A chemistry kit containing lab equipment and a large amount of manganese dixoide and hydrogen peroxide.

2 H[sub]2[/sub]O[sub]2[/sub] ----(MnO[sub]2[/sub])----> 2 H[sub]2[/sub]O + O[sub]2[/sub]

Hey, OP said we can't bring oxygen. He never said anything about making our own.

Chemistry major FTW.

Fancy Pants!

OT: I'unno. Probably somebody like fancy pants here, and that stuff, to keep me alive.

What can I say? I'm good.

I saw that in an episode of Hell Girl as well. They trapped someone in a giant Erlenmeyer flask and said they were going to synthesize oxygen. But instead of manganese dioxide, they added calcium carbonate and instead of hydrogen peroxide they added hydrochloric acid. Not a good combo at all. Especially in a sealed environment.

Observe:

CaCO[sub]3[/sub] + 2 HCl ----> CaCl[sub]2[/sub] + CO[sub]2[/sub] + H[sub]2[/sub]O

Carbon dioxide. Asphyxiant gas. The absolute worst thing you want to make in a sealed area.

Where is all the Mn going?

Manganese is a catalyst in the decomposition of hydrogen peroxide. It is not used up in the reaction, it only speeds it up.

Though this is not part of the problem wouldn't the Mn eventually crush you or the water drown you? Well done though very creative.

Theoretically, if I performed the synthesis enough, yes. However, I'm fairly certain that catalysts are able to be distilled out of liquids, dried and used again. Now the water is a bit more problematic, but hopefully I'd be picked up before then.

Yeah, if the water gets in to your lungs either as a gas or liquid your so boned.

Well, the water synthesized in the reaction is in liquid form, so I would be able to contain it in...something, I guess. A container of some sort. Maybe the glassware I'm not using from the lab kit.

A container of some kind huh? OH! How about the space pod.... oh wait.

That would kind of defeat the purpose of making oxygen. Fortunately, a lot of decomposition of hydrogen peroxide would have to take place for any water produced to be a threat. And since the reaction would be taking place inside a flask of some kind, water would be contained while the oxygen produced would escape from the flask into the pod.
