The phase in which the molecules move fastest is in water vapor or as a form of a gas.
Answer:
Particle arrangement of solids: close tightly packing.
Particle arrangement of liquids: close together with no regulations and more vibration movements than in solids.
Movement of particle in gases is freely and very fast, independent from other particles.
Forces between particles in liquids are attractive forces, but not as strong as in solid state, because they have greater energy of movement and vibration then the particle in solid state.
There are no forces between particles in gaseous state, except if they are close enough, then they repel each other.
We can't compress particle in solid and liquid state, but we could in gaseous state.
Shape and volume of group of particle in gaseous state are definite.
Gas has indefinite shape and volume.

pH value of a 0. 011 m naf solution is 8.57.
Solution
This problem uses the relationship between Kb and the dissociation constants which is expressed as Kw = KaKb. Calculations are as follows:
Kb = KaKb
1.00 x 10^-14 = 7.2 x 10^-4(x)
x = 1.39 x 10^-11
We now need to calculate the [OH¯] using the Kb expression:
1.39 x 10^-11 = x^2 / (0.30 - x)
The denominator can be neglected. Thus, x is 3.73 x 10^-6.
pOH = -log 3.73 x 10^-6 = 5.43
pH = 14-5.43 = 8.57
