Not sure about your examples but electronegativity variance is a good rule of thumb for deciding ionic from covalent bonds.
Electronegativity variance less than 1.4, generally much less, indicates a covalent bonding.
Electronegativity variance greater than 1.4 indicates ionic bonding.

Is CuO classified as a solid?
Under normal circumstances, CuSO4, or is a solid. However, it can become a liquid if it is placed in a solution.
Copper 2 oxide formula?
Copper(II) oxide: CuO
What mass of CuO will be obatined by heating 12.5gm of copper carbonate?
12.5 (g CuCO3) = [12.5 (g CuCO3) / 123.555 (g/mol CuCO3)] = 0.1012 (mol CuCO3)0.1012 (mol CuCO3)* [1 (mol CuO) / (mol CuCO3)] = 0.1012 (mol CuO)= [0.1012 (mol CuO) * 79.545 (g/mol CuO)] = 8.047 g CuO = 8.05 g CuO
What do you get from Fe plus CuO?
2 Fe + 3 CuO -> Fe2O3 + 3 Cu
Why is the equation H2 O2H2O incorrect?
Well it fully depends on what type of copper you have. if you have Cu1+ then when you do an ionic equation and switch the ion charges, then the compound you would get would be Cu2O. If you had Cu2+ then the compound would end up being CuO. You cant just put two things together and assume its right. You have to do an ionic equation and then balance your reaction.
Ionic compound name for CuO?
CuO is copper (II) oxide, also known as cupric oxide.
Can Cs and O form a covalent bond?
Covalent bonds are formed between a metal and a non-metal. Co is cobalt, a metal, so it will react with O to form CuO, a compound with ionic bonds.
IS CuO Ionic or molecular?
ionic
Is CUO covalent or ionic?
Covalent bonds are between non-metals only. Ionic bonds are between non-metals and metals. Copper is a metal and oxygen is a non-metal; therefore, Copper II oxide is ionically bonded.
Is copper II hydroxide covalent?
Copper (II) oxide, CuO is a compound containing a metal - copper, and a non-metal - oxygen. It is therefore has ionic bonding. Remember: Metal - non-metal = ionic bonding Non-metal - non-metal = covalent bonding Metal - metal = metallic bonding
Does CuO have polar bond?
CuO has an ionic bond, so it would be considered polar.
What is The smallest whole-number ratio of the element in an ionic or covalent bond?
Emperical formula give the smallest whole number ratio of atoms in a compound
Is copper oxide CuO a compuond or a heterogeneous mixture?
CuO is a compound. It is not a mixture.
Is Cuo a ionic or molcular?
The simplest description is that it is ionic, and the argument is that the difference in electronegativity causes a full transfer of electrons. It is high melting solid and certainly i not molecular. As with many metal oxides the real bonding is somewhere between ionic and covalent, and this is particularly true for metals other than those in group1 and 2. I personally do not like the categorisation of compounds into ionic and molecular. Many macro crystalline solids are covalent.
Does copper and oxygen make a compound?
Yes... The compound is copper oxide CuO I think
Which ones in the chemical reaction 'CuO CO2---CuCO3' are ionic compounds?
CuO + CO2 -> CuCO3 CuO is copper oxide and is an ionic bond Cu(2+) and O(2-) CuCO3 is also an ionic bond, as one oxygen from copper oxide has joined with the covalently bonded carbon dioxide, CO2, to form carbonate, a polyatomic ion. Cu(2+) and CO3(2-)
What is a compound composed only of non metals?
Compounds that contain only non metal elements usually have covalent bonding and true molecules.
