The correct answer is option B.
The liquid or gas that carries the sample across the solid support is called mobile phase.
In chromatography, there are two phases: mobile phase and solid phase.
The mobile phase can be either in gas form or liquid form.
While performing the chromatography technique, mobile phase moves over the stationary phase and its components adsorb to the stationary phase and set apart from each other at different rates.
In general, mobile phase refers to the solvent phase that slides over the stationary phase through the chromatography paper.
on the other hand, stationary phase is motionless.

Answer:
6.460 gm is the correct answer .
Explanation:
Given
Kate’s blood volume=
blood glucose=
As we know that

The
includes the blood glucose of the 
So
of the Kate’s blood volume can be determined by



To convert into the gm we have divided by the 1000

Therefore the glucose in her blood=

The mole is simply an Avogadros number of anything( in this case Br atoms)
The Avogadro number is 6.022 x 10^23.
So no of moles = No of atoms / 6.022 x 10^23 = 2.03 x 10^24 / 6.022 x 10^23 = 3.37 Moles.
Answer: H2O
Explanation: The given balanced chemical reaction is,
This reaction is a reversible reaction.
The rate of forward reaction will be,
The rate of backward reaction will be,
And at equilibrium the rate of reaction is equal to the rate of backward reaction divided by the rate of forward reaction.
