Copper and oxygen multivalent metal ions ionic compounds?
Copper and oxygen can form various multivalent metal ions in ionic compounds. For example, copper(I) oxide (Cu₂O) and copper(II) oxide (CuO) are ionic compounds where copper exists in different oxidation states. These compounds are formed by the reaction of copper ions with oxygen ions to achieve stability through the transfer of electrons.
How can you be sure that the oxides of copper are different from compounds?
Oxides of copper are compounds !
Which is more stable zinc II compounds or copper II compounds?
copper II compounds are more stable because it is hard
How do elements occur?
As elements or as compounds For example, copper occurs in its elemntal form (native copper) and as various compounds (copper sulphide, copper sulphate etc)
Which two compounds are in copper oxide?
copper and oxygen
What is the solubility of copper iodide in water and how does it compare to other copper compounds?
The solubility of copper iodide in water is low, with only a small amount able to dissolve. Compared to other copper compounds, copper iodide is less soluble in water than some other copper compounds like copper sulfate or copper chloride.
What are the formulas for the compounds copper(I)?
Copper(I) oxide: Cu2O Copper(I) chloride: CuCl Copper(I) sulfide: Cu2S
Why are compounds of zinc white but compounds of copper have color?
Compounds of zinc are white because zinc atoms do not absorb visible light in the same way that copper atoms do. Copper compounds have color because copper atoms absorb certain wavelengths of visible light, leading to the perception of color in the compound. This difference in electronic structure is responsible for the variation in color between compounds of zinc and copper.
Why do copper compounds usually appear colourless although copper is a transition element?
Sorry, but most copper compounds are some shade of blueor green, not colorless at all!
Does copper form new compounds?
Yes, copper sulphate for one.
What are some common compounds in which copper is found?
Some common compounds in which copper is found include copper sulfate, copper oxide, copper carbonate, and copper hydroxide. Copper is also commonly found as a component in minerals like chalcopyrite and malachite.
What are the compounds of copper?
Some common compounds of copper include copper(II) sulfate, copper(II) chloride, copper(II) oxide, and copper(II) nitrate. Copper also forms compounds with other elements such as oxygen, sulfur, and carbon.
