What are you asking???? If the formula had no atoms of oxygen then......
The correct answer is carbon dioxide and water vapor
These negative gasses get modified and then remain in the atmosphere without the possibility of leaving, which is why the greenhouse effect occurs.
Methane CH4
ethane C2H6
propane C3H8
Butane C4H10
pentane C5H12
<span>If a neutral atom becomes negatively charged, it has undergone reduction.
Reduction is the process through which a neutral atom gain an electron (thus reducing its oxidation number) and turns into a negative ion (also known as : anion)</span>
The answer would have to be ummm 2
