Nah, it's just that you're being pedantic (or suck at reading comprehension).
"I feel that liquid water and gaseous water have a significantly different chemical formula."
You feel that way for no apparent reason. Pedantically, the reason could be "because you are lying" or "because you are dumb." Practically, we both know you might mean to say, "Well, chemically they are the same, but one is less dense."
