Hello!
Since the cell remains its original size, it stands to reason that the concentration between the cell and the liquid is the same.
Answer:
<span>The concentration of water in the cell is the same as in the liquid, so water is moving in and out of the cell at the same rate</span>
The statement is false because the retention factor is affected by temperature, amount of material, or time.
Chromatography is a method of separation which involves the use of two phases; a stationary phase and a mobile phase.
The stationary phase is usually the adsorbent column while the mobile phase is the eluting solvent containing the mixture.
The retention factor is the ratio of the distance moved by the mixture to be separated to the distance moved by the solvent alone.
The retention factor depends on the degree of interaction between the mobile phase and the stationary phase. This interaction may be affected by temperature, amount of material, or time.
In summary, the retention factor, Rf, is affected by temperature, amount of material, or time because it depends on the interaction of the mobile phase and the stationary phase.

The molecular equation is
<span><span>AgNO3(aq]</span>+<span>HCl(aq]</span>→<span>AgCl(s]</span>+<span>HNO3(aq]</span></span>
How did I get this equation? Consider each reactant or product separately:
1 mole of <span>AgNO3</span> contains 1 mole of <span>Ag+</span> and 1 mole of <span>NO<span>−3</span></span> ions.
<span><span>Ag<span>+(aq]</span></span>+<span>NO<span>−3(aq]</span></span>+<span>H<span>+(aq]</span></span>+<span>Cl<span>−(aq]</span></span>→<span>AgCl(s]</span><span>⏐⏐↓</span>+<span>H<span>+(aq]</span></span>+<span>NO<span>−3(aq]</span></span></span>
