Question
Chapter 10, Problem 25Q
Interpretation Introduction
Interpretation:
What are food miles has to be found. The favorite foods have to be selected and a food mile analysis has to be made. The ways by which food miles can be reduced have to be found. Whether it is important to do or not has also to be found.
Concept Introduction:
Food mile analysis:
Mile is the unit of distance that refers to the distance travelled during the journey from producer to consumer in transporting of food. From the analysis of food mile some important assessments can be made such as environmental impact of food and impact on global warming.

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.
