Answer:
Explanation:
The Chemical equation for the formation of rust is:
Iron + Water + Oxygen ----> Rust
4 Fe(s) + 6 H2O(l) + 3 O2(g) → 4 Fe(OH)3(s)
The Iron Hydroxide However dehydrates to produce Fe2O3 * nH2O

There are two kinds of mixtures
a) homogeneous : the boundary of the two components is not physically distinct
b) heterogeneous:the boundary of the two components is physically distinct
the following separation techniques are common for mixtures
1) filtration: if the two components are forming heterogeneous mixture we can separate them by filtration.
2) boiling: if boiling point of one of the components is less than other
3) magnetic separation: if one of the component is magnetic
4)sieve method: for solid components with difference in size of particles
5) hand picking
Thus the correct match will be as shown in the figure
