Chemistry Workbook For Dummies, 3rd Edition
Paul Yates. Many undergraduate students enter into chemistry courses from a wide range of backgrounds, often possessing various levels of experience with the mathematical concepts necessary for carrying out practical calculations in chemistry. Chemical Calculations: Mathematics for Chemistry, Second Edition provides a unified, student-friendly reference of mathematical concepts and techniques incorporated into the context of familiar chemical topics. In solving such problems, it is necessary first to think your way through, perhaps by writing down a road map showing the relationships among the quantities given in the problem.
Then you can apply conversion factors, making sure that the units cancel, and calculate the result. The stoichiometric ratio measures one element or compound against another. The reactant of two or more reactants present in an amount such that it would be completely consumed if the reaction proceeded to completion.
Also called limiting reactant.. We say that such a reaction does not go to completion. Since I was using a hardcopy I had no navigation issues The number of grammatical errors is small, though the number of necessary corrections to the text arising from, for example, one word being run into another, is large. These corrections are noted on the list to be supplied separately.
I enjoyed reading this text; there is much to recommend it. The style is relaxed and chatty without being trite or unscientific, the examples and the questions are generally well-chosen, and the number of questions is more than enough for students to fully test their understanding. My reservations can be summed up as follows: 1.
There are many corrections, nearly all of them minor, that should be made before the text is released to the academic community at large. I am uneasy about the speed with which questions follow the introduction of a new topic. This may diminish the time students spend reflecting on a topic before they move onto new material.

However, I presume that this style of text, with a high density of questions, has been tried in chemistry before and been found to work satisfactorily, despite my concerns. The text starts at a very low level. Although it introduces a good range of fundamental topics - apart from kinetics, which should be added - it does not provide sufficient depth for many 1st year University courses. However, it be suitable for typical basic chemistry introductory courses, for which there is a considerable demand, both in Canada and in the USA.
In general this textbook has neither the breadth nor depth of content to satisfy the first year chemistry curriculum for B. The current version would be suitable for a massive online open courses MOOC , high school, introductory The current version would be suitable for a massive online open courses MOOC , high school, introductory college course for students who do not have Chem 11 or a non-science major. I would also like to point out that more content is better than less for a first-year chemistry textbook because it becomes a reference resource for students throughout their academic career.
To make the content suitable for a first year chemistry course for B. For brevity, I list only the most desirable additions to make this book suitable for a, however, there are many more minor changes that would improve the quality of the book. Please contact me if you would like more details. This book, at least the print version, suffers from numerous typos that cause both major and minor confusion. These must be fixed in order to be usable for any student. Particular attention needs to be paid towards superscripts and subscripts, and spacing because syntax is critical in chemistry.
There are some errors in the accuracy of the content as well. I think it is more appropriate to include the van't Hoff factor as an ideal value or estimate the value as somewhere between 1 and 2 probably closer to the ideal value of 2 rather than ignoring the value. From a student point of view this is especially confusing because the "Salting Pasta Cooking Water" example directly preceeds a sample calculation in which the van't hoff factor is included for a NaCl solution of similar molality.
Chapter Sulfuric acid H2SO4 is listed as a strong acid, but this is only true for the first deprotonantion and should be noted, especially because the hydrogen sulfate ion HSO4- and sulfate SO is discussed later in the book. I worry that this omission will leave students with an outdated, nineteenth century understanding of atoms and molecules. The text is clearly written and accessible to students. In some places, it would be desirable to use more technical language because students are learning to become fluent and proficient with the terms and should see technical terminology used in the correct context as much as possible.
For the students' benefit, some of the example solutions need to include more steps. The most notable inconsistency is the use of a wedged shaped bond to represent a polarized bond. This is confusing because wedge bonds are usually reserved for representing bonds coming out of the plane in VSEPR model. Conventionally, delta symbols or arr.
This text can be used modularly; however, I see this as a weakness. Modular treatment in textbooks lead to a compartmentalized understanding of the subject, which is undesirable. The text version contains regular readability issues in the form of fuzzy text.
There are also font size control issues in many instances. In a couple of instances, the html tags are present instead of formatted text. Paragraph and section spacing in the printed version could be improved to enhance organization and readability; for example, a section title that appears at the end of a page can be anchored to the section text so that it starts at the beginning of a new page. The examples that connect chemistry to the everyday experience are good. I would like to see a more global perspective by extending the context of these examples to concerns that are beyond North American boarders.
There is also very little discussion of the environment. Regardless of the cultural context, this is a leading concern for our students and society, it is important that students make the connection between chemistry and the environment. The book is text heavy and more diagrams would help to convey the ideas using a different mode, which would be useful for students who prefer pictures to words. The visuals in the book could be vastly improved in terms of appeal and quantity.
Discussion of imperial units ounces, feet, Fahrenheit etc. This is especially true for the section on unit analysis in Chapter 2. The current version is a single, gigantic file which takes forever to download and open, even on a fast computer. To be useful the book needs to be divided into separate files — one for each chapter.
The single file version allows the entire text to be searchable, but this takes a long time and often generates too many hits to be useful. In the Preface, the author tries to put chemistry in context for students by supporting the view that chemistry is the "central science", sandwiched between physics and biology. I feel this hierarchical view of the sciences is antiquated. A more modern understanding is that all the sciences and mathematics, indeed all academic disciplines, are interrelated, each discipline depending on knowledge from all other fields for inspiration and insight.
The textbook does not have a glossary, index or table of contents. This textbook is not in depth enough for science majors. However, it might suffice as a prep course for students that have never taken any highschool chemistry. In chapter 4, In chapter 4, double replacement reactions are introduced. Yet only precipitation reactions are given as examples even though some of the exercises involve strong acids reacting with weakly basic salts.
Arrhenius acid-base reactions are treated separately as neutralization reactions. Also, when single replacement and synthesis combination reactions are introduced no attempt was made to present them as examples of redox reactions. Redox reactions are treated separately at the end of chapter 4. Chapter 6 Gases , is not in depth enough. Kinetic-molecular theory is completely left out.
Chapter 7 appears to cover basic thermochemistry fairly adequately. However, thermodynamics is not covered deeper anywhere in this textbook. Chapter 8 Electronic Structure also is not in depth enough. The textbook treads very lightly on quantum mechanics. Thus, the student will never learn the contributions made by Einstein, De Broglie, Heisenberg or Schrodinger. There is a short paragraph on photon energies but no credit is given to Max Planck. In the section on periodic trends, the shielding effect and effective nuclear charge are not mentioned at all. Thus, students will get the false impression that actual nuclear charge and average distance of valence electrons from the nucleus principal quantum number are sufficient for explaining periodic trends.
In Chapter 9 Chemical Bonding , the concepts of formal charge and resonance stabilization are not discussed anywhere. In the section on molecular geometry, trigonal bipyramidal and octahedral geometries are left out altogether.
