Explanation:
The given reaction is as follows.
[tex]2H_{2}(g) + O_{2} \rightarrow 2H_{2}O(l)[/tex]
Here two hydrogen molecules combine with one oxygen molecule to result in the formation of two molecules of [tex]H_{2}O[/tex].
This, [tex]H_{2}O[/tex] is known as water. As a water molecule can only be formed by the combination of hydrogen and oxygen atoms.
Thus, we can conclude that the name water describes the product in this reaction.
