<u>Answer:</u> The equilibrium partial pressure of chlorine gas is 0.360 atm
<u>Explanation:</u>
For the given chemical equation:
![PCl_5(g)\rightleftharpoons PCl_3(g)+Cl2(g)](https://tex.z-dn.net/?f=PCl_5%28g%29%5Crightleftharpoons%20PCl_3%28g%29%2BCl2%28g%29)
The expression of
for above reaction follows:
![K_p=\frac{p_{Cl_2}\times p_{PCl_3}}{p_{PCl_5}}](https://tex.z-dn.net/?f=K_p%3D%5Cfrac%7Bp_%7BCl_2%7D%5Ctimes%20p_%7BPCl_3%7D%7D%7Bp_%7BPCl_5%7D%7D)
We are given:
![K_p=0.497\\p_{PCl_3}=0.651atm\\p_{PCl_5}=0.471atm](https://tex.z-dn.net/?f=K_p%3D0.497%5C%5Cp_%7BPCl_3%7D%3D0.651atm%5C%5Cp_%7BPCl_5%7D%3D0.471atm)
Putting values in above equation, we get:
![0.497=\frac{p_{Cl_2}\times 0.651}{0.471}\\\\p_{Cl_2}=0.360atm](https://tex.z-dn.net/?f=0.497%3D%5Cfrac%7Bp_%7BCl_2%7D%5Ctimes%200.651%7D%7B0.471%7D%5C%5C%5C%5Cp_%7BCl_2%7D%3D0.360atm)
Hence, the equilibrium partial pressure of chlorine gas is 0.360 atm
<span>The correct answer is that an ionic bond forms between charged particles. To form this bond, the particles transfer valence electrons (those in the outermost orbit). Specifically, in ionic bonding, the metal atom loses its electrons (thus becoming positive) and the nonmetal atom gains electrons (thus becoming negative).</span>
Based upon Max Planck's theory of black-body radiation, Einstein theorized that the energy in each quantum of light was equal to the frequency multiplied by a constant, later called Planck's constant. A photon above a threshold frequency has the required energy to eject a single electron, creating the observed effect.
I'd say the answer is D because they need to intake and keep as much water as possible.
