Answer:- 
for the reaction is -58 kJ/mol.
Solution:- Oxidation half reaction taking place at the anode is--
= 0.14 V
Reduction half equation taking place at the cathode is---
= -0.04V
for the cell = 
for the cell = -0.04V + 0.14V = 0.10V
Now we could easily calculate by using the below formula--
= -nF
where n is the number of electrons transferred in the over all reaction. Looking at two half equations the value of n is 6.
F is Farady constant and it's value is 96500 C/mol.
Plugging in the values in the formula...
= -(6)(96500)(0.10)
= -57900 J
Since, 1000 J = 1 kJ
So, = -58 kJ/mol
500 J (I've had the same question before so I know what answers there are... lol)
<h3>Answer:</h3>
When a solute is added to a solution, it remains homogeneous because the solute is soluble in given solvent.
<h3>Explanation:</h3>
Homogeneous mixtures, also called true solutions are those mixtures in which the components proportions are same throughout in any given sample. For example, the mixture of table salt (NaCl) and water. When the solution is unsaturated and further NaCl is added to it, it will dissolve the NaCl because the saturation point is still not reached. Remember, as "<em>Like Dissolves Like</em>" NaCl being polar in nature will interact with water molecules and will dissociate into Na⁺ and Cl⁻ ions surrounded by δ- O and δ+ H atoms of water molecules.
<h3>Conclusion:</h3>
In order to form a Homogeneous mixture the solution must be unsaturated, solvent must have affinity for incoming solute particles and the size of solute should be equal to 1 Â (Angstrom).
