Implementing a Process-Oriented Guided Inquiry Learning (POGIL) style recrystallization activity provides students with an opportunity to actively engage in the learning process while reinforcing key chemical concepts such as polarity, solubility, and purification techniques.
The conversion of adenosine triphosphate (ATP) into adenosine diphosphate (ADP) is an extremely important energy source for living organisms. Under common physiological conditions, it can be expressed as:
Would you like to take a walk with me through the chemical winter wonderland of snowflakes? Well, we chemists know that the stunning six-sided symmetry of snowflakes (Figure 1) results from repeated arrangement of water molecules into a hexagonal crystal structure (Figure 2).
Galinstan is the tradename for a liquid metal alloy that is comprised of three elements: gallium (68.5%), indium (21.5%), and tin (10%).1 It behaves a lot like mercury but has significantly lower toxicity. Because of this, Galinstan is used as a replacement for mercury in a variety of applications.
