(a)

Interpretation Introduction

Interpretation:

Whether carbon-13 is radioactive or stable has to be discussed.

Concept Introduction:

Isotopes are elements that have same atomic number but different mass number.

Radioisotopes are isotopes of an element having an unstable nucleus and dissipate energy in the form radiation in order to stabilize the nucleus.

(b)

Interpretation Introduction

Interpretation:

Presence of various isotopes in food has to discussed based on the analysis of hair sample.

Concept Introduction:

Isotopes are elements that have same atomic number but different mass number.

Radioisotopes are isotopes of an element having an unstable nucleus and dissipate energy in the form radiation in order to stabilize the nucleus.

The relative abundance of various isotopes is affected by some physical and biochemical processes, such processes are called isotope fractionation.

3. For the reactions below, draw the arrows corresponding to the transformations and draw in the boxes the reactants or products as indicated. Note: Part A should have arrows drawn going from the reactants to the middle structure and the arrows on the middle structure that would yield the final structure. For part B, you will need to draw in the reactant before being able to draw the arrows corresponding to product formation. A. B. Rearrangement ΘΗ
2. Draw the arrows required to make the following reactions occur. Please ensure your arrows point from exactly where you want to exactly where you want. If it is unclear from where arrows start or where they end, only partial credit will be given. Note: You may need to draw in lone pairs before drawing the arrows. A. B. H-Br 人 C Θ CI H Cl Θ + Br O
