How many moles of o2 are needed to create 9 mol of co2 gas

18 molecules of oxygen or o2

Explanation:

Because a carbon dioxide molecule has 2 oxygen molecules and 1 carbon molecule, this would mean that, to make 9 co2 molecules, you would need

18 because 9x2 is 18 molecules of 02

and for carbon molecules its literally 9 because for just 1

co2 it contains 1 carbon molecule

hope this helped

dynamic equilibrium is the answer.

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
