CHEM 1114 - Introduction to Chemistry is designed for a one-semester introductory chemistry course. For many students, this course provides their first introduction to chemistry. As such, this textbook provides an important opportunity for students to learn some of the core concepts of chemistry and understand how those concepts apply to their lives and the world around them. The text has been developed to meet the scope and sequence of most introductory chemistry courses, including an initial emphasis on the skills required (chapter 1 and 2) for the laboratory portion of the course.

The laboratory content of the course is divided into six topics, each with a unique focus. Each topic is presented in two sessions: (1) a case-study session and (2) a laboratory session. These sessions meet in succession and are designed so that focus topics are introduced in the case-study and extended in the laboratory. In case study, the relevance of chemistry to the focus topic is developed and experimental strategies and methods are discussed and demonstrated. In the laboratory, students conduct experiments, acquire data, and analyze results to further their understanding of the selected chemical systems. Please check the course syllabus for the specific dates of the case study and laboratory meetings and check MyUI for your meeting time and room assignment information. MyUI is available at https://myui.uiowa.edu/my-ui/home.page. The course syllabus can be obtained on the CHEM:1120 course web page which can be accessed through Iowa Courses Online (ICON) available at http://icon.uiowa.edu.

Cadmium is element number 48. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

Here it is - five grams of caesium in water... But did you know caesium (aka cesium) is also used to define the length of a second? This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

In our first video about caffeine, Dr Rob Stockman extracts the molecule from six cups of coffee. Video also features Professor Martyn Poliakoff and Dr Samantha Tang.

Here's an update of our video about the element Calcium. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

Californium is element number 98. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

Paul Andersen describes the history of calorimetry and explains how it can be used to measure energy changes in a system. The specific heat of water is well established and so as a system releases or absorbs energy from a surrounding water bath it can be measured.

The video resource "Calorimetry: Crash Course Chemistry #19" is included in the "Chemistry" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Part II of our in-depth look at carbon dioxide, a moleculeoften associated with global warming.

You've probably seen carbon dioxide as a gas and solid but it is much rarer as a liquid.

We take a look at Carbon - one of the most important elements for our lives on Earth. We look at various forms of elemental carbon, from diamonds to exotic graphene and buckyballs. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

In this video Paul Andersen explains how the three types of catalyst classes act to speed up reactions. Acid-base catalysts either add or remove a proton from one of the reactants. Surface catalysts provide active sites where reactants can adsorb and create more successful collision.

Paul Andersen explains how catalysts can speed up a reaction without being consumed in the reaction. Catalysts can lower the activation energy of reaction be stabilizing the transition state. They can also create new reaction pathways with new reaction intermediates that lower the overall activation energy.
