You would find the atomic weight of phosphorus and multiply that 2.3 and get 71.23.
Explanation:
Aluminium - Al
Iron Sulfate - FeSO4
The reaction is given as;
Al + FeSO₄ --> Al₂ (SO₄) ₃ + Fe
The balanced equation is given as;
2 Al + 3 FeSO₄ --> Al₂ (SO₄) ₃ + 3 Fe
In words it is given as;
Aluminium + Iron Sulfate --> Aluminium Sulfate + Iron

Answer:
Reaction is non-spontaneous when T > 738.5K and spontaneous when T < 738.5K
Explanation:
A reaction is non-spontaneous when ΔG° > 0 and is spontaneous when ΔG° < 0
ΔG° is defined as:
ΔG° = ΔH° - TΔS°
ΔG° will be > 0 (non-spontaneous) when ΔH° > TΔS° and vice versa. Thus:
-16100J > T × -21.8J/K
738.5K > T
That means the reaction is <em>non-spontaneous when T > 738.5K and spontaneous when T < 738.5K</em>
I hope it helps!
Only one dissolves lonic compounds often dissociate into ions solution, whereas covalently bonded molecules retain their molecule identity in solution.
