Answer
B Thomson
DC States
A Fischer
C Pauling​

Answer 1

Answer:

idk

Explanation:

After extraction, lanthanides could be stripped very easily from the ionic liquid phase with dilute nitric acid. From the temperature dependence data, the thermodynamic parameter values (ΔH, ΔS and ΔG) were calculated

Answer 2

The correct answer is Nishihama et al.

Explanation:

• The separation of lanthanides by solvent extraction was reported by Nishihama et al.
• All the lanthanides look like silvery-white soft metals and in presence of air tarnish rapidly. The separation of lanthanides from other elements forms lanthanide compounds which are chemically combined with specific substances. one of the best processes which is used to separate lanthanides is the ion-exchange method.
• Methods used for the separation of lanthanides are:

(1) ion-exchange method

(2) Solvent extraction method

(3) Paper chromatography

(4) Gas chromatography

(5) thin-layer chromatography

(6) Complex formation
