use azurite.
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
Azurmalachite is a mixture of azurite and malachite. [1] It is alternatively called azuromalachite, azurite-malachite and malachite-azurite. [2] Azurmalachite has a distinctive mottled green and blue coloration. It is relatively rare but can sometimes be found above copper deposits.
In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the applied forces and moments, and reactions, which act on the body(ies).
[2] Other blue minerals, such as the carbonate mineral, azurite , and the phosphate mineral, lazulite , may be confused with lazurite, but are easily distinguished with careful examination. At one time, lazurite was a synonym for azurite .
Tenorite with azurite from Nischne Tagilsk, Urals, Russia. Tenorite occurs in the weathered or oxidized zone associated with deeper primary copper sulfide orebodies. Tenorite commonly occurs with chrysocolla and the copper carbonates, azurite and malachite.
By this method, body diagrams can be derived by pasting organs into one of the "plain" body images shown below. This method requires a graphics editor that can handle transparent images, in order to avoid white squares around the organs when pasting onto the body image. Pictures of organs are found on the project's main page. These were ...
