Answer:
Part A. The half-cell B is the cathode and the half-cell A is the anode
Part B. 0.017V
Explanation:
Part A
The electrons must go from the anode to the cathode. At the anode oxidation takes place, and at the cathode a reduction, so the flow of electrons must go from the less concentrated solution to the most one (at oxidation the concentration intends to increase, and at the reduction, the concentration intends to decrease).
So, the half-cell B is the cathode and the half-cell A is the anode.
Part B
By the Nersnt equation:
E°cell = E° - (0.0592/n)*log[anode]/[cathode]
Where n is the number of electrons being changed in the reaction, in this case, n = 2 (Sn goes from S⁺²). Because the half-reactions are the same, the reduction potential of the anode is equal to the cathode, and E° = 0 V.
E°cell = 0 - (0.0592/2)*log(0.23/0.87)
E°cell = 0.017V
Based on factors affecting solution formation;
- Strong solvent-solute intermolecular forces favors solution formation.
- Increase in entropy favours solution formation
- Decrease in enthalpy favours solution formation
<h3>What is a solution?</h3>
A solution is a substance formed when a substance known as solute dissolves in another substance know as solvent.
Factors that affect solution formation include:
- strength of intermolecular forces between solute and solvent
- entropy
- enthalpy
Strong solvent-solute intermolecular forces favors solution formation.
Increase in entropy favours solution formation
Decrease in enthalpy favours solution formation.

Answer:
1.1 mole
Explanation:
The mass of potassium chloride is 3.8 g . Look at the mole ratio you have between potassium chlorate and potassium chloride; what you will see is that every 2 moles of potassium chlorate will produce 2 moles of potassium chloride, i.e. you have a 1:1 mole ratio between the two compounds
deposition- gas to solid
