W, X, Y and Z are four different metals commonly found in school laboratory. The table below lists the results of two experiments carried out using the metals or their oxides. Experiment Addition of metal no observable to iron(II) nitrate change solution Action of heat on oxide of metal W X Y formation of a colourless gas and change a clear solution no observable |change no observable formation of silvery grey coating on Z no observable change no observable change formation of Igreyish residue (a) Which is the least reactive metal? Explain briefly. (b) Explain why a colourless gas is formed when metal X is added to iron(II) nitrate solution. Write a chemical equation, including state symbols, for the reaction involved. (c) Name the type of reaction that takes place when metal Z is added to iron(II) nitrate solution. (d) What is the most suitable method for extracting metal W from its oxide ore? Write an equation for the reaction involved, assuming that the formula of the oxide of W is WO. (e) Arrange the four given metals, as well as iron, in descending order of reactivity. 2.
