Answer:
The liquid molecules stay towards the bottom but one or two do make it all the way to the top. The molecules in the gas are also moving faster than the molecules in the liquid phase.
Answer:
It would be true cause the example of gas would be coke soda

Explanation:
We're asked to find the molar concentration (molarity) of the HCl solution, given some titration measurements.
Let's first write the chemical equation for this neutralization reaction:
NaOH(aq)+HCl(aq)→NaCl(aq)+H2O(l)
Since we're given the molarity and volume of the NaOH solution used, we can calculate the moles be using the molarity equation:
mol solute=(molarity)(L soln)
=(0.1molL)(0.0332L)=0.00332 mol NaOH
Since all the coefficients in the chemical equation are 1, the relative number of moles of HCl used is also 0.00332 mol.
Finally, let's use the molarity equation again to find the molarity of the HCl solution (given the volume of NaOH soln is 40 mL, which must be in liters when using molarity equations):
molarity=mol soluteL soln
=0.00332lmol HCl0.040lL=0.083M
