(a)
Interpretation:
Whether radioactivity is expected to be in the solution or not is to be determined.
Concept introduction:
The solution is a homogeneous mixture of two or more substances. It can exist in any of the phases. Saltwater, rubbing alcohol, bleach, and air are some examples of solutions. It has two components: solute and solvent. The solute is the substance that is present in smaller quantity and gets itself dissolved in the other substance. The solvent is the substance that is present in a larger amount and it dissolves solute in itself.
The saturated solution is the solution that contains the maximum amount of solute dissolved in the solvent. Any additional amount of solute will not get dissolved in it. Soda is an example of a saturated solution.
(b)
Interpretation:
Whether radioactivity is present in all the solid or just in the seed crystal is to be determined.
Concept introduction:
Radioactivity is the property of matter due to which it emits energy and subatomic particles simultaneously. The emissions of the most common forms of spontaneous radioactive decay are an alpha particle, beta particle, and gamma-ray and neutrino.

- You have now performed a liquid-liquid extraction protocol in Experiment 4. In doing so, you manipulated and exploited the acid-base chemistry of one or more of the compounds in your mixture to facilitate their separation into different phases. The key to understanding how liquid- liquid extractions work is by knowing which layer a compound is in, and in what protonation state. The following liquid-liquid extraction is different from the one you performed in Experiment 4, but it uses the same type of logic. Your task is to show how to separate apart Compound A and Compound B. . Complete the following flowchart of a liquid-liquid extraction. Handwritten work is encouraged. • Draw by hand (neatly) only the appropriate organic compound(s) in the boxes. . Specify the reagent(s)/chemicals (name is fine) and concentration as required in Boxes 4 and 5. • Box 7a requires the solvent (name is fine). • Box 7b requires one inorganic compound. • You can neatly complete this assignment by hand and…arrow_forwardb) Elucidate compound D w) mt at 170 nd shows c-1 stretch at 550cm;' The compound has the ff electronic transitions: 0%o* and no a* 1H NMR Spectrum (CDCl3, 400 MHz) 3.5 3.0 2.5 2.0 1.5 1.0 0.5 ppm 13C{H} NMR Spectrum (CDCl3, 100 MHz) Solvent 80 70 60 50 40 30 20 10 0 ppm ppm ¹H-13C me-HSQC Spectrum ppm (CDCl3, 400 MHz) 5 ¹H-¹H COSY Spectrum (CDCl3, 400 MHz) 0.5 10 3.5 3.0 2.5 2.0 1.5 1.0 10 15 20 20 25 30 30 -35 -1.0 1.5 -2.0 -2.5 3.0 -3.5 0.5 ppm 3.5 3.0 2.5 2.0 1.5 1.0 0.5 ppmarrow_forwardShow work with explanation. don't give Ai generated solutionarrow_forward
