SN2 Reactions: Nucleophiles, Electrophiles, Leaving Groups Chemistry in a Nutshell 2025-10-06 | Let's break down the SN2 reaction mechanism step-by-step, showing exactly how a nucleophile attacks an electrophile, how the leaving group departs, and why the whole process leads to steric inversion. Using clear diagrams and curved arrows, we'll walk through how to predict products, avoid common mistakes, and decide when SN2 CAN'T happen.

How the Quantum Mechanical Model of the Atom Was Born Chemistry in a Nutshell 2025-07-28 | The Bohr model of the atom couldn't explain everything, especially when it came to electron behavior. See how that early model gave way to a new understanding of atomic orbitals, shaped by groundbreaking work from Louis de Broglie, Werner Heisenberg, Erwin Schrödinger, and Paul Dirac. From wave-particle duality to the uncertainty principle, from electron probability clouds to relativistic equations, you'll discover how each of these physicists contributed to the creation of the quantum mechanical model of the atom.What is an atom?

States of Matter Explained in Depth by a Chemist: Solid, Liquid, Gas Chemistry in a Nutshell 2024-07-01 | Learn about the three main states (phases) of matter: solid, liquid, and gas. We'll talk about their unique characteristics such as shape, volume, and compressibility, as well as phase transitions. Matter is anything that takes up space and has mass. It's the "stuff" all around us. To bring the lesson to life, we'll end with a nostalgic story about how dry ice was used to keep ice cream cold in the 1980s by utilizing its unique property of sublimation.Watch the whole playlist: youtube.com/playlist?list=PLvUW25kBaMMssGHFrR4Ee7_-8cFBvBkgNPLAYLISTS:youtube.com/playlist?list=PLvUW25kBaMMs9m0GL4dz8jSs0K4PWfqCpyoutube.com/playlist?list=PLvUW25kBaMMvs5nsG1VUQA0wsP9LGEQhayoutube.com/playlist?list=PLvUW25kBaMMuKRkW9gDV7vlAk4Y9WRU7cyoutube.com/playlist?list=PLvUW25kBaMMuHwUffHLOozSFQ0Cz_iTnCyoutube.com/playlist?list=PLvUW25kBaMMv7_3jTEAe3vVZqPhsjf5Oyyoutube.com/playlist?list=PLvUW25kBaMMtc45U4K2b0Dm88L9D7d0EEPATREON: patreon.com/c/ChemistryinaNutshellTime Stamps0:00 Intro0:46 Solids2:23 Melting/Freezing2:48 Liquids3:53 Boiling/Condensing4:23 Gases5:12 Solid to Gas Transition/Sublimation/Deposition5:28 Sublimation Story Time!Image Credits:pixabay.com/photos/ice-cubes-ice-frozen-cold-3506782Photo by Emiliano Arano: pexels.com/photo/photography-of-barrel-wave-1298684pixabay.com/illustrations/clouds-sky-cumulus-air-atmosphere-7081496commons.wikimedia.org/wiki/File:Modern_vegas_vic_souvenirs.JPGFree B-Roll by Videezy! http://videezy.comPhoto by richie squires: pexels.com/photo/brown-glass-bottle-with-a-white-background-10607591pixabay.com/photos/to-bake-icecake-cakes-ice-cream-1003685pixabay.com/photos/flame-fire-light-candle-flame-burn-1062513#PhasesOfMatter #ScienceEducation #DryIce #Chemistry #PhaseChanges #ScienceClass #EducationalVideo #Sublimation #SolidsLiquidsGases #IceCreamStory

Precipitation of a Supersaturated Solution Chemistry in a Nutshell 2022-04-23 | A supersaturated solution contains more than the maximum amount of solute than is capable of being dissolved at the current temperature. I dissolved sodium acetate in hot water, then allowed it to cool. At this lower temperature, it’s an inherently unstable solution, so the only thing I needed to do to get a precipitation reaction to start was to add a few crystals of solid sodium acetate.#chemistry #chemistryeducation #chemistrylab
How Luminol Works: Chemiluminescence Chemistry in a Nutshell 2022-04-16 | Watch a light-producing chemical reaction while learning about what's happening. Chemiluminescence is when a chemical reaction generates light with little or no heat. When luminol and the other chemiluminescent compounds are produced, they contain excited electrons. When the compounds are reacted with an appropriate oxidizing agent, the electrons relax to a lower energy state, releasing energy in the form of light. Forensic investigators use luminol to detect trace amounts of blood at crime scenes because it reacts with the iron in hemoglobin to produce light. It’s a very powerful forensic tool because it’s capable of detecting bloodstains that were diluted up to 10,000,000 times and it does this without interfering with subsequent DNA testing.
