Answer:
0.35 weight fraction is liquid Forsterite and 0.65 weight fraction is liquid Fayolite
Explanation:
The lever rule is typically used to calculate the weight fractions of phases in a binary equilibrium phase diagram. It is also used in the estimation of the fraction of solid and liquid phases for a specific binary composition and temperature condition existing between the solid and liquid lines. Therefore, using the Figure. 8.9 and the use of lever rule, the composition of the remaining liquid would be 0.35 weight fraction of liquid Forsterite and 0.65 weight fraction of liquid Fayolite.
5.20 mol C6H12* (84.2 g/mol C6H12)= 4.38*10^(2) g C6H12.
The answer should only have three significant figures, according to the numbers in the problem.
Hope this is helpful~
Answer:
Random motion in all directions.
Explanation:
It must be understood that the movement of atoms in a molecule is strictly based on the kinetic energy possessed by these particles.
Now, the gaseous state gives the highest level of freedom to these particles and thus they possess their highest kinetic energy in this state.
In gaseous helium, the atoms are expected to have a very high kinetic energy and thus they move in a haphazard or in an irregular manner.
This is principally due to the fact that in the gaseous state, atoms are most less confined and thus they are not restricted to a certain space.
This is in sharp contrast to the movement of atoms in the solid and liquid state. While atoms are mostly confined in the solid state such that they only merely vibrate about a fixed point, their movement in the liquid state is less restricted and they exhibit more freedom. This however is far less than the amount of freedom the gaseous state would avail its own particles.
They have strong intermolecular forces between their atoms, hence why more heat is necessary.
