A physical change is like freezing water and it turns into Ice.
They tend to form ionic bonds by losing electrons.
True final answer to this question

Answer:
Iron displaces copper ions
Explanation:
which means that iron in more reactive than copper.
(Fe2+) and cupric ion (Cu2 +) is converted into metallic copper. Fe (s) + Cu2 + (aq) —→ Fe2+ (aq) + Cu (s).
Since K3 is greater than 1, the reaction is thermodynamically favorable.
Data;
- FeF2 is in an acidic solution
- K2 > 1 is thermodynamically favorable
- k3 > 1 is not thermodynamically favorable
- K1<1 is not thermodynamically favorable
<h3>Hess Law</h3>
This states that the heat change in a given chemical reaction is the same irrespective of the number of process in which the reaction is effected.
Using Hess Law;

substituting this using Gibbs law,

Since K3 is greater than 1, the reaction is thermodynamically favorable.
