Question
Chapter 5, Problem 5.49UTC
Interpretation Introduction
Interpretation:
To draw the protons and the neutrons after a positron emission.
Concept introduction:
A proton is turned into a neutron and a positron (with a positive charge) leaves the nucleus.
Positron emission happens when a nucleus emits a positron
Expert Solution & Answer
Answer to Problem 5.49UTC
Solution:
Explanation of Solution
Positron emission happens when a nucleus emits a positron
. A proton is turned into a neutron and a positron (with a positive charge) leaves the nucleus. In the following figure, orange spheres represent the protons and grey spheres represent the electrons:
At the beginning there are 6 protons and 5 neutrons, after the emission there are 5 protons and 6 neutrons.
Conclusion
Thus, positron emission happens when a nucleus emits a positron

b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not
themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting
four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation
you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be
both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the
four structures.

How to measure distance and calculate rate
For the titration of a divalent metal ion (M2+) with EDTA, the stoichiometry of the reaction is typically:
1:1 (one mole of EDTA per mole of metal ion)
2:1 (two moles of EDTA per mole of metal ion)
1:2 (one mole of EDTA per two moles of metal ion)
None of the above
