Can any chem fags confirm this is accurate?

Ive tried googling around heaps for information on air solubility and properties of hydrogen cyanide in the air but shit only pops up stuff about the aqueous solubility of actual air and other unrelated shit. Is gaseous solubility even a thing nigger?

I dont know much about the actual supposed gas cannister mechanism but i would have assumed the gas is already formed in the cannister and it merely releases the gas.
helping plox.
