i) 1 Iron objects react with water and oxygen to form hydrated iron oxide.
ii) Magnesium reacts with oxygen to form magnesium oxide.
iii) Carbon burns in a good supply of oxygen to form carbon dioxide.
iv) Carbon burns in a limited supply of oxygen to form carbon monoxide.
v) Hydrochloric acid reacts with magnesium to form magnesium chloride and hydrogen.

Answer 1

Answer:

1. Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur.
