Answer:
Osmosis.
Explanation:
If there is a selectively permeable membrane which is separating two liquids of different osmolarity or solute concentration then the process by which the solvent will move from one solution to another so as to attain equilibrium is known as osmosis. The existence of a selectively permeable membrane is the basic difference between diffusion and osmosis. Osmosis is characterized by the presence of such membrane which allows the movement of solvent only and restricts the movement of solute. In contrast to this, in diffusion there is no such restriction on the movement of particles from a region of high concentration to a region of low concentration.
In view of above in the given example, the solvent i.e. water will tend to move from pure water side towards the 4% NaCl solution side and the movement will continue until the osmolarity becomes equal on both the sides.
In the Bohr model- the electron was assumed to move in circular orbits. Wave mechanical model-the electron states are described by orbitals. Orbitals are nothing like Orbits.
The practical work inside the lab includes lab equipments, chemicals, and the practical outside a laboratory is more about conservation of nature and practicals include natural things in their living areas.
What are lab practicals?
Practicals are set up stations with lab equipments and chemicals and where students learn practical of the theoretical statements.
The exams of practicals are done to test the leaning of chemistry of the students.
Thus, the practical work inside the lab includes lab equipments, chemicals, and the practical outside a laboratory is more about conservation of nature and practicals include natural things in their living areas.

<span>The normal dividing line for soluble/not soluble is 0.1 M.
If a substance, as a saturated solution at room temp and pressure, cannot form a solution concentration of 0.1 M, then it is considered insoluble.
The 0.1 M figure was selected because _most_ substances are either well above that value or well below. Some substances (calcium hydroxide is one? not sure) come close to the 0.1 M dividing line but there are only a very few.</span><span>
but most likely it wont mix</span>
