Also, it is found in minerals in which the silver sulfide is combined with the sulfides of other metals. Approximately three-quarters of the silver produced is a by-product of the extraction of other minerals, mainly copper and lead. Ancient civilizations such as Mesopotamia, the Egyptians, ...
Copper plating: mainly enhanced conductivity, corrosion resistance, gloss, for decoration. Nickel plating: mainly used on decorations Lustrous and corrosion-resistant; used in place of copper. Tin: usually used in industrial food containers, anti acid, resistant to sulfide, not easy to cause ...
the chemical symbol S[1, 2, 3]. Although pure sulfur is odorless, the bad smell linked with the element comes from some of its compounds, including hydrogen sulfide (H2S) that produces the “rotten egg” smell and mercaptans (an organic compound) that gives the defensive odor in skunks[...
Copper readily forms simplebinary compounds, which are chemical compounds consisting of only two elements. Examples of such compounds include copper oxide, copper sulfide, and copper chloride. Copper also forms complexes, organometallic compounds, and other compounds containing multiple atoms. Sources Hammo...
Cobalt naturally occurs in combination with other elements in the mineral ores like cobaltite (a sulfide containing cobalt, arsenic, iron, and nickel), erythrite (hydrated cobalt arsenate), and skutterudite (cobalt arsenate)[1]. It is generally obtained as a byproduct of copper and nickel mining...
Write the formula for tin(IV) phosphate. Identify the symbol and charge of the ions in this compound.Is the compound ammonium sulfide ionic, molecular, or an acid? Write its formula.Write the formula for iron(III) phosphide. Identify the symbol and charge of ...
As a result of its high affinity for oxygen, the element is used as a deoxidizer in non-ferrous metals like vanadium[3]. Yttrium is used in lithium iron phosphate batteries for increasing their capacity and durability[7]. Yttrium-90, a radioisotope of Y, can be useful for radiation therapy...
It is used in catalytic converters because it helps reduce automobile exhaust emissions[1]. Cerium oxide nanoparticles are added to diesel for reducing the emission of soot and improving engine performance of vehicles[5]. Cerium sulfide is non-toxic by nature and is used as a coloring pigment ...
Some important examples are galena (lead sulfide, PbS), blende (zinc sulfide, ZnS), pyrite (iron disulfide, FeS2), chalcopyrite (copper iron sulfide, CuFeS2), gypsum (calcium sulfate dihydrate, CaSO4∙2H2O) and barite (barium sulfate, BaSO4). The sulfide ores are valued chiefly for their...
High-grade or enriched stibnite reacts directly with scrap iron in the molten state, liberating antimony metal. The metal can also be obtained by conversion of stibnite to the oxide, followed by reduction with carbon. Sodium sulfide solutions are effective leaching agents for the concentration of ...
