## Related Questions   The balanced symbol equation for copper II oxide reacting with hydrogen is Cu + H2O. This reaction will create copper and water as a result. The word equations for the reaction between copper and oxygen is copper+oxygen= copper oxide.   Reacting it with Oxygen or an oxidizing agent 2Cu + O2 ---&gt; 2CuO Copper + Oxygen ---&gt; Copper Oxide Presumably burning in an oxygen-rich atmosphere, it is chemically reacting with oxygen to form copper oxide.    Since there are two valence states for copper, Cu+ and Cu2+, there are two compounds formed from copper and oxygen:Copper (I) Oxide = Cu2O (equation: 4Cu + O2 --> 2Cu2O)Copper (II) Oxide = CuO (equation: 2Cu + O2 --> 2CuO) There are two different copper oxide formula's:2Cu + O2 -> 2CuO (black Copper(II) oxide)or4Cu + O2 -> 2Cu2O (red Copper(I) oxide) There are two different copper oxide formula's:2Cu + O2 -> 2CuO (black Copper(II) oxide)or4Cu + O2 -> 2Cu2O (red Copper(I) oxide)Copper(II) = Cu2+Oxide = O2-CuO or copper(II) oxide 2CuS + 3O2 ---&gt; 2CuO + 2SO2 Copper Sulphide + Oxygen ---&gt; Copper Oxide + Sulphur dioxide  Copper oxide consists of copper and oxygen hence the name copper oxide.    Solid copper heated with oxygen in air produces copper (II) oxide. 2Cu(s) + O2(g) + heat --&gt; 2CuO(s) if you mix copper and oxygen you get Copper oxide ! Oxide is not an element . Copper plus oxygen eaquals copper oxide .Pure copper exposed to oxygen turns greenish . ###### Metal and AlloysElements and CompoundsScienceAcids and BasesChemistryPeriodic Table Copyright © 2020 Multiply Media, LLC.
