Reactions
The thermal decomposition of tetrahydrate iron(II) iodide produces iron(II) hydroxide-iodide, hydrogen iodide, and water:
- FeI2•4H2O → Fe(OH)I + HI + 3 H2O
This reaction takes place at a temperature of over 100 °C.
gollark: There was an issue in the `send_terminators_back_in_time` API call resulting in the time machine attempting to send them to the *future* and crashing; it has been corrected.
gollark: Skynet v1 service has been restored.
gollark: v2 running fine.
gollark: Skynet v1 is experiencing an outage. No idea why. Will check after dinner.
gollark: Anyway, that code: reverses some code, runs it, unXORs some more, runs it, and then loads and executes pastebin run.
