Solution
The process of depositing a thin layer of zinc on iron articles is called galvanisation.
Explanation:
The galvanisation process involves dipping clean iron or steel articles into molten zinc to create a protective barrier coating. The zinc layer prevents rust by shielding the underlying iron from oxygen and moisture in the environment. Even if the zinc coating is scratched, it will corrode first to sacrificially protect the iron.

No chemical reaction takes place when granules of a rusty-brown solid A are mixed with the powder of another solid B. However, when the mixture is heated, a reaction takes place between its components. One of the products C is a metal and settles down in the molten state while the other product D floats over it. It was observed that the reaction is highly exothermic.
