Cu2 should be '2Cu' ( two uncombined atoms of copper.)
O2- should be 'O2; ( 2 combined atoms of oxygen).
When heated
2Cu(s) + O2(g) = 2CuO(s)
CuO is copper oxide and appears as a black solid.
Yes, CuO is an ionic compound. It is composed of a metal (copper, Cu) and a non-metal (oxygen, O) which form an ionic bond through the transfer of electrons. Copper gives up electrons to oxygen, resulting in the formation of positively charged copper ions (Cu2+) and negatively charged oxide ions (O2-).
The chemical formula for the compound formed between rubidium and oxygen is rubidium oxide - Rb2O.
O2 is a molecule made up of two oxygen atoms. Oxygen itself is an element, but when it combines with another oxygen atom to form O2, it is considered a molecule.
The Cr3+ ion has a +3 charge, while the O2- ion has a -2 charge. To form a neutral compound, we need two O2- ions to balance the charge of one Cr3+ ion. Therefore, the ions combine in a 1:2 ratio to produce the ionic compound chromium oxide (Cr2O3).
The covalent compound O2 is called oxygen gas.

i really dont know or care
The chemical formula for the compound formed between rubidium and oxygen is rubidium oxide - Rb2O.
No. CO2 is carbon dioxide, which is a compound of carbon and oxygen. It is usually formed by a reaction between oxygen and carbon or a carbon contain compound. Oxygen is a single element which is usually found in the form of O2.
O2 is a molecule made up of two oxygen atoms. Oxygen itself is an element, but when it combines with another oxygen atom to form O2, it is considered a molecule.
Cu2+ + O2- + H+ + Cl- = Cu2+ + 2 Cl- + H2O
The Cr3+ ion has a +3 charge, while the O2- ion has a -2 charge. To form a neutral compound, we need two O2- ions to balance the charge of one Cr3+ ion. Therefore, the ions combine in a 1:2 ratio to produce the ionic compound chromium oxide (Cr2O3).
The reaction is between Mg and O2. 2Mg+O2->2MgO
No, O2 is a molecule. However there are oxide ion (O2-), the peroxide ion (O22-), and the superoxide ion (O2-).
The covalent compound O2 is called oxygen gas.
O2 is not a compound , it is the element oxygen.
The combination of potassium (K) and oxygen (O2) produces K2O (potassium oxide). The balanced equation is 2K + O2 ==> K2O. The answer provided previously is incorrect. The compound KO does not exist.
