Chapter 20, Problem 34E

(a)

Interpretation Introduction

Interpretation:

The reason that 40Ar/40K ratios are used to date material rather than 40Ca/40K ratios is to be determined.

Concept Introduction:

The decaying of particle can be called as spontaneous process in which one unstable subatomic particle transforms into multiple other particles. The particles which are created by this process will have less mass in comparison of the original particle.

(b)

Interpretation Introduction

Interpretation:

The assumptions which are taking into consideration for using this technique are to be determined.

Concept Introduction:

The decaying of particle can be called as spontaneous process in which one unstable subatomic particle transforms into multiple other particles. The particles which are created by this process will have less mass in comparison of the original particle.

(c)

Interpretation Introduction

Interpretation:

The age of rock is to be calculated.

Concept Introduction:

The decaying of particle can be called as spontaneous process in which one unstable subatomic particle transforms into multiple other particles. The particles which are created by this process will have less mass in comparison to the original particle.

(d)

Interpretation Introduction

Interpretation:

The method which is used to measure the age of rock compared with the actual age if some 40Ar has escaped from the sample is to be determined.

Concept Introduction:

The decaying of particle can be called as spontaneous process in which one unstable subatomic particle transforms into multiple other particles. The particles which are created by this process will have less mass in comparison to the original particle.

Blurred answer

The Handbook of Chemistry and Physics gives solubilities of the following compounds in grams per 100 mL of water. Because these compounds are only slightly soluble, assume that the volume does not change on dissolution and calculate the solubility product for each. (a) BaSeO4, 0.0118 g/100 mL
Can I please get help with answering this?
These are in the wrong boxes.  Why does the one on the left have a lower molar mass than the one on the right?
