Question
Chapter 14, Problem 14.84PAE
Interpretation Introduction
Interpretation:
a. Write the equation for the successive events happening in BNCT on absorption of a neutron.
b. Alpha emission inhaled with 239Pu causes cancer of lungs but alpha emission in BNCT destroys the cancer tumour. Give a reason for this.
Concept Introduction: InBoron neutron capture theory (BNCT), 10B absorbs a neutron, producing a nucleus that decays by alpha emission.

a
A chemist titrates 70.0 mL of a 0.7089 M hydrocyanic acid (HCN) solution with 0.4574M KOH solution at 25 °C. Calculate the pH at equivalence. The pK of
hydrocyanic acid is 9.21.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.
