Chapter 21, Problem 45E
Interpretation Introduction

Interpretation:

The heat released per mole of Fe2O3 produced is to be calculated. The energy released when 2 mol of proton and 2 mol of neutron combine to form 1 mol of alpha particles are to be calculated and compared with the thermal energy of Fe2O3 produced.

Concept introduction: When two nuclei fuse with each other at extremely high temperature and pressure, such reactions are known as thermonuclear reactions. When light nuclei fuse into heavier nuclei then energy is produced. The energy produced by the sun is possible because of this type of reactions.

To determine: The heat released per mole of Fe2O3 produced and the energy released when 2 mol of proton and 2 mol of neutron combine to form 1 mol of alpha particles. The comparison of both the energy released.

A small artisanal cheesemaker is testing the acidity of their milk before it coagulates. During fermentation, bacteria produce lactic acid (K₁ = 1.4 x 104), a weak acid that helps to curdle the milk and develop flavor. The cheesemaker has measured that the developing mixture contains lactic acid at an initial concentration of 0.025 M. Your task is to calculate the pH of this mixture and determine whether it meets the required acidity for proper cheese development. To achieve the best flavor, texture and reduce/control microbial growth, the pH range needs to be between pH 4.6 and 5.0. Assumptions: Lactic acid is a monoprotic acid H H :0:0: H-C-C H :0: O-H Figure 1: Lewis Structure for Lactic Acid For simplicity, you can use the generic formula HA to represent the acid You can assume lactic acid dissociation is in water as milk is mostly water. Temperature is 25°C 1. Write the K, expression for the dissociation of lactic acid in the space provided. Do not forget to include state symbols.…
