(d) Reactivity series question 1
The reactions of metals with water and with dilute sulfuric acid can be used to 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.
Question (a)
(a)
What is the order of reactivity of these metals?
[ 1 ]
Question (b)
(b)
State which metal, W, X, Y or Z, could be copper.

Question (c)
(c)
State which metal, W, X, Y or Z, could be magnesium.
[ 1 ]
Question (d)
(d)
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.

(d) Reactivity series question 2
A student investigates the reaction between zinc and copper(II) sulfate solution.
This is the equation for the reaction.
This is the student's method.
Step 1 add of copper(II) sulfate solution to a glass beaker
Step 2 record the temperature of the solution
Step 3 add between 5 g and 6 g of zinc powder (an excess) and stir the mixture
Step 4 record the highest temperature reached
State the colour change in the solution.
