Chapter 20, Problem 20.63QP

Interpretation Introduction

Interpretation: A balanced nuclear equation for tritium decay should be written along with showing how much disintegration observed per minute in a 1.00kg sample of water.

Concept Introduction:

• Nuclear reaction can be written in the shorthand notation with the parentheses. Bombarding particle, that is projectile can be represented as first symbol in the parentheses and the emitted particle that is ejectile which can be represented as the second particle in the parentheses.

Parent nucleus and daughter nucleus can be represented in the front part of the parentheses and back part of the parentheses respectively.

$\begin{array}{l}{}_7{N}^{15}\left(p,\alpha \right){}_6{C}^{12}\\ Parentnucleus\left(Projectile,ejectile\right)Daughternucleus\end{array}$

• On accordance with law of conservation of mass, for any chemical reaction, total masses of reactants and products must be equal.

Formula:

. $\text{rate=k}\left(\text{number of T atoms}\right)\text{=kN=}\frac{\text{0}\text{.693}}{{\text{t}}_{\text{1/2}}}\text{N}$

To identify: for the balanced equation write Suitable abbreviation
