is directly related to the ideal gas law.
The ideal gas law states that:
. Rewriting this gives:
. R is the universal gas constant, so its value is fixed. For a given sample, n is the number of moles of the gas, so its value would be fixed too. This means that the value of
would be a fixed constant as well. Therefore, whatever the initial value
is, it should be equal to the final value

Explanation:
Answer: The molar solubility of barium fluoride is 0.0183 moles/liter.
Explanation:
The equation for the reaction will be as follows:
By Stoichiometry,
1 mole of 
gives 2 moles of 
and 1 mole of 
Thus if solubility of is s moles/liter, solubility of is s moles/liter and solubility of is 2s moles/liter
Therefore,
![K_sp=[Ba^{2+}][F^{-}]^2](https://tex.z-dn.net/?f=K_sp%3D%5BBa%5E%7B2%2B%7D%5D%5BF%5E%7B-%7D%5D%5E2)
![2.45\times 10^{-5}=[s][2s]^2](https://tex.z-dn.net/?f=2.45%5Ctimes%2010%5E%7B-5%7D%3D%5Bs%5D%5B2s%5D%5E2)
Thus the molar solubility of barium fluoride is 0.0183 moles/liter.
Answer:
Acid solutions will be those which lights up a bulb when a circuit is connected through them.
Explanation:
Acid solutions such as HCl and HNO3 are polar in nature and permits the flow of electricity through them. Whereas non-polar solutions like ethanol and glucose solution will not allow the flow of electricity through them.
Therefore, when an electric circuit is completed by dipping the nails connected to a battery and a bulb into the different solutions, the lighting up of the bulb indicates which solutions are acids.
