oxygen
Copper oxides are Cu2O - copper(I) oxide and CuO - copper(II) oxide.
Copper plus oxygen react to form copper oxide. This reaction can be represented by the chemical equation: 4Cu + O2 → 2Cu2O.
Oxide is not an element . Copper plus oxygen eaquals copper oxide .Pure copper exposed to oxygen turns greenish .
copper oxide.......CuO
There are two different copper oxide formula's:2Cu + O2 -> 2CuO (black Copper(II) oxide)or4Cu + O2 -> 2Cu2O (red Copper(I) oxide)
The word equation for copper reacting with oxygen is: copper + oxygen → copper oxide.
The chemical formula of cupric oxide is CuO.
I know that carbon plus oxygen equals iron and iron is what kills stars...
This is a chemical reaction known as a displacement reaction. Zinc has a higher reactivity than copper, so when zinc is added to copper oxide, it displaces copper from the compound forming zinc oxide and copper metal. This reaction occurs because metals higher in the reactivity series can displace metals lower in the series from their compounds.
Copper oxide reacts with carbon dioxide to form copper carbonate. This reaction can be represented by the chemical equation: CuO + CO2 -> CuCO3.
As in most chemical reactions, an increase in temperature increases the rate of reaction between copper oxide and acid.
Balanced equation: CuO + 2HCl --> CuCl2 + H2O Word equation: One mole of copper (II) oxide plus two moles of hydrochloric acid produces (or yields) one mole of copper (II) chloride plus one mole of water.
