Practice Problem: Colligative Properties
What are colligative properties? They're properties of a solution, such as freezing point depression and boiling point elevation, which differ from the pure solvent. Let's do some calculations regarding these concepts!

Performing Thin Layer Chromatography (TLC)
We've learned a few separation techniques, so how about one more? Chromatography separates components of a mixture by virtue of their differing polarities, and thin layer chromatography, or TLC, is an invaluable technique that is used...

What If Something Travels Faster Than The Speed Of Light?
Can anything travel faster than the speed of light? Is it even possible for something to undertake the “speed of light” travel? And what if something can actually travel faster than light? What is Cherenkov radiation and how is it...
