Chromium is strange because it moves on to the 4s orbital instead of filling the 3d orbital with that last electron. Tricky.
Mark as brainliest if this helped! :)
Answer:
13.33 g/dm³
Explanation:
Concentration (g/dm³)= mass(g) ÷ volume (dm³)
Now you need to convert 150 cm³ to dm³
1000cm³ = 1 dm³
thus, 150 cm3= 150 ÷ 1000
= 15dm³
and you already have mass in grams
so concentration = 2 ÷ 0.15
= 13.33 g/dm³ and there you go.. solved ;)

Answer : The value of
at this temperature is 66.7
Explanation : Given,
Pressure of
at equilibrium = 0.348 atm
Pressure of
at equilibrium = 0.441 atm
Pressure of
at equilibrium = 10.24 atm
The balanced equilibrium reaction is,
![PCl_3(g)+Cl_2(g)\rightleftharpoons PCl_5(g)](https://tex.z-dn.net/?f=PCl_3%28g%29%2BCl_2%28g%29%5Crightleftharpoons%20PCl_5%28g%29)
The expression of equilibrium constant
for the reaction will be:
![K_p=\frac{(p_{PCl_5})}{(p_{PCl_3})(p_{Cl_2})}](https://tex.z-dn.net/?f=K_p%3D%5Cfrac%7B%28p_%7BPCl_5%7D%29%7D%7B%28p_%7BPCl_3%7D%29%28p_%7BCl_2%7D%29%7D)
Now put all the values in this expression, we get :
![K_p=\frac{(10.24)}{(0.348)(0.441)}](https://tex.z-dn.net/?f=K_p%3D%5Cfrac%7B%2810.24%29%7D%7B%280.348%29%280.441%29%7D)
![K_p=66.7](https://tex.z-dn.net/?f=K_p%3D66.7)
Therefore, the value of
at this temperature is 66.7
