Answer 1

Explanation:

1. Iron is more reactive than gold . It can form compounds more easily and is hence placed above hydrogen in the reactivity series.It is mostly found in the form of iron oxide after reacting with oxygen and water . So , Gold is found in free state but iron is not.Jun 17, 2018
