Carbon + Copper oxide -> Copper + Carbon dioxide
When malachite is heated, it decomposes into copper(II) oxide and carbon dioxide. The word equation for this reaction is: Copper(II) carbonate (malachite) → Copper(II) oxide + Carbon dioxide.
The word equation for the corrosion of copper is: Copper + Oxygen + Water → Copper Oxide.
The chemical formula for copper oxide is CuO.
The chemical equation is:Cu2CO3(H2O)----------------2 CuO + CO2 + H2O
The word equation for copper reacting with oxygen is: copper + oxygen → copper oxide.
When malachite is heated, it decomposes into copper(II) oxide and carbon dioxide. The word equation for this reaction is: Copper(II) carbonate (malachite) → Copper(II) oxide + Carbon dioxide.
CuCO3 ==> CO2 + CuO (heat is the catalyst, written above the arrow)
The word equation for the corrosion of copper is: Copper + Oxygen + Water → Copper Oxide.
The chemical formula for copper oxide is CuO.
The chemical equation is:Cu2CO3(H2O)----------------2 CuO + CO2 + H2O
The word equation for copper reacting with oxygen is: copper + oxygen → copper oxide.
Copper oxide reacts with sulfuric acid to form copper sulfate and water. The word equation is: Copper oxide + sulfuric acid → copper sulfate + water.
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
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)
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.
Copper oxide (CuO) reacts with hydrogen gas (H2) to form copper (Cu) and water (H2O). The word equation for this reaction is: copper oxide + hydrogen gas → copper + water.
When sodium carbonate is heated, it decomposes into sodium oxide and carbon dioxide. The word equation for this reaction is: Sodium carbonate → Sodium oxide + Carbon dioxide.
