Answer: B
Explanation: its natural gas so its repleinishable
The weakest attractive force is london - dispersion forces
Explanation
- London- dispersion forces is aweak van der waal forces.
- London dispersion forces is the weakest intermolecular forces.
- Is a temporary attractive force when electron in two force that result when electron in two adjacent atoms occupy position that make the atoms form a temporary dipoles.
Answer : The mole fraction of NaCl in a mixture is, 0.360
Explanation : Given,
Moles of
= 7.21 mole
Moles of
= 9.37 mole
Moles of
= 3.42 mole
Now we have to calculate the mole fraction of
.
![\text{Mole fraction of }NaCl=\frac{\text{Moles of }NaCl}{\text{Moles of }NaCl+\text{Moles of }KCl+\text{Moles of }LiCl}](https://tex.z-dn.net/?f=%5Ctext%7BMole%20fraction%20of%20%7DNaCl%3D%5Cfrac%7B%5Ctext%7BMoles%20of%20%7DNaCl%7D%7B%5Ctext%7BMoles%20of%20%7DNaCl%2B%5Ctext%7BMoles%20of%20%7DKCl%2B%5Ctext%7BMoles%20of%20%7DLiCl%7D)
Now put all the given values in this formula, we get:
![\text{Mole fraction of }NaCl=\frac{7.21}{7.21+9.37+3.42}=0.360](https://tex.z-dn.net/?f=%5Ctext%7BMole%20fraction%20of%20%7DNaCl%3D%5Cfrac%7B7.21%7D%7B7.21%2B9.37%2B3.42%7D%3D0.360)
Therefore, the mole fraction of NaCl in a mixture is, 0.360
