Answer 2

It looks like you've provided a series of chemical equations. These equations represent chemical reactions. Here's a brief explanation of each reaction:

1. 2NH₄ + O₂ → CO₂ + H₂O: This equation appears to be incorrect as it doesn't balance. The reactants (2NH₄) are not balanced with the products (CO₂ and H₂O). Additionally, it seems like you are trying to react ammonia (NH₄) with oxygen (O₂) to form carbon dioxide (CO₂) and water (H₂O), which is not a balanced chemical equation.

2. Fe + O₂ → Fe₃O₄: This equation represents the reaction between iron (Fe) and oxygen (O₂) to form iron(II,III) oxide, commonly known as magnetite (Fe₃O₄). The equation is balanced.

3. N₂ + O₂ → NO: This equation represents the formation of nitrogen monoxide (NO) by the reaction of nitrogen gas (N₂) with oxygen gas (O₂). The equation is balanced.
