![P_T=112.4torr](https://tex.z-dn.net/?f=P_T%3D112.4torr)
Explanation:
Hello there!
In this case, since these problems about gas mixtures are based off Dalton's law in terms of mole fraction, partial pressure and total pressure, we can write the following for hydrogen, we are given its partial pressure:
![P_{H_2}=x_{H_2}*P_T](https://tex.z-dn.net/?f=P_%7BH_2%7D%3Dx_%7BH_2%7D%2AP_T)
And can be solved for the total pressure as follows:
![P_T=\frac{P_{H_2}}{x_{H_2}}](https://tex.z-dn.net/?f=P_T%3D%5Cfrac%7BP_%7BH_2%7D%7D%7Bx_%7BH_2%7D%7D)
However, we first calculate the mole fraction of hydrogen by subtracting that of nitrogen to 1 due to:
![x_{H_2}+x_{N_2}=1\\\\x_{H_2}=1-0.333=0.667](https://tex.z-dn.net/?f=x_%7BH_2%7D%2Bx_%7BN_2%7D%3D1%5C%5C%5C%5Cx_%7BH_2%7D%3D1-0.333%3D0.667)
Then, we can plug in to obtain the total pressure:
![P_T=\frac{75.0torr}{0.667}\\\\P_T=112.4torr](https://tex.z-dn.net/?f=P_T%3D%5Cfrac%7B75.0torr%7D%7B0.667%7D%5C%5C%5C%5CP_T%3D112.4torr)

Answer:
Ksp = 0.1762
Explanation:
Applying
a) moles of HCl added, n= CV=0.5×0.012 = 6×10-3mol
b) since 0.006mol is present in 0.012dm3 of HCl
It implies moles of borax
C) Concentration = 0.706M
Ksp = [0.5]^2[0.706]= 0.176
Answer:
B
Explanation:
The average kinetic energy of the Substance changes.
Aromatic compound has continuous cyclic structure with( 4n+2)π electrons (Huckels rule), where n = 0,1,2…
Here number of pi electron are 6, where 4 from two double bond and 2 from nitrogen non-bonding electrons, hence it has total 6 pi electrons, therefore
6= ( 4n+2)π
4 = 4n
n =1
Hence it is an aromatic compound
