Gas evolution reaction
A gas evolution reaction is a chemical reaction in which one of the end products is a gas such as oxygen or carbon dioxide.[1][2] Gas evolution reactions may be carried out in a fume chamber when the gases produced are poisonous when inhaled or explosive.
Examples
- A replacement reaction concerning zinc metal and hydrogen chloride:
- Zn + 2 HCl → ZnCl
2 + H
2 (gas) - In this example, hydrogen gas in diatomic form is released.
- A replacement reaction where gaseous hydrogen chloride and fluorine gas react to release diatomic chlorine gas (because fluorine is more electronegative):
- 2 HCl + F
2 → 2 HF + Cl
2 (gas)
gollark: Revise/consider/etc based on *what* though?
gollark: Do humans even *have* goals which we rationally try to long-term-maximize like that?
gollark: Can you not have a *sophont* paperclip maximizer in this universe then?
gollark: Are you just meant to act *as if* they are? Because that doesn't sound very... accurate to reality.
gollark: I remember reading about the AI box thing, but I don't know how it's meant to actually work as an experiment, given that the people are presumably aware that the other person is *not* a superintelligent AI and cannot do much to them.
