Nitrogeno

The way every Italian reacts to seeing the word "Nitrogen" because apparently in 2021 no non-chemist Italian whatsoever understood that "Nitrogen" is actually "Azoto" in italian and not "Nitrogeno".

Italian non-chemist: HA APPENA MESSO IL DITO NEL NITROGENO LIQUIDO, QUESTO È PAZZO
Italian chemist: SI CHIAMA AZOTO. Giuro che se dici un'altra volta "Nitrogeno" ti ammazzo.

Smart man's liquid nitrogen

Smart man's liquid nitrogen is dry ice mixed with 1,1-Difluoroethane. The boiling point of 1,1-difluoroethane is -11.29°F (-24.05°C) while it's melting point is -178.6°F (-117°C). The sublimation point (the point at which a substance sublimes, or goes from a solid directly to a gas) of dry ice (solid carbon dioxide) is -109.2°F (-78.46°C). Smart man's liquid nitrogen stays at around -78°C as long as you keep supplying more dry ice. Then the dry ice runs out and it heats up until it reaches -25°C where it becomes homeless man's liquid nitrogen. Then the 1,1-Difluroethane (can be found in computer duster) slowly boils away until it becomes gaseous 1,1-Difluoroethane. You can keep chemical reactions cool with smart man's liquid nitrogen and once it becomes homeless man's liquid nitrogen, you can use a funnel and a plastic soda bottle to store the liquid difluoroethane under pressure and label it and put it in the lab freezer.

I kept my chemical reaction extra cool with smart man's liquid nitrogen.

Another way to say Hentai with periodic table elements. Also another was to be called smart-ass by your friends.

(insert hentai orgy)

Nitrogen

Seventh element on the periodic table. Makes about 78% of earth's atmosphere. Used in stuff like amonia and plant fertilizers, and found in proteins, so you need it.

Nitroglycerin, a major explosive, contains nitrogen.
