QUESTION 1 The reаctiоns оf metаls with wаter and with dilute sulfuric acid can be used tо determine the order of reactivity of the metals. The table shows the reactions of four metals, W, X, Y and Z, with water and with dilute sulfuric acid. Metal Reaction with water Reaction with dilute sulfuric acid W no reaction no reaction X very slow reaction reacts quickly Y no reaction reacts slowly Z reacts quickly reacts violently 1 a What is the order of reactivity of these metals? List them from most reactive to least reactive. e.g W, X, Y, Z (1) 1b(i) State which metal, W, X, Y or Z, could be copper. (1) 1b(ii) State which metal, W, X, Y or Z, could be magnesium. (1) 1c A displacement reaction can also be used to decide the order of reactivity of two metals. State two observations made when an excess of magnesium powder is added to an aqueous solution of copper(II) sulfate. (2) [5]
