Please Explain...???

Thank you for seeing and answering​

Answer 1

Answer:

Place the strips separately in the bottle of HCL. zinc will react more than iron. iron will be more reactive than copper. whereas copper will not displace hydrogen from the solution. zinc and iron will displace hydrogen from the solution.

Explanation:

based on the reactivity series zinc > iron >hydrogen>copper.

hence copper will not displace hydrogen from its acid.
