Since there are two valence states for copper, Cu+ and Cu2+, there are two compounds formed from copper and oxygen:
The word equations for the reaction between copper and oxygen is copper+oxygen= copper oxide.
There are two possibilities. Cuprous Oxide is Cu2O - a red powder. Cupric Oxide is CuO - a black powder.
These reactions are:
4 Cu(I) + O2 = 2 Cu2O
2 Cu(II) + O2 = 2 CuO
copper oxide is the product
copper+oxygen-----copper oxide
copper + oxygen = copper oxide.
copper
The chemical formula for copper oxide is CuO.
Copper oxide+ Sulphuric acid ----> copper sulphate +water
HCL and copper oxide = Copper chloride+water
This will depend upon which version of copper oxide you have - copper I oxide or copper II oxide. For copper I oxide: H2SO4 + Cu2O --> Cu2SO4 + H2O For copper II oxide: H2SO4 + CuO --> CuSO4 + H2O
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.
The chemical formula for copper oxide is CuO.
Copper oxide+ Sulphuric acid ----> copper sulphate +water
HCL and copper oxide = Copper chloride+water
The balanced equation for copper(II) oxide and potassium chloride is CuO + 2KCl → CuCl2 + K2O When copper(II) oxide reacts with potassium chloride then it forms copper(II) chloride and potassium oxide.
This will depend upon which version of copper oxide you have - copper I oxide or copper II oxide. For copper I oxide: H2SO4 + Cu2O --> Cu2SO4 + H2O For copper II oxide: H2SO4 + CuO --> CuSO4 + H2O
Here are the equations for the thermal decomposition of copper carbonate (notice that a metal oxide is formed, just as it was with calcium carbonate): Copper carbonate → copper oxide + carbon dioxide CuCO3 → CuO + CO2
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.
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 chemical reaction is:CuO + H2SO4 = CuSO4 + H2O
Yes, if copper is exposed to wood, it decomposes rather quickly.
CuO + H2 ----> Cu + H2O
Assuming it's copper(II) oxide, the equation for that reaction is: CuO + H2 --> H2O + Cu. Reactants: copper oxide and hydrogen gas. Products: Water and copper. Elements present: hydrogen, copper. Compounds present: copper oxide, water. Metals: copper. Non-metals: hydrogen.
