Why is it avocados turn brown so quickly, and what can you do to stop it happening? This graphic and post have the answers: http://wp.me/p4aPLT-p9(This is also one of the graphics that’ll be appearing in modified form in the Compound Interest book next year!)

All of the coolest things you could ever want to know about Helium. 

All of the coolest things you could ever want to know about Helium. 

My first in a new line of chemistry posters that I am making. 
I didn’t cite my sources on this first one but I did use “Nature’s Building Blocks” By John Emsley and supplemental information from this website… http://imagine.gsfc.nasa.gov/docs/ask_astro/answers/961112a.html
Enjoy!

It’s been a little while since the last entry in the ‘Everyday Compounds’ series; today’s entry looks at sodium hypochlorite, found in household bleach, and used to chlorinate swimming pools.
The accompanying article also details why, aside from the obvious reasons, getting three million people to urinate in a swimming pool would be a bad idea: http://wp.me/p4aPLT-ml

EDIT: via cyclopentadiene

From the paper on C2N14 (that one with three -N3 groups on the substituted tetrazole):

Translation: “Taking an IR of this thing was enough to make it blow up.”

High nitrogen = boom!

With American Independence Day around the corner, and the customary fireworks, here’s a look at the chemistry of gunpowder and its role in pyrotechnic displays: http://wp.me/p4aPLT-lMAdapted from the quick and dirty graphic I created for the ask from wonderousscience - note that in that graphic, I accidentally swapped the percentages for potassium nitrate and charcoal! This graphic shows the correct percentages.
