Consider the following intermediate chemical equations. 2 equations. First; upper C upper H subscript 4 (g) plus 2 upper O subscript 2 (g) right arrow upper C upper O subscript 2 (g) plus 2 upper H subscript 2 upper O (g). Second: 2 upper H subscript 2 upper O (g) right arrow 2 upper H subscript 2 upper O (l).

Which overall chemical equation is obtained by combining these intermediate equations?
