![]() ![]() The chemical equations for the reactions that will take place are as follows: They have to take part in a reaction with copper sulfate which is an aqueous solution and its metal ion is copper. For this experiment, the four metal powders given are magnesium, zinc, aluminium and iron. ![]() When the total energy given out is more than the energy used, the reaction is exothermic and its product is a very stable compound. The metal powder easily forms a compound with the non-metal ion of the compound and more energy is given out. This happens because the compound on the reactants side is quite unstable and thus breaks up easily and so much energy is not used up. In theory, when a more reactive metal takes part in a displacement reaction, the reaction is more vigorous and exothermic. When a displacement reaction occurs, heat energy is given out which means that the reaction is exothermic. ![]() Therefore in this reaction, a more reactive metal will displace the metal ion in the compound and thus it will be separated. This reaction is carried out using the metal powder given and a weak compound such as copper sulphate in which the metal ion is lower than the metal powder in the reactivity series. If there were four metal powders are given and their reactivity was to be found, then we could carry out a displacement reaction. We Will Write a Custom Essay Specifically ![]()
