The water in Glass A is cooler than the water in Glass B; therefore, the particles in Glass A move slower.
Option D
<h3>Chemical Reactions</h3>
Generally,the experiment shows that glass B temperature is higher than glass temperature A and this is given that observation that the solute dissolves faster in glass B than glass A.
Therefore,The water in Glass A is cooler than the water in Glass B; therefore, the particles in Glass A move slower.

We need to know how many valence electrons are present in a given molecule in order to determine its Lewis dot structure.
<h3>
What is Lewis dot structure?</h3>
Lewis dot structure is defined as the visual representation of atoms' electrons using a diagram. It describe the bonds that exist between a molecule's lone pairs of electrons and its atoms.
A lone pair of electrons on the atom with the formal charge of 1- can typically be converted into a bonding pair that is shared with the atom that has the formal charge of 1+ in order to reduce the formal charges when they are present.
Thus, we need to know how many valence electrons are present in a given molecule in order to determine its Lewis dot structure.

Rf values may vary. Rf values vary depending on the material and solvent. The solvent that is used will alter the Rf value.
Rf values are typically higher for low polarity chemicals compared to higher polarity ones. Generally speaking, as polarity of a compound increases, so does its adsorptivity (i.e. the more polar the compound then the stronger it binds to the adsorbent). Solvents get more eluting as they become more polar.
The greater the compound's polarity, the more readily it will bind to the adsorbent, the closer it will come to the baseline, and the lower its Rf value. Many scientists use normal-phase flash chromatography with dichloromethane and methanol as the mobile phase to purify polar organic molecules. Due to methanol's high polarity and protic chemistry, it can frequently be difficult to optimize this solvent system.
