Answer 1

Hi there! :)

Both are compounds.

$CO_{2}$ contains 1 carbon (C) atom and 2 oxygen (O)  atoms.

It contains two different elements, so it is a COMPOUND.

$Na_{2} O$ is an IONIC compound with elements Sodium (Na) and Oxygen (O), which are different elements. Therefore, it is also a COMPOUND.
