How would a balloon filled with carbon dioxide look?

Question

compared to a balloon filled with air?

Answer 1

Like it does when a person blows it up!

We breathe out CO2. I agree with mr. chemist lol they all look the same helium is the one that with go towards the ceiling and a human inflated one will sink.

Pure air filled balloon?

Answer 2

They would look the same. Does a balloon filled with helium look any different than one filled with air? Also, assuming you blow the balloon up with your breath, that's closer to carbon dioxide than pure air anyway.

Answer 3

There would be no difference in the shape and both gasses are colorless. There would be a difference in density however. An air filled balloon would float to the floor like a feather. CO2 is denser than air, so a ballon filled with this gas would drop to the floor like a ball.
