Question

Metal X is more reactive than metal Y. Metal Y is more reactive than metal Z. Which statement is correct? (1 mark)

Answer 1

The correct answer is option B) ie When metal X is placed in a solution of Z sulfate, a reaction occurs.

• The metals in the reactivity series are ordered in descending order of reactivity.
• The difference in stability between metals' electron configurations as atoms and as ions accounts for their reactivity. They will all react to produce positive ions because they are all metals.
• In this question, this is given that X is more reactive than Y which is more reactive than Z
• So, we can place them in reactivity series as X>Y>Z
• This means that X can displace Y and Z . Y can displace Z. Z cannot displace any of the other two.

Hence, the correct answer is option B) When metal X is placed in a solution of Z sulfate, a reaction occurs.
