Answer 3

It looks like you've provided a series of chemical reactions involving various elements reacting with oxygen (O₂). However, the equations you've given are incomplete, and I'm not sure what the products (P) are meant to be in the second equation. Could you please provide more context or clarify the reactions you're referring to? This will help me provide you with accurate information.
