The reaction for the reduction of copper oxide by hydrogen is as follows:
CuO(s) + H2(g) -> Cu(s) + H2O(g)
When copper oxide reacts with hydrogen, it forms copper metal and water. The balanced chemical equation for this reaction is: CuO + H2 → Cu + H2O. This is a reduction-oxidation (redox) reaction where copper oxide is reduced and hydrogen is oxidized.
Heating copper in an atmosphere of hydrogen will cause a reaction between copper oxide (CuO) and hydrogen gas (H2), resulting in the reduction of copper oxide to copper metal and the formation of water (H2O). This reaction effectively removes the oxygen from the copper oxide, leaving behind pure copper metal.
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.
The products of the reaction between copper sulfate and hydrogen peroxide are copper oxide, water, and oxygen gas. Specifically, the copper sulfate is reduced to copper oxide, while hydrogen peroxide is decomposed into water and oxygen gas.
When hydrogen gas passed over heated cupric oxide, the hydrogen is oxidized and displaces copper from the copper oxide as metallic copper, because hydrogen is higher than copper in the electromotive series. Water vapor is also produced by the reaction.
When copper oxide reacts with hydrogen, it forms copper metal and water. The balanced chemical equation for this reaction is: CuO + H2 → Cu + H2O. This is a reduction-oxidation (redox) reaction where copper oxide is reduced and hydrogen is oxidized.
When copper oxide is added to hydrogen, a redox reaction occurs. The color change observed is from black copper oxide to reddish-brown copper metal, indicating the reduction of copper oxide to copper metal by hydrogen gas.

it is a reduction reaction
because copper is located below hydrogen in reactivity series, thus hydrogen can reduce copper oxide which mean it undergo reduction reaction (loss of oxygen) CuO + H2 → Cu + H2O while, hydogen can't reduce magnesium because magnesium is located higher than hydrogen in reactvity series. it must be added with oxygen which mean it undergo oxidation reaction (gain oxygen) 2Mg + O2 → 2MgO i hope this will help u a lot ^_^

Heating copper oxide with carbon (in the form of coal or charcoal) causes a reduction reaction, where carbon removes oxygen from copper oxide to produce carbon dioxide and leave behind pure copper. This process is known as a reduction reaction, where carbon acts as a reducing agent to extract copper from its oxide form.
When hydrogen gas passed over heated cupric oxide, the hydrogen is oxidized and displaces copper from the copper oxide as metallic copper, because hydrogen is higher than copper in the electromotive series. Water vapor is also produced by the reaction.
The ionic equation for the reduction of copper sulfate (CuSO4) to copper oxide is: Cu^2+ + 2e^- → Cu This equation represents the reduction half-reaction where copper ions (Cu^2+) gain two electrons to form solid copper (Cu). The formation of copper oxide involves further reactions and would require a more comprehensive equation.
No. Copper oxide is just copper and oxygen. It is generally green in color and is often seen as weathering or corrosion on copper. Hydrogen is an element and is not part of copper oxide.
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.
