Answer:
kp= 3.1 x 10^(-2)
Explanation:
To solve this problem we have to write down the reaction and use the ICE table for pressures:
2SO2 + O2 ⇄ 2SO3
Initial 3.4 atm 1.3 atm 0 atm
Change -2x - x + 2x
Equilibrium 3.4 - 2x 1.3 -x 0.52 atm
In order to know the x value:
2x = 0.52
x=(0.52)/2= 0.26
2SO2 + O2 ⇄ 2SO3
Equilibrium 3.4 - 0.52 1.3 - 0.26 0.52 atm
Equilibrium 2.88 atm 1.04 atm 0.52 atm
with the partial pressure in the equilibrium, we can obtain Kp.
![Kp=\frac{PSO3^2}{PSO2^2 PO2}=\frac{(0.52)^2}{(2.88)^2(1.04)}=0.03135](https://tex.z-dn.net/?f=Kp%3D%5Cfrac%7BPSO3%5E2%7D%7BPSO2%5E2%20PO2%7D%3D%5Cfrac%7B%280.52%29%5E2%7D%7B%282.88%29%5E2%281.04%29%7D%3D0.03135)
Answer:
melting, freezing, sublimation, deposition, condensation, and vaporization. These changes

hope it helps...i dont know if its right but i hope it helps
The ideal gas law:
![pV=nRT \Rightarrow p=\frac{nRT}{V}](https://tex.z-dn.net/?f=pV%3DnRT%20%5CRightarrow%20p%3D%5Cfrac%7BnRT%7D%7BV%7D)
p - pressure, n - number of moles, R - the gas constant, T - temperature, V - volume
The volume and temperature of all three containers are the same, so the pressure depends on the number of moles. The greater the number of moles, the higher the pressure.
The mass of gases is 50 g.
![Ar \\ M \approx 39.948 \ \frac{g}{mol} \\ n=\frac{50 \ g}{39.948 \ \frac{g}{mol}} \approx 1.25 \ mol \\ \\ SF_6 \\ M \approx 146.06 \ \frac{g}{mol} \\ n=\frac{50 \ g}{146.06 \ \frac{g}{mol}} \approx 0.34 \ mol \\ \\ Cl_2 \\ M=70.9 \ \frac{g}{mol} \\ n=\frac{50 \ g}{70.9 \ \frac{g}{mol}} \approx 0.71 \ mol](https://tex.z-dn.net/?f=Ar%20%5C%5C%0AM%20%5Capprox%2039.948%20%5C%20%5Cfrac%7Bg%7D%7Bmol%7D%20%5C%5C%0An%3D%5Cfrac%7B50%20%5C%20g%7D%7B39.948%20%5C%20%5Cfrac%7Bg%7D%7Bmol%7D%7D%20%5Capprox%20%201.25%20%5C%20mol%20%5C%5C%20%5C%5C%0ASF_6%20%5C%5C%0AM%20%5Capprox%20146.06%20%5C%20%5Cfrac%7Bg%7D%7Bmol%7D%20%5C%5C%0An%3D%5Cfrac%7B50%20%5C%20g%7D%7B146.06%20%5C%20%5Cfrac%7Bg%7D%7Bmol%7D%7D%20%5Capprox%200.34%20%5C%20mol%20%5C%5C%20%5C%5C%0ACl_2%20%5C%5C%0AM%3D70.9%20%5C%20%5Cfrac%7Bg%7D%7Bmol%7D%20%5C%5C%0An%3D%5Cfrac%7B50%20%5C%20g%7D%7B70.9%20%5C%20%5Cfrac%7Bg%7D%7Bmol%7D%7D%20%5Capprox%200.71%20%5C%20mol)
The greatest number of moles is in the container with Ar, so there is the highest pressure.
Alkali metals.
Elements found in group 1 of the periodic table.
Answer:
ionic bonding occurs between ions and covalent bonding occurs when atoms have electrons in common (they share).
