Comprehensive art program

Our art program is designed to enhance students’ understanding of concepts through clear, effective illustrations, diagrams, and photographs.

.. .. .. .. .. .. ..

Interactives that engage

Chemistry incorporates links to relevant interactive exercises and animations that help bring topics to life through our Link to Learning feature. Examples include:
  • PhET simulations
  • IUPAC data and interactives
  • TED talks

Assessments that reinforce key concepts

In-chapter Examples walk students through problems by posing a question, stepping out a solution, and then asking students to practice the skill with a “Check Your Learning” component. The book also includes assessments at the end of each chapter so students can apply what they’ve learned through practice problems.

Atom-first alternate sequencing

Chemistry was conceived and written to fit a particular topical sequence, but it can be used flexibly to accommodate other course structures. Some instructors prefer to organize their course in a molecule-first or atom-first organization. For professors who use this approach, our OpenStax Chemistry textbook can be sequenced to fit this pedagogy. Please consider, however, that the chapters were not written to be completely independent, and that the proposed alternate sequence should be carefully considered for student preparation and textual consistency. We recommend these shifts in the table of contents structure if you plan to create a molecule/atom-first version of this text for your students:

  • Chapter 1: Essential Ideas
  • Chapter 2: Atoms, Molecules, and Ions
  • Chapter 6: Electronic Structure and Periodic Properties of Elements
  • Chapter 7: Chemical Bonding and Molecular Geometry
  • Chapter 8: Advanced Theories of Covalent Bonding
  • Chapter 3: Composition of Substances and Solutions
  • Chapter 4: Stoichiometry of Chemical Reactions
  • Chapter 5: Thermochemistry
  • Chapter 9: Gases
  • Chapter 10: Liquids and Solids
  • Chapter 11: Solutions and Colloids
  • Chapter 12: Kinetics
  • Chapter 13: Fundamental Equilibrium Concepts
  • Chapter 14: Acid-Base Equilibria
  • Chapter 15: Equilibria of Other Reaction Classes
  • Chapter 16: Thermodynamics
  • Chapter 17: Electrochemistry
  • Chapter 18: Representative Metals, Metalloids, and Nonmetals
  • Chapter 19: Transition Metals and Coordination Chemistry
  • Chapter 20: Organic Chemistry
  • Chapter 21: Nuclear Chemistry

Ancillaries

OpenStax projects offer an array of ancillaries for students and instructors. The following resources are available.

  • PowerPoint Slides
  • Instructor’s Solution Manual

After a one-year postdoctoral appointment at Los Alamos National Laboratory, he joined the University of North Carolina–Pembroke in the fall of 1989. Dr. Flowers teaches courses in general and analytical chemistry, and conducts experimental research involving the development of new devices and methods for microscale chemical analysis.

Klaus Theopold, PhD, University of Delaware
Dr. Klaus Theopold (born in Berlin, Germany) received his Vordiplom from the Universität Hamburg in 1977. He then decided to pursue his graduate studies in the United States, where he received his PhD in inorganic chemistry from UC Berkeley in 1982. After a year of postdoctoral research at MIT, he joined the faculty at Cornell University. In 1990, he moved to the University of Delaware, where he is a Professor in the Department of Chemistry and Biochemistry and serves as an Associate Director of the University’s Center for Catalytic Science and Technology. Dr. Theopold regularly teaches graduate courses in inorganic and organometallic chemistry as well as General Chemistry.

Richard Langley, PhD, Stephen F. Austin State University
Dr. Richard Langley earned BS degrees in Chemistry and Mineralogy from Miami University of Ohio in the early 1970s and went on to receive his PhD in Chemistry from the University of Nebraska in 1977. After a postdoctoral fellowship at the Arizona State University Center for Solid State Studies, Dr. Langley taught in the University of Wisconsin system and participated in research at Argonne National Laboratory. Moving to Stephen F. Austin State University in 1982, Dr. Langley today serves as Professor of Chemistry. His areas of specialization are solid state chemistry, synthetic inorganic chemistry, fluorine chemistry, and chemical education.

what's molarity?
Okpaka Reply
the concentration of a substance in solution, expressed as the number moles of solute per litre of solution

Please help me solve this question. A is a solution of 0.995mol/dm cube hydrochloride acid. B was prepared by diluting 10cm cube of a saturated solution of sodium trioxocarbonate (iv) to 100cm cube at room temperature. Assuming that 21.50cm cube of A reacted with 25cm cube of B. Calculate: i. Concentration of solution B in mol/dm cube. ii.Solubility of sodium trioxocarbonate (iv) at room temperature. Equation of the reaction: Na2Co3 +2HCL------> 2NaCL +H2O +CO2.

I don't know whether it's ok or not, but the answers I got are: I. 0.428 mol/dm^3 II. 4.54g per 100 g of water
Nazifa
In the first one, I first found out the amount of HCl in mol using moles=concentration x volume. Then I checked the ratio of Na2CO3 to HCl, which is 0.5 to 1. Therefore the moles of Na2CO3 will be half of HCl. Using the amount in moles and the volume as 25 cm^3, I reached my answer!
Nazifa
In the second one, it says that 10 cm^3 has saturated Na2CO3 solution. Using the concentration we found in previous answer, I found out the moles present in 10cm^3. After that, using mass= moles x RFM, I got it's mass. As for the mass of water, we know 1 cm^3 gives 1g, so 10 cm^3 gives 10g.....
Nazifa
Using solubility= mass of solute/mass of solvent x 100, we reach the answer.
Nazifa
Note: we will not use the volume of solution to be 100 cm^3, because then the solution will be dilute.
Nazifa
plz do correct me if I'm wrong!! ☺️

is like the answer is 900

Define reduction in term of loss or gain of oxygen or hydrogen give an example.
Aneela
CuO + Mg → Cu + MgO removing oxygen is reduction. here Mg is reducing agent(loss of electrons)
Haider
reduction >> reduc(+)ion mean (+)ion reduced mean electron gained by (+)ion (+)ion means H(+).
