Answer:
it means compound A is <u>less</u> polar than compound B
Explanation:
It is sure that the more polar the solvent, the faster compounds elute, regardless of the compounds polarity. This means changing the solvent polarity cannot change the order compounds elute from a TLC or column. This may seem non intuitive, as it would seem that a polar solvent would move a polar compound farther than a nonpolar compound.
The object that shows fast motion is said to have a higher speed while the one with slow motion is said to have a slow speed.

Answer:
The water falls to the earth as precipitation, such as rain, hail, sleet, and snow. When precipitation reaches the earth's surface, some of it will flow along the surface of the land and enter surface water like lakes, streams, and rivers, as runoff. The rest of it soaks or percolates into the soil, called
The frequency of a 4,600 cm wave is 652 Hz
Frequency is the number of waves that pass a fixed point in unit time
Here given data is
Wave = 4,600 cm = 4.6 × 10⁸ nm
We have to calculated frequency = ?
Frequency =v = c/λ
Frequency = 3×10⁸m / 4.6 × 10⁸ nm
Frequency = 652 Hz

Answer:
Explanation:
In ionic bonding, atoms transfer electrons to each other. Ionic bonds require at least one electron donor and one electron acceptor. In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons.
