Answer 1

Explanation:

Food cans are coated with tin and not with zinc because zinc is above the tin in reactivity series means more reactive than tin and can react with food elements preserved in it.

This is because zinc is above the tin in reactivity series which means that it is more reactive than tin and can react with food preserved in it and can poison it.

so that's why food items are coated with tin not with zinc.
