To find the mass of hydrogen needed to react with 40g of copper oxide (CuO), first calculate the molar mass of CuO. Then, use stoichiometry to determine the moles of CuO present in 40g. From the balanced chemical equation CuO + H2 -> Cu + H2O, you can determine the mole ratio between CuO and H2. Finally, use the molar mass of hydrogen to calculate the mass of hydrogen needed to react.
I think you mean how do you extract copper from copper oxide, if so here's your answer. Take your copper oxide and heat it with something that is more reactive than copper. Carbon is a good example. The more reactive carbon will oxidise, taking the oxygen from the copper oxide leaving copper. copper oxide + carbon --> copper + carbon dioxide 2Cu0 + C --> 2Cu + CO2
Copper oxide was added until no more would react to ensure that all the available hydrogen gas had been produced in the chemical reaction. This step allows for the maximum yield of hydrogen gas to be collected before reaching saturation.
Yes, copper and iron oxide can react with each other. When heated, copper can displace iron from iron oxide in a redox reaction, forming copper oxide and leaving metallic iron behind.
Yes, copper can react with oxygen to form copper oxide. This reaction typically results in a layer of black copper oxide forming on the surface of the copper.
Copper sulfate is the salt formed when copper oxide and sulfuric acid react together.

Copper oxide acts as an oxidizing agent in the test for carbon and hydrogen. It can react with the carbon and hydrogen in the organic compound to form carbon dioxide and water, respectively. By observing the change in color of the copper oxide, we can determine the presence of carbon and hydrogen in the compound.

It doesn't.
Yes, copper can react with oxygen to form copper oxide. This reaction typically results in a layer of black copper oxide forming on the surface of the copper.
Aluminium oxide doesn't react with hydrogen.
Copper sulfate is the salt formed when copper oxide and sulfuric acid react together.
Copper is a moderately reactive metal. It can react with oxygen to form copper oxide. It can also react with acids to form copper salts and hydrogen gas. Its reactivity can be increased in the presence of certain chemicals or conditions.
oxygen
It forms copper oxide
Copper oxide and sulfuric acid will react together to produce copper sulfate.
