What’s the difference? Copper and gold are different metal elements with different properties. The thermal conductivity of gold is 318W/mK, whereas the thermal conductivity of copper is slightly higher at 401W/mK. The electrical conductivity of copper is slightly higher at 5.96 x10 7 S/m than gold which is 4.11×10 7 S/m.

They are made up of atoms and molecules.
What happens when copper powder is heated in air * blue colored copper sulphate is formed black colored copper oxide is formed blue colored copper nitrate is formed pale green copper carbonate is formed
In addition, when the copper powder is heated in a porcelain dish, the surface of the copper powder will be coated with a black substance, because I would say that the copper oxide surface has been formed by oxidation. The black color is due to the formation of basic oxide (II) upon contact of copper with air.
What happens when dilute sulphuric acid is poured on a copper plate copper sulphate formed copper chloride formed hydrogen sulphide formed copper sulphide formed
Answer: Answer: Copper does not react in any way with dilute stomach acid. So there will be no reaction if you pour dilute sulfuric acid into a copper plate.
What are the important ores of copper How is copper extracted from copper pyrites
After roasting, the corresponding ore is mixed with coke and then smelted in a special blast furnace. The matte, somehow extracted from the blast furnace, is injected directly into the silica-coated converter.
