Complete tangent, but I don’t think superscript numbers are a good choice in chemical notation. You’re trying to use them here to stand-in for subscript numbers, but superscript numbers have a meaning in chemistry as well. They denote ions.
So, I think CO2 is more accurate than CO², since it could be confused as carbon monoxide with some sort of ion of charge 2 (unclear of positive or negative).

That’s a good point. My phone keyboard has the superscript so I used that without thinking too much
