Question

Which of the following is an appropriate answer with respect to rusting of iron ?
a) chemical formula of ruet is
$fe2o3.xh2o$
b) process of corrosion is enhanced by galvanisation
c) aluminium is more easily corroded than iron
d) both 'a' and 'c'
e) none of the above
​

Answer 1

Explanation:

Rust consists of hydrated iron(III) oxides Fe2O3·nH2O and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3). Given sufficient time, any iron mass, in the presence of water and oxygen, could eventually convert entirely to rust

Answer 2

Answer:

Answer is b) you process of corrosion is enhanced by galvanization
