Consider the following intermediate chemical equations.


2 equations. First: upper C (s) plus one half upper O subscript 2 (g) right arrow upper C upper O (g). Second: upper C upper O (g) plus one half upper O subscript 2 (g) right arrow upper C upper O subscript 2 (g).


How will oxygen appear in the final chemical equation?

Upper O subscript 2 (g). as a product

Upper O subscript 2 (g). as a reactant

O(g) as a product

2O(g) as a reactant
