I don't know if it really fits in here, but I was wondering something the other day. Imagine you have a completely sealed small transparent room completely filled with chlorine gas, that doesn't contain a ppb of anything else. Now imagine I'm able to teleport a chunk of pure sodium in there, that is in perfect stoichiometry with the chlorine gas. Would the reaction start instantaneously? If I would leave and come back an hour later, would there - if you neglect the iodine in real table salt - be a pile of table salt at the bottom of the room? Is this a realistic way to produce it, or can it only be achieved through electrolysis?
