The solute, while moving in the column is always in equilibrium with both the stationary phase and the mobile phase.

Correct Answer: True
The solute, while moving in the column is always in equilibrium with both the stationary phase and the mobile phase. But, the two phases will never be in equilibrium with each other.

How is the molar concentration of solute in stationary phase related to molar concentration of solute in the mobile phase?

Which of the following is defined as the ratio of moles of solute in stationary phase to the moles of solute in the mobile phase?

The chromatography in which the sample is forced through a column of the stationary phase by pumping a liquid (mobile phase) at high pressure through the column is referred to as ___________

In a liquid-liquid extraction, 10 kg of a solution containing 2 kg of solute C and 8 kg of solvent A is brought into contact with 10 kg of solvent B. Solvent A and B are completely immiscible in each other whereas solute C is soluble in both the solvents. The extraction process attains equilibrium. The equilibrium relationship between the two phases is Y* = 0.9X, where Y* is the kg of C/kg of B and X is kg of C/kg of A. Choose the correct answer.

A mobile was dropped from a balcony if the mass of the mobile phone is 0.5kg and the mobile phone was dropped from a height of 100m, g = 10m/s2. So what is the potential energy of mobile phone?

In Column chromatography, the stationary phase is made of _________ and the mobile phase is made of _________

Arrange the following demographic transition theory given by Blackur (ascending order)
1. Declining phase with low mortality, lower fertility
2. Low stationary phases with low fertility and low mortality
3. Early expanding phase marked by high fertility
4. High stationary phase marked by high fertility and mortality

Estimate the interfacial solute concentration in the two liquids when the solute concentration is 45000 kg-moles/m3, interfacial solute concentration in liquid is 40000 kg-moles/m3, diffusivity is 2.5 × 10-11 m2/s and the length of the tube is 5m3 and the partition coefficient is 0.25.

The stock of stationary on 1st January 2002 is Rs. 300, payment for stationary during the year is 2002 Rs. 1,080 and stock of stationary on 31st December 2002 is Rs. 50. What will be the amount shown in income and expenditure account for the year ending 31st December, 2002?

Andrew bought a new mobile phone from the market. While studying its specifications, he realizes that the mobile phone fails to comply with the national standards. Which dimension of ‘product quality’ has the mobile phone failed in?
