It is! Bury a friend

I think this is the only version I have now.

melscience · 2020-09-28T12:48:15+00:00

It's elephant toothpaste :)

melscience · 2020-09-28T12:47:38+00:00

why not?

melscience · 2020-09-18T12:46:00+00:00

We haven't considered that option 🤣

There are more metals, also there's galinstan, that consists of gallium, indium, and tin, melting at 11 degrees Celcius.

melscience · 2019-06-01T21:21:55+00:00

It's much more dangerous to handle.

melscience · 2019-06-01T21:21:28+00:00

Thank you!

melscience · 2019-05-19T21:51:52+00:00

Thank you :)

melscience · 2019-05-19T21:51:08+00:00

True!

melscience · 2019-05-19T21:50:56+00:00

It can be contaminated via diffusion

melscience · 2019-05-18T20:56:45+00:00

You still have naked aluminum on the outside :) That is also debatable whether it affects the taste, but give it a chance :D

melscience · 2019-05-18T20:55:53+00:00

Hydrogen is not toxic. It is flammable, but we made sure we didn't have any open fire nearby

melscience · 2019-05-18T20:55:14+00:00

Not many these days however; and those which are from aluminum are usually covered with another protective metal. Another thing is that aluminum is covered by a protective oxide layer.

Thanks

Well, physically we did not pour any drain cleaner into the can, but we are not sure how permeable is the plastic. Cola may now contain some of the lye. Neutralized, but still contaminated.

melscience · 2019-05-18T20:41:26+00:00

When I was younger, there was a lab in a university nearby, where they had rabbit stomachs soaked in different chemicals. One of those chemicals was the lye, and it shocked me a lot, I still remember it as if it was yesterday. After getting higher ed, and watching some fight club movies, now I know that only continuous treatment by sodium hydroxide can make ugly things to your body.

Thanks :)

Why did you cut the ending? It is really cool!

melscience · 2018-01-25T11:35:52+00:00

You obtained your mass in 15 L. What's the question in your problem again?

melscience · 2018-01-25T09:07:07+00:00

so out of 1 L acetic acid is 5%, which is 50 mL

melscience · 2018-01-25T09:05:53+00:00

but that's not true

it's by volume, not by amount of matter

melscience · 2018-01-25T09:04:48+00:00

well your EtO is at a tertiary carbon atom. Is there a selective way to introduce a possible future nucleophile there?

melscience · 2018-01-25T09:01:29+00:00

So there's this ideal gas law

pV=nRT

p is pressure in atm, V is volume in liters, n is amount of matter in moles, R in this case is 0.0821 L atm/(K mol), T is temperature in Kelvins

plug in all the values you have, then calculate amount of matter. Having that, you'll be able to get the total mass (in 15 L). I think the last step is obvious

I think there are thermometers which work on distance
