From the calculation, the partial pressure of Cl2 is 1.98 atm. Option B
<h3>What is the equilibrium constant?</h3>
The term equilibrium constant refers to the value that shows us the extent to which reactants are converted into products. We know that the equilibrium constant can only be obtained by the use of the equilibrium partial pressures of each of the species.
Thus we have;
K = p PCl3 . pCl2/pPCl5
p PCl3 = partial pressure of PCl3
pCl2 = partial pressure of Cl2
pPCl5 = partial pressure of PCl5
K = equilibrium constant
Substituting values;
1.05 = 0.463 * pCl2/0.875
pCl2 = 1.05 * 0.875/0.463
pCl2 = 1.98 atm

Answer:
the correct option is B
Explanation:
The correct option is b, since if we reach pH 7, it means that the acid-base reaction is neutralized, therefore the base has been neutralized by an acid or vice versa, without taking into account the proteins or the amounts of both components .
The volume of 0.555M KNO3 solution would contain 12.5 g of solute iss 223 mL.
<h3>What is the relationship between mass of solute and concentration of solution?</h3>
The mass of solute in a given volume of solution is related by the formula below:
- Molarity = mass/(molar mass * volume)
Therefore, volume of solution is given by:
Volume = Mass /molarity * molar mass
Molar mass of KNO₃ = 101 g/mol
Volume = 12.5/(0.555 * 101)
Volume = 0.223 L or 223 mL
In conclusion, the volume of the solution is obtained from the molarity of solution as well as mass and molar mass of solute.
