Answer 2

It seems like you've provided chemical formulas for three different compounds. Here's what each of them represents:

1. Ar(CH4): This notation is a bit unclear. "Ar" typically stands for "argon," which is a noble gas. However, in this context, it's not clear how argon is related to the compound CH4 (methane). CH4 is a simple hydrocarbon consisting of one carbon atom and four hydrogen atoms.

2. Ar(CO2): Similarly, the notation here is unclear. "Ar" usually represents argon, and CO2 represents carbon dioxide, a molecule composed of one carbon atom and two oxygen atoms.

3. Ar(P2O5): Once again, the notation is unclear. "Ar" is usually argon, and P2O5 represents diphosphorus pentoxide, a compound composed of two phosphorus atoms and five oxygen atoms.

If you could provide more context or clarify the notation you're using, I'd be happy to help you further.
