Carbon monoxide...

[PtCatalyst]

... is CO, not CO2. And definitely not C02 Amazon.

I didn't want to derail any of the threads about the importance of CO alarms but really, a company like Amazon should know what they're talking about. Well, they should now as I have just emailed them about it. I am looking forward to their reply!

Yup. You're right.

carbon MON oxide: the clue is in the name.

CO2 is carbon dioxide isn't it? So you are right.

I have a CSE in Chemistry, grade 3, so I must also be right.

(CSE were exams in the olden days, people).

CO is carbon monoxide,
CO2 iscarbon dioxide.
