Answer: By shifting the equilibrium to align with the interest of the company.
Explanation: Major production companies depend on the principle of chemical equilibrium to normalize their production depending on their interests. This principle is called Le Chatelier's principle.
The major concern of Chemical industries is their output and production time. Knowledge of Chemical equilibrium can help to maximize the output in a relatively less time by considering some factors.
Factors such as Temperature, Pressure, Concentration, and Catalyst presence can change the chemical equilibrium to benefit companies.
I have included the work and the process which is easiest for me to balance chemical equations. I hope it helps!
Answer:
a. Xm = 0.0229
b. 0.0234 moles
c. 354.1 g/mol
Explanation:
ΔP = P° . Xm
ΔP = P° - P', where P° is vapor pressure of pure solvent and P', vapor pressure of solution-
This is the formula for lowering vapor pressure.
If we apply the data given: 523 Torr - 511 Torr = 523 . Xm
Xm = ( 523 Torr - 511 Torr) / 523 Torr → 0.0229
Xm = Mole fraction of solute → Moles of solute / Total moles (sv + solute)
We can make this equation to determine moles of solute
0.0229 = Moles of solute / Moles of solute + 1
0.0229 (Moles of solute + 1) = Moles of solute
0.0229 = Moles of solute - 0.0229 moles of solute
0.0229 = 0.9771 moles of solute → 0.0229 / 0.9971 = 0.0234 moles
Molecular mass of solute → g/mol → 8.3 g / 0.0234 mol = 354.1 g/mol
The hydrogen ion concentration is calculated as follows
Ph + POh =14
ph= 14-9.85= 4.15
anti -H+
=anti (-4.15) = 7.07 x10^-5 moles per liter
Isn't it a because in b at the start of the equation the E in Fe just disappeared
