The complete balanced equation for bombardment of C 249 f by O 18 to form S 263 g needs to be determined. Concept Introduction : Radioactive nucleus undergoes decay as the ratio of number of protons to number of neutrons is not equal. It will dissociate to smaller fragments releasing alpha, beta or gamma particles. If the ratio of number of protons to number of neutrons is less or equal to 1, then positron is released and if the ratio is more than 1 then beta particle is released.

Answer 1

Question

Chapter 20, Problem 15E

(a)

Interpretation Introduction

Interpretation:

The complete balanced equation for bombardment of C249f by O18 to form S263g needs to be determined.

Concept Introduction:

Radioactive nucleus undergoes decay as the ratio of number of protons to number of neutrons is not equal. It will dissociate to smaller fragments releasing alpha, beta or gamma particles. If the ratio of number of protons to number of neutrons is less or equal to 1, then positron is released and if the ratio is more than 1 then beta particle is released.

(b)

Interpretation Introduction

The other product formed by the alpha decay of S263g needs to be determined wherein there is alpha particle emitted.

Concept Introduction:

When the ratio of number of protons to number of neutrons is not equal in a nucleus, it is considered unstable and there is dissociation to smaller fragments to make them stable which also release alpha, beta or gamma particles.

There are 48 pairs of students in the following table. Each pair has quantitatively determined the mass of taurine in a 250 mL can of the popular energy drink marketed as “Munster” using High Performance Liquid Chromatography (HPLC). The class results are presented below: QUESTION: Summarise and report these results including an indication of measurement uncertainty. In both calculation samples calculate if an outlier is present, max value, number of samples, mean, standard deviation, g (suspect), g (critical) and t (critical).
