Carbon Monoxide with zinc powder & calcium c

[Northerngirl1965]

First post... I was wondering if heating these two ingredients would be a viable method of carbon monoxide production. Would appreciate feedback. Thanks. I bought sulphuric acid & formic acid but dont know about the setup protocol

you need higher temperature (bad, but I did not found further details) otherwise only CO2 get produced

and CO is flammable, not easy to handle this stuff

Zn + CaCO3 => ZnO + CaO + CO /// under higher temperature

"2 Masseteile Zink und 1 Masseteil Calciumcarbonat mischen"
