Answer:
HYDROGEN BONDING (determines rate of migration)
Explanation:
There are two forces acting on the sample:
<u>Gravity/ Capillary action force:</u> This can include gravity, pumping of fluid through the tube, or the capillary action of the liquid when moving up the sheet of paper.
<u>Interactive force with the gel used:</u> The another force is dependent on the fundamental properties of individual components with fluid. These can be polarity, charge, adhesive nature, etc.
The most type of the chromatography is exploiting polarity of the molecules. So in TLC, we have a sheet coated with silica gel usually (polar), and a liquid that contains a mixture of different compounds which is being pushed up paper through the capillary action.
Some liquid's polarity will be greater than the others, and that's why the liquids move at various speeds based on favorable/ unfavorable interactions between different compounds in the mixture.
In this way, one can separate a mixture into individual constituting parts.
<u>Thus, the relative amount of hydrogen bonding to the stationary phase will determine the Relative Rate of Migration of the various components in the sample.</u>
Answer:
Both are different.
Explanation:
Both rocks are different from one another because both formed from different types of rocks. Rock A was formed from small pieces of rock while on the other hand, Rock B was formed from liquid rock so they both have different sources of rocks from which they were formed. Forming at the same time does not show that they are similar to each other, it is their source which decides that they are similar or different.

Answer:
14.336 g MnF₂
Explanation:
number of moles = mass / molecular weight
number of moles of MnI₂ = 55 / 309 = 0.178 moles
number of moles of F₂ = 55 / 38 = 1.447 moles
From the reaction and the number of moles calculated we deduce that the fluorine F₂ is a limiting reactant.
So:
if 13 moles of F₂ reacts to produce 2 moles of MnF₃
then 1.447 moles of F₂ reacts to produce X moles of MnF₃
X = (1.447 × 2) / 13 = 0.223 moles of MnF₃ (100% yield)
For 57.2% yield we have:
number of moles of MnF₃ = (57.2 / 100) × 0.223 = 0.128 moles
mass = number of moles × molecular weight
mass of MnF₃ = 0.128 × 112 = 14.336 g
