O Hydrated Ferric oxide
ОО
Calcium sulphate
O
Calcium carbonate​

Answer 1

Answer:

Hydrated Ferric oxide

Explanation:

The formation of rust requires iron, water and oxygen. Although it's a complex process, it's chemical equation is simply written as :                                                                                            

                                                                                                                                                                                                                                                4Fe + 3O 2 + 6H 2O → 4Fe(OH) 3

And 4Fe(OH)2 is called Hydrated Ferric Oxide.
