Title: Water is 88.88 percent oxygen by mass. Oxygen is exactly what a fire needs to gr Post by: einsteindude on Nov 29, 2014 Water is 88.88 percent oxygen by mass. Oxygen is exactly what a fire needs to grow brighter and stronger. So why doesn't a fire grow brighter and stronger when water is added to it?
A) Oxygen in water is already "reduced" from the hydrogen atoms, so this oxygen atom no longer has a great attraction for additional electrons. B) The oxygen is chemically bound to hydrogen atoms. C) Oxygen in water is completely different from oxygen O2, which is what is required for combustion. D) all of the above Title: Re: Water is 88.88 percent oxygen by mass.

Energy is required to convert water into hydrogen and oxygen. It would only make the fire brighter if the resulting oxide was more stable than water |
