is the ΔS°rxn for the formation of Cu₂O(s) from its elements.
WHAT IS ΔS°rxn FOR THE REACTION ?
The direction of spontaneous change is the direction in which total entropy increases. Total entropy change, also called the entropy change of the universe, is the sum of the entropy change of a system and of its surroundings
Standard entropy change of below reaction (ΔS°
)
∴ ΔH° = - 168.6 KJ/mol
Now, 
![= S^o_{Cu_2 O(s)} - [2 * S^o_{Cu(s)} + \frac{1}{2}(S^o_{O_2(g)}]](https://tex.z-dn.net/?f=%3D%20S%5Eo_%7BCu_2%20O%28s%29%7D%20-%20%5B2%20%2A%20S%5Eo_%7BCu%28s%29%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7D%28S%5Eo_%7BO_2%28g%29%7D%5D)
![= (93.1 J/molK)- [2 * 133.1 + \frac{1}{2}(205.0)]J/molK](https://tex.z-dn.net/?f=%3D%20%2893.1%20J%2FmolK%29-%20%5B2%20%2A%20133.1%20%2B%20%5Cfrac%7B1%7D%7B2%7D%28205.0%29%5DJ%2FmolK)
Thus, -75.6 J/mol K is the ΔS°rxn for the formation.

O = C = O Straight because there is no solitary electrons on C
The correct answer is d!!
Answer is: the ratio of amount NaOH reacting per unit amount FeCl₃ is 3 mol NaOH /1 mol FeCl₃.
Balanced chemical reaction:
3NaOH(aq) + FeCl₃(aq) → 3NaCl(aq) + Fe(OH)₃(s).
NaOH is sodium hydroxide.
FeCl₃ is iron(III) chloride.
Coefficient for sodium hydroxide is three and for iron(III hydroxide is one.
