Happy National Chemistry Week! This year’s theme is “Sticking with Chemistry,” a celebration of the science of glues and adhesives. It’s no coincidence that today is also Mole Day, the annual festival honoring Avogadro’s Number – the number of molecules or atoms that comprise a mole of a substance: 6.02 x 1023. That’s 602,000,000,000,000,000,000,000 molecules or atoms!
On the chemistry of glue, here’s an infographic from Compound Interest:
Looking for some sticky science to try at home? Here’s an ACS Reactions video (with consulting contribution from our own Dr. Alicia McGeachy!) all about making magnetic slime:
Finally, it’s hard to believe, but this is our seventh year posting on Mole Day and/or National Chemistry week! Here’s a little tour down memory lane:
- 2019: National Chemistry week & Mole Day: Marvelous Metals
- 2018: Mole Day (how many moles are in a cubic nanometer?)
- 2017: How many moles of gas are in a Pokémon Gastly? (Halloween post!)
- 2017: National Chemistry Week: Chemistry Rocks!
- 2016: National Chemistry Week & Mole Day (how a computational chemist uses moles)
- 2015: National Chemistry Week: Chemistry Colors our World/Mole Day & Enhancing Color: Quantum Dot Televisions
- 2014: Happy Mole Day from the CSN! (with doughnuts)
