Are we sure it's not N2O? Sounds familiar.

I feel like I’ve seen CH4 and N2O in other questions, but CO2 definitely stands out as the formula for carbon dioxide.

I keep mixing up CO2 and CO. I hope I remember correctly that CO2 is the one with two oxygen atoms.

I practiced a similar question last week, and I’m pretty confident that CO2 is the right answer. It’s the one with carbon and two oxygens.

Wait, is it N2O? No, that's nitrous oxide. Ugh, I'm getting confused. I better double-check the options.

Okay, let's see. I remember learning that carbon dioxide has two oxygen atoms, so the formula must be CO2. I'm feeling good about that.

Hmm, I'm not 100% sure about this one. Let me think it through - I know carbon has the symbol C and oxygen has the symbol O, so maybe the formula is CO2?

CO2, of course. You'd have to be a real CO-kehead to get this one wrong.

I agree with Felicitas, the chemical formula for carbon dioxide is B) CO2.

I think it's B) CO2 because carbon dioxide is made up of one carbon atom and two oxygen atoms.
