a molecule of water contains hydrogen and oxygen in a 1:8 ratio by mass. This is a statement of _____________
Water contain s hydrogen in the oxidation state +1 and oxygen in the oxidation state −2. It oxidizes chemicals such as hydrides alkali metals and some alkaline earth …
For example water is always composed of a 2:1 ratio of hydrogen to oxygen atoms and ethanol (ethyl alcohol) is always composed of carbon hydrogen and oxygen in a 2:6:1 ratio . However this does not determine the kind of molecule uniquely – …
Since Dalton supposed (incorrectly) that a water molecule consisted of one hydrogen and one oxygen atom this would imply an atomic weight of oxygen equal to eight. However expressing the reaction in terms of gas volumes following Gay-Lussac's law of combining gas volumes two volumes of hydrogen react with one volume of oxygen to produce two volumes of water suggesting (correctly) that the atomic weight of oxygen …
