<u>Answer:</u>
<em>Adsorption is a phase conversion process that changes a mixture component from one state of matter to another is a </em><u><em>false statement.</em></u>
<em></em>
<u>Explanation:</u>
Adsorption is a process in which a solute accumulates on the surface of an adsorbent to form an atomic film.
The solute may be a gas or a liquid and the adsorbent will be a solid.
The resultant atomic film what we get is known as an adsorbate.
So molecules accumulate on the external or internal surface of the solids.
Whether or not such a reaction occurs can be determined by using the solubility rules for common ionic solids.

Answer:
1.014×10²³ atoms
Explanation:
Given data:
Volume of tungsten = 1.6 cm³
Density of tungsten = 19.35 g/cm³
Number of atoms of tungsten = ?
Solution:
First of all we will calculate the mass of tungsten.
density = mass/volume
by putting values,
19.35 g/cm³ = mass/1.6 cm³
Mass = 19.35 g/cm³× 1.6 cm³
Mass = 30.96 g
Number of moles of tungsten:
Number of moles = mass/molar mass
Number of moles = 30.96 g/ 183.84 g/mol
Number of moles = 0.1684 mol
1 mole contain 6.022×10²³ atoms.
0.1684 mol × 6.022×10²³ atoms / 1mol
1.014×10²³ atoms
