Ideal solutions obey Raoult's law, which states that:
P_i = x_i*(P_pure)_i
where
P_i is the partial pressure of component i above a solution
x_i is the mole fraction of component i in the solution
(P_pure)_i is the vapor pressure of pure component i
In this case,
P_benzene = 0.59 * 745 torr = 439.6 torr
P_toluene = (1-0.59) * 290 torr = 118.9 torr
The total vapor pressure above the solution is the sum of the vapor pressures of the individual components:
P_total = (439.6 + 118.9) torr = 558.5 torr
Assuming the gas phase also behaves ideally, the partial pressure of each gas in the vapor phase is proportional to its molar concentration, so the mole fraction of toluene in the vapor phase is:
118.9 torr/558.5 torr = 0.213
N2(g) + 3 H2(g) = 2NH3(g)
Qc = (NH3^2) / { (N2)(H)^3)}
Qc= 0.48^2 /{ ( 0.60) (0.760^3) }= 0.875
Qc < Kc therefore the equilibrium will shift to the right. This implies that Nh3 concentration will increase
Answer:
The final volume of the metal and water is 54.46mL
Explanation:
Hello,
To solve this question, we'll first of all find the volume of the metal and assuming there's no loss of water by overflow in the container, we'll add the volume of the metal to the volume of the water to get the final volume.
Data;
Mass of the metal = 45.5g
Volume of the water = 45mL
Density of the metal (ρ) = 3.65g/mL
Density of the metal = mass / volume
ρ = mass / volume
Volume (v) = mass / density
Volume = 45.5 / 3.65
Volume = 12.46mL
The volume of the metal is 12.46mL.
When the metal is added to the container 45mL of water, assuming no water was lost by overflow in the container, the final volume =
Final volume = volume of metal + volume of water
Final volume = 12.46 + 45.0
Final volume = 57.46mL
The final volume of the metal and water is 57.46mL
We are asked for the ratio of ions to produce neutral KCl. When neutral potassium chloride dissociates, the reaction is KCl = K+ + Cl-. Hence, the ratio of ions from the dissociation is 1 mole potassium ion per mole chlorine ion or 1 mole chlorine ion per potassium ion.
