Chapter 20, Problem 96RQ
Interpretation Introduction

Interpretation:

The activity of the sample Technetium-99m (gamma emitter, t12=6.02 hr) at the end of the day, that is, after 8 hours is to be calculated given that it had an activity of 4.52×106Ci in early morning.

Concept Information:

Technetium-99m is the isotope of technetium that is a useful medical radioisotope. It is used as a radioactive tracer and also acts as gamma cameras. Its mass number is 99 and therefore it’s nucleus will last longer as it is in excited state.

The exponential form of the relation between concentration and time for a first-order reaction is as follows,

[A]=[A]0ekt

The half-life of a first-order reaction is given as,

t1/2=ln2k=0.693k

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ? Will the first MgBr product that forms in this reaction create a new CC bond? olo ? OH جمله O Yes Ⓒ No MgCl ? Will the first product that forms in this reaction create a new CC bond?
