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.
The compound formed between Cu2+ and O2- ions is copper(II) oxide (CuO). In this compound, the copper ion has a charge of +2 while the oxygen ion has a charge of -2, resulting in a 1:1 ratio of copper to oxygen atoms.

Is CuO ionic compound?
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-).
What is the chemical formula for the compound formed between rubidium and oxygen?
The chemical formula for the compound formed between rubidium and oxygen is Rb2O.
Is o2 an element or a compound?
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 ions Cr3 plus and O2- combine to form the ionic compound chromium oxide. In what proportions do these ions combine to produce a neutral compound?
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).
What are incorrect formulas for elements Ar2 Fe Cu2 I2 O2?
Ar2 (argon) is incorrect as noble gases do not form stable diatomic molecules. Cu2 (copper) is incorrect as copper typically forms ions with a +1 or +2 charge, not as a diatomic molecule. I2 (iodine) and O2 (oxygen) are correct formulas for elements iodine and oxygen respectively.
Is CuO ionic compound?

Copper gives up electrons to oxygen, resulting in the formation of positively charged copper ions (Cu2+) and negatively charged oxide ions (O2-).
What is the chemical compound for oxygen?
The chemical compound for oxygen is O2, which means that two oxygen atoms are bonded together. This is the form of oxygen that we breathe in the air.
What is the chemical formula for the compound formed between rubidium and oxygen?
The chemical formula for the compound formed between rubidium and oxygen is Rb2O.
Is CO2 desame with oxygen?
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.
Is o2 an element or a compound?
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.
What is the complete ionic equation for copper II oxide plus hydrochloric acid yield copper II chloride plus water?
Cu2+ + O2- + H+ + Cl- = Cu2+ + 2 Cl- + H2O
The ions Cr3 plus and O2- combine to form the ionic compound chromium oxide. In what proportions do these ions combine to produce a neutral compound?
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).
If Mg reacts with O the compound is MgO?
Yes, when magnesium (Mg) reacts with oxygen (O), it forms magnesium oxide (MgO) as the compound.
Is 02 binary compound?
No, "02" is not a binary compound. Binary compounds are chemical compounds composed of two different elements. "02" is a combination of oxygen atoms rather than distinct elements.
What are incorrect formulas for elements Ar2 Fe Cu2 I2 O2?
Ar2 (argon) is incorrect as noble gases do not form stable diatomic molecules. Cu2 (copper) is incorrect as copper typically forms ions with a +1 or +2 charge, not as a diatomic molecule. I2 (iodine) and O2 (oxygen) are correct formulas for elements iodine and oxygen respectively.
What is the name of the covalent compound o2?
The covalent compound O2 is called oxygen gas.
What does potassium and oxygen form what ionic compound?
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.
