10 Incredible Chemical Reaction GIFs Explained

10 Incredible Chemical Reaction GIFs Explained
We encounter thousands of chemical reactions every day: plants use them in photosynthesis, metals rust over time, and combustion reactions provide us with heat and light, among thousands of other daily uses. Chemical reactions occur when reactants transform into new substances, called products, through creating and breaking bonds between atoms. Sometimes the process creates some pretty wild effects. Check out our top 10 chemical reactions below: 1) Disintegration (Mercury Reacts with Aluminum) Image credit: Theodore Gray via Youtube When aluminum rusts, it creates a protective oxide layer that prevents the aluminum atoms underneath from further rusting. 2) Pharaoh's Serpent (Mercury (II) Thiocyanate Reacts with Oxygen) Image credit: tenkowal via Youtube The reaction depicted above, nicknamed the "Pharoah's Serpent," actually use to be a common classroom demonstration. 3) Explosive Gummi Bear (Heated Potassium Chlorate Reacts with a Gummi Bear) Image credit: ebaum via ebaumsworld.com

Protein Data Bank - RCSB PDB A Structural View of Biology This resource is powered by the Protein Data Bank archive-information about the 3D shapes of proteins, nucleic acids, and complex assemblies that helps students and researchers understand all aspects of biomedicine and agriculture, from protein synthesis to health and disease. As a member of the wwPDB, the RCSB PDB curates and annotates PDB data. Build an Atom - Phet Topics Atoms Atomic Structure Isotope Symbols Atomic Nuclei Description Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas! GNU XaoS - GNU XaoS XaoS is an interactive fractal zoomer. It allows the user to continuously zoom in or out of a fractal in a fluid, continuous motion. This capability makes XaoS great for exploring fractals, and it’s fun!

Dark matter is the thread connecting galaxy clusters Simulations of the Universe on the largest scales show an unexpected resemblance to nerve cells in the human brain, with galaxy clusters playing the role of the cell body and thinner filaments of matter linking them like axons. Galaxy surveys (such as the Sloan Digital Sky Survey, or SDSS) show that galaxies do cluster like our simulations predict. But the filaments that should connect them have been harder to find. Most of the mass in the Universe is dark matter—material that neither emits nor absorbs light—and filaments are predicted to be mostly dark matter: no galaxies, little hot gas. Einstein's general theory of relativity, however, tells us mass affects the path of light, and a group of astronomers have identified a dark matter filament by measuring this effect. Jörg P.

We have been having fun with apple books and crafts and decided to do a little apple experimenting too. The kids love acid and base reactions, but this time instead of combining them we observed to see what effects they would have on apples. We began by choosing which acids and bases we were going to use. The acids were easy, lemon juice and vinegar are two we always have, but I didn’t know of any bases other than baking soda!

The Molecular View of Equilibrium Text below taken from Kinetic Theory of Gases: Molecular Speeds Other sections state that increasing the temperature increases the speeds at which molecules move. We are now in a position to find just how large that increase is for a gaseous substance. Combining the ideal gas law with Eq. (1) from The Total Molecular Kinetic Energy, we obtain or Since N is the number of molecules and m is the mass of each molecule, Nm is the total mass of gas.
