2.35 describe how the rusting of iron may be prevented by grease, oil, paint, plastic and galvanising

Grease, oil, paint and plastic prevent air and/or water from coming into contact with iron. This means the reaction that rusts iron can't occur.

Galvanising is coating in zinc. This Zinc react in the air to form ZnCO3 which prevents air and/or water from coming into contact with the iron.

    When the zinc corrodes it loses the electrons these electrons then flow into the iron atons which have lost electrons when they've corroded meaning they don't form ions of the don't form ions then it can't rust
