Copper(I) acetylide, or cuprous acetylide, is a chemical compound with the formula Cu2C2, known at least since 1856. In the common form (a monohydrate with formula Cu
2C
2.H
2O) it is a reddish solid, that easily explodes when dry.
Copper acetylide is a metal acetylide, a salt of the acetylide anion C2−
2 and the copper(I) cation Cu+
. It is similar to silver acetylide and calcium carbide, though it is not called carbide in literature.
Copper acetylide can be prepared by passing acetylene gas through copper(I) chloride solution in the presence of ammonia:
The acetylide then separates as a reddish precipitate.
When dry, copper acetylide is a heat and shock sensitive high explosive, more sensitive than silver acetylide.
Copper acetylide can form inside pipes made of copper or an alloy with high copper content, which may result in violent explosion. This was found to be the cause of explosions in acetylene plants, and led to abandonment of copper as a construction material in such plants. Copper catalysts used in petrochemistry can also possess a degree of risk under certain conditions.
Copper is a chemical element with symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a reddish-orange color. It is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys.
Copper is found as a pure metal in nature, and this was the source of the first metal to be used by humans, ca. 8,000 BC; it was the first metal to be smelted from its ore, ca. 5,000 BC; it was the first metal to be cast into a shape in a mold, ca. 4,000 BC; and it was the first metal to be purposefully alloyed with another metal, tin, to create bronze, ca. 3,500.
In the Roman era, copper was principally mined on Cyprus, the origin of the name of the metal from aes сyprium (metal of Cyprus), later corrupted to сuprum, from which the words copper (English), cuivre (French), Koper (Dutch) and Kupfer (German) are all derived. Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as azurite, malachite and turquoise and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris (or patina). Decorative art prominently features copper, both by itself and in the form of pigments.
Agkistrodon contortrix mokasen is a venomous pit viper subspecies found in the eastern United States.
The northern copperhead grows to an average length of 61-91 cm (24-36 in), with a maximum of 135 cm (53 in).
The dorsal scales are weakly keeled. The anal plate is single. The subcaudals are single, at least anteriorly.
The color pattern consists of an hourglass pattern that runs the length of the body. From above, a series of dark chestnut crossbands look narrow in the center and wider on the sides. Between the crossbands, small dark spots are often present. There are dark rounded spots at the sides of the belly. The head is a copper-red color. Juvenile specimens are lighter in color, have a yellow tail tip, and a narrow dark line that runs through the eye that divides the darker head from the lighter colored labial scales.

Copper is a reddish-colored metallic element, widely used in manufacturing and industry.

Demand for copper is surging. The red metal, considered a barometer for economic health, is a vital component for the construction and defense industries as well as a key ingredient in electric cars, wind turbines and the power grid. Offshore wind, for example, requires about “three times as much copper as does coal-fired power generation in terms of tons per gigawatt of capacity.” But mining companies are having a hard time keeping up. Globally, existing mines and projects under construction will meet only 80% of copper needs by 2030. To keep up with demand the industry is faced with a number of obstacles. including the shortage of mining workers, navigating regulatory hurdles as well as pushback from local stakeholders. So what impact will the looming global copper shortage have on the t...

Nitric acid is one of the few acids that can react with copper. But oddly enough, it doesn't work well when the acid is pure. This is because of something called passivation where layer of oxidized copper forms and it covers the surface and protects the copper. To get it going, I have to add some water, which will dissolve the protective layer and let the acid attack it. This more dilute acid can completely shred all the metal until it completely dissolves. #shorts

XXIX (TSX-V:XXIX) is advancing its Opemiska and Thierry Copper projects, two major Canadian copper assets. The Opemiska Project, Canada's highest-grade copper resource, spans 13,000 hectares in Quebec's Chapais-Chibougamau region, with strong infrastructure and nearby access to the Horne Smelter. A January 2024 resource update reported a 16% increase in contained Copper Equivalent (CuEq) and a 10% grade boost, including 87.3 million tonnes at 0.93% CuEq (Measured & Indicated) and additional Out of Pit resources. The Thierry Project in Ontario, covering 7,907 hectares, includes the Thierry Underground (K2) and K1 Open Pit deposits, with NI 43-101-compliant resources and historical production. Located near vital infrastructure, Thierry is a core asset as copper prices rise, positioning XXIX...

In this video I am handling two baby Copperhead snakes that belong to my homie Marcus. Copperhead snakes are native to Texas. The eastern copperhead (Agkistrodon contortrix), also known as the Copperhead, is a species of venomous snake, a pit viper, endemic to eastern North America; it is a member of the subfamily Crotalinae in the family Viperidae.The eastern copperhead has distinctive, dark brown, hourglass-shaped markings, overlaid on a light reddish brown or brown/gray background. The body type is heavy, rather than slender. Neonates are born with green or yellow tail tips, which progress to a darker brown or black within one year. Adults grow to a typical length (including tail) of 50–95 cm (20–37 in). In most of North America, it favors deciduous forest and mixed woodlands. It may oc...
