Chapter 20, Problem 20.100QP

(a)

Interpretation Introduction

Interpretation:

Phosphorus-32 decays by emission of beta particle. The half-life of Phosphorus-32 is 14.28d.

The balanced equation for decomposition of Phosphorus-32 has to be written.

(b)

Interpretation Introduction

Interpretation:

Phosphorus-32 decays by emission of beta particle. The half-life of Phosphorus-32 is 14.28d.

The quantity of ${\text{K}}_{\text{3}}\text{P}{\text{O}}_{\text{4}}$ remains after 37d has to be calculated and the percentage of the pile undergoes for decay should be identified.
