Answer:
It converts The liquid into a gas at the same temperature.
Explanation:
The process is know as diffusion in which substances move from higher concentration to lower concentration
Explanation:
<u>Moles is denoted by given mass divided by the molecular mass , </u>
Hence ,
n = w / m
n = moles ,
w = given mass ,
m = molecular mass .
For example ,
For a compound X ,
The given mass i.e. w = 20 g
and the molecular mass ,i.e. , m = 10 g / mol
Then the moles can easily be calculated by using the above formula ,
n = w / m
n = 20 g / 10 g/mol = 2 mol
Hence , answer = 2 mol.
C.
Water is polar because one side of the molecule is positive and the other is negative.
I believe that #1 is the lie, but I'm not great at this subject.
