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
