Question

A student was given Manganese, Zinc, Iron and Copper metals. Identify
1) Will not displace hydrogen from dilute hydrochloric acid
ii) Will react only with steam to give hydrogen gas​

Answer 1

Answer:

Ye the answer will copper it does not desplace.

Answer 2

1) Copper (Cu) will not displace hydrogen from dilute Hydrochloric acid.

- This due to the fact that copper lies below hydrogen gas in the reactivity series, i.e., it is less reactive than hydrogen gas.

- So it will not displace hydrogen from acids.

2) Zinc and Iron reacts with steam to give hydrogen gas​.

- These metals do not react with cold/warm water, and can only react with steam.
