Chapter 20.1, Problem 20.1CC

(a)

Interpretation Introduction

Interpretation:

Two samples of water, each made up of different isotopes of hydrogen. One has ${}_{\text{1}}^{\text{1}}{\text{H}}_{\text{2}}\text{O}$ and other has ${}_{\text{1}}^3{\text{H}}_{\text{2}}\text{O}$; using this account given set of statements has to be explained.

Concept introductio n:

Isotopes are defined as the element that has same atomic number (Z) but different mass number (A).

Example:

Isotopes of hydrogen are ${}_{\text{1}}^{\text{2}}\text{H},{}_{\text{1}}^{\text{2}}{\text{H and }}_{\text{1}}^3\text{H}$.
