Hi everyone! My name is Clarissa Sorensen-Unruh, and I am a new Lead Contributor/Blogger for the Two-Year College component of ChemEd Xchange. I am beyond thrilled, though, to join ChemEd Xchange and learn more about your interests on this platform. I am hoping you, as the audience, will help guide the topics I write about so that we can focus our discussions to interests both you and I share.
Have you ever seen the liquid nitrogen cloud? Do you wonder how the cloud forms when hot water is thrown onto liquid nitrogen? This post explores the liquid nitrogen cloud and possible explanations for its formation.
The solution to "Chemical Mystery #16: A Red, White, and Blue Chemistry Trick for You!" is presented. How this experiment can be used as a springboard to carry out a simple quantitative analysis of salt solubility is also discussed.
Watch this video and see if you can figure out how red, white, and blue colors can all be made from the same chemical solution!
Lawrence Technological University’s Marburger STEM Center recently collaborated with students enrolled in the Media Communications Program to develop a new 30-min student film, Women Untold, which celebrates the important contributions of three women of color in STEM (science, technology, engineering and mathematics).
The solution to Chemical Mystery #15: The Leaky Cup is shown here.
Time for a new chemical mystery! Watch the video below and see if you can use your chemical knowledge to figure out how this experiment is done.
It is not known why people develop allergies to nickel and there is no cure. The best course of action to prevent an allergic reaction is to avoid contact with products containing nickel. This article will explain how to make an easy and cheap nickel detection device that will limit or eliminate the risks of exposure to sources of nickel using some interesting classic chemistry.
Bill Hammack, Michael Faraday, and the timeless beauty of the science behind the combustion of a candle. "There is no more open door by which you can enter into the study of science than by considering the physical phenomena of a candle," Michael Faraday.
Chemistry is difficult to learn. Walk into any chemistry classroom, and you’ll be soon confronted with many abstract concepts. Abstract ideas have no physical form, and as a result, they are difficult to understand.
