lol@11s

I never learned my periodic table well, but is there even a hydrogen-16?

death makes me laugh

The 16 means the number of hydrogen atoms in the molecule.

Dear god...

This was a collirium's blueprint or sumthin like that.
Old shit is old.

No. It only gets up to three before all further isotopes are radioactive, and pretty much have a half-life of "instant". Furthermore, that weight for Nitrogen is completely impossible- it can't be that light and still be Nitrogen.

I suspect the artist simply switched around the position by accident, and meant for those to be counts, not isotopes.

i read C13H16N2 as China for some reason.

Think before you post please.

Tetrahydrozoline Hydrochloride
C13H16N2•HCI

Here's a more Japan chart.

I THINK ANON NEEDS A LESSON ON ATOMIC NOTATION

I skipped HS to become a shut-in, and thus I have no idea what the fuck these letters or numbers mean.

So why are they talking about Visine, anyhow?

I'm a highschool dropout and even I know what they mean.

Prove it.

They mean SCIENCE!

>Tetrahydrozoline is an alpha agonist and its main mechanism of action is the constriction of conjunctival blood vessels. This serves to relieve the redness of the eye caused by minor ocular irritants.

>>863633
Is that even possible?

THAT'S THE STUFF IN MY EYEDROPS

Because rabbits have red eyes.

Here's a diagram of the molecule. Each corner of the rings represents a carbon atom; double lines are double bonds. The N's mean there's a nitrogen atom in place of the carbon. Hydrogen molecules are not shown since they're assumed to fill in any empty orbitals.

what's the H, then?

>>863982
It's bonded to nitrogen, and non-hydrocarbon parts of the molecule are different. Most organic molecules are almost completely chains of carbon and hydrogen, so it's convenient to draw them like that.

Tetrahydrozoline is a derivative of imidazoline, which is found in over-the-counter eye drops and nasal sprays. Other derivatives include naphazoline, oxymetazoline, and xylometazoline. Poisoning can result from an overdose.

Tetrahydrozoline is widely believed to cause violent diarrhea if administered orally, as in a few drops of Visine in an unsuspecting person's beverage. However, this is an urban legend, and the actual results may vary from severe nausea and vomiting to seizures or a coma.[1] Diarrhea is not a side effect.
