Answer the question given below:
Arjun is given three metals A, B and C. He performs the following experiments:
i. Metal A is placed in a solution of the salt of B. No reaction occurs.
ii. Metal B is placed in a solution of the salt of C. A displacement reaction occurs.
iii. Metal C is placed in a solution of the salt of A. A displacement reaction occurs.
iv. Metal A is placed in a solution of the salt of C. No displacement reaction occurs.
i. Metal A is placed in a solution of the salt of B. No reaction occurs.
ii. Metal B is placed in a solution of the salt of C. A displacement reaction occurs.
iii. Metal C is placed in a solution of the salt of A. A displacement reaction occurs.
iv. Metal A is placed in a solution of the salt of C. No displacement reaction occurs.
i. Which metal is more reactive, B or C?
ii. Identify the type of reaction occurring in this process.
iii. Arrange A, B and C in decreasing order of reactivity.
iv. If B is zinc and A is copper, identify a possible metal C from the reactivity series.
