ammonium salt and alkali metal carbonate aqueous solution to form copper complexes. When boiled in water or heated in a strong alkali solution, brown copper oxide can be generated, which is decomposed into black copper oxide at 200°C. It is unstable in a hydrogen sulfide atmosphere and can ...
A. copper sulfate B. copper hydroxide C. copper D. copper carbonate 相关知识点: 试题来源: 解析 C。加热氧化铜与氢气时,黑色氧化铜变红,是因为生成了铜单质。A 选项硫酸铜不是这个反应的产物。B 选项氢氧化铜也不是此反应的产物。D 选项碳酸铜同样不是。反馈...
When Cu(OH)2 (s) is heated, copper(ll) oxide and water are formed. Write the balanced equation for the reaction. Decomposition Reaction: In the decomposition reaction, a compound is converted to two or more simple compounds by heating or using any ca...
A green layer of verdigris (copper carbonate) can often be seen on old copper structures, such as the roofing of many older buildings[17] and the Statue of Liberty.[18] Copper tarnishes when exposed to some sulfur compounds, with which it reacts to form various copper sulfides.[19] ...
The oxidation of copper by making the basic copper carbonate under non-reducing environment in the electric furnace, heated for 20 minutes at a temperature of 400 ℃, the thermal decomposition. 所得氧化铜粉在将X射线衍射光谱(-1,1,1)面的峰强设为I,结晶完成的基准氧化铜粉的X射线衍射光谱(-1,...
Other important ores are chalcocite, or copper glance, a shiny lead-gray copper sulfide; bornite, a lustrous reddish-brown sulfide of copper and iron; cuprite, a red cuprous oxide ore; and malachite, a bright green carbonate ore. Azurite is a blue crystalline basic carbonate of copper found...
Air & Water ReactionsSolid pieces are very slowly oxidized by air to give a green basic carbonate. Solid pieces become covered by a black oxide when heated in air. Insoluble in water. Reactivity ProfileCopper combines violently with chlorine trifluoride in the presence of carbon [Mellor 2, Supp...
