Concept Introduction:
For a radioactive isotope, the relative instability is expressed in terms of half-life. Half-life is the time required for half of the given quantity of the radioisotope to undergo radioactive decay. Half-life of the radioactive isotope is independent of the quantity of the radioactive isotope. Half-life of a radioactive isotope can be expressed as,
Number of disintegrations per unit time is known as the activity of the sample. The rate of radioactive decay can be expressed as,
Where,
If initial activity of the sample is
Rearranging equation (3) as shown below,
Considering equation (2), the equation (3) can be rewritten in terms of fraction of radioactive atoms that is present after time

- A 0.552-g sample of an unknown acid was dissolved in water to a total volume of 20.0 mL. This sample was titrated with 0.1103 M KOH. The equivalence point occurred at 29.42 mL base added. The pH of the solution at 10.0 mL base added was 3.72. Determine the molar mass of the acid. Determine the Ka of the acid.arrow_forwardAs the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will its major product: 2,0° with a new C-C bond as If this reaction will work, draw the major organic product or products you would expect in the drawing aree below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and desh bonds if necessary, for example to distinguish between major products with different stereochemistry. If the major products of this reaction won't have a new C-C bond, just check the box under the drawing area and leave it blank.arrow_forwardwrite the mechanism of the nucleophilic acyl substitution reaction, please give an examplearrow_forward
