Tuesday Trivia – Answer for October 16, 2018

During National Chemistry Week, we’re continuing our trivia with an “Out of this World” focus.

Just a reminder of last week’s post:

An interesting study at the University of Georgia revealed the major component of interstellar clouds to be:

(a) Hydrogen and helium atoms
(b) Mothballs
(c) My dreams
(d) Ammonia
(e) Carbon Monoxide

Answer: mothballs

A handful of researchers measured infrared emission from some interstellar clouds and found a measurable concentration of gas-phase naphthalene, which is the main compound in mothballs. Just to clarify, naphthalene is pretty flammable so modern day mothballs are primarily composed of 1,4-dichlorobenzene, but older mothballs contained lots of naphthalene.

It’s only the third day of National Chemistry Week so you have 4 more days to celebrate the fact that chemistry is out of this world!
