Number of half-lives that are elapsed has to be calculated from the given diagram where silicon-34 decays to phosphorus-34. Concept Introduction: Radioactive nuclides undergo disintegration by emission of radiation. All the radioactive nuclide do not undergo the decay at a same rate. Some decay rapidly and others decay very slowly. The nuclear stability can be quantitatively expressed by using the half-life. The time required for half quantity of the radioactive substance to undergo decay is known as half-life. It is represented as t 1 / 2 . The equation that relates amount of decayed radioactive material, amount of undecayed radioactive material and the time elapsed can be given as, ( Amount of radionuclide undecayed after n half lives ) = ( Original amount of radionuclide ) x ( 1 2 n )

Interpretation Introduction

Interpretation:

Number of half-lives that are elapsed has to be calculated from the given diagram where silicon-34 decays to phosphorus-34.

Concept Introduction:

Radioactive nuclides undergo disintegration by emission of radiation. All the radioactive nuclide do not undergo the decay at a same rate. Some decay rapidly and others decay very slowly. The nuclear stability can be quantitatively expressed by using the half-life.

The time required for half quantity of the radioactive substance to undergo decay is known as half-life. It is represented as t1/2.

The equation that relates amount of decayed radioactive material, amount of undecayed radioactive material and the time elapsed can be given as,

(Amount of radionuclideundecayed after n half lives) = (Original amount of radionuclide) x (12n)

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…
