When copper is added to iodine, a reaction occurs in which the copper displaces the iodine from its compound forming copper iodide. This reaction is a single displacement reaction where the more reactive copper replaces the less reactive iodine in the compound. The chemical equation for this reaction is Cu + I2 → CuI
When copper is mixed with copper nitrate, a chemical reaction occurs where the copper in the copper nitrate displaces the copper in the solid copper, forming copper(II) nitrate and releasing nitrogen dioxide gas. This reaction is a redox reaction, where copper is oxidized and the copper ions in the solution are reduced.
When copper sulfate and iron are mixed, a redox reaction will occur. The iron will displace the copper in the copper sulfate solution, forming iron sulfate and copper metal. This reaction is a classic example of a displacement reaction.
Only copper is directly involved in the reaction, as it is the metal that is reacting with oxygen to form copper oxide. Oxygen is the other element involved in the reaction, but it is not part of the initial reactants.
Yes, when iron comes into contact with copper sulfate, a chemical reaction occurs where the iron displaces the copper in the compound, forming iron sulfate and copper. This reaction is known as a displacement reaction.
