Why does water put out fire even it is made of oxygen that can develop fire and hydrogen that is an explosive gas?

Water is what is known as a compound; that is, a completely different substance made out of different base elements. Compounds often have strange behaviours that their elements do not normally have. For instance, hydrogen sulfide is made of hydrogen gas (an odorless explosive gas) and sulfur (an odorless yellow metal), but in combination it produces something which stinks of rotten eggs!

For water to contribute to a fire, it would have to be broken down into hydrogen and oxygen. This occurs only during electrolysis. This is, however, one of the reasons why you should not throw water onto an electrical fire!

Yes. A mixture of hydrogen and oxygen is highly explosive. Igniting this mixture will form water vapor.


The sodium burns, spilting the water into hydrogen and oxygen. The hydrogen itself then burns with explosive force.


Water is H2O. 2 hydrogen atoms and 1 oxygen atom. Water is not formed when you mix hydrogen and oxygen. An explosive mixture of hydrogen and oxygen is formed. When you burn hydrogen in oxygen, the resulting compound is water. When you boil water the result is steam, or water vapor. Boiling does NOT separate the hydrogen and oxygen. An electrical current is needed to separate the hydrogen and oxygen. CAUTION: Do NOT put salt in the water to speed up the electrolysis of water. It changes the products. instead of hydrogen and oxygen, you get hydrogen, chlorine (gas), and sodium hydroxide. The last two are very poisonous.


No. When making water by burning Hydrogen in Oxygen (a very explosive reaction) is that 2 atoms of Hydrogen and 1 atom of Oxygen join together to form 1 water molecular - H2O.


Because they decompose the water to pure hydrogen and oxygen. The hydrogen is a flammable gas and the oxygen is the oxidizing agent that reacts together in an explosive manner.Caesium


No, liquid oxygen and liquid hydrogen would be rather explosive and in fact has been used for rocket fuel. Alternate answer: No, while water is comprised of Hydrogen and Oxygen, the two usually combine when in a gaseous form.


The bonds between the Hydrogen and Oxygen are strong and no more Oxygen can bond. (Combustion is rapid oxidation).If you separate the Hydrogen from the Oxygen (through pyrolysis for example) the mixture is explosive.A2. The hydrogen has already burnt to make water. It cannot be burnt again.


The chemical compound Water is made of two elements: Hydrogen and Oxygen. To get water you would need to perform a highly explosive chemical reaction. An example of this dangerous reaction occured with old style zeppelins that were filled with Hydrogen. So, the chemical formula of water is H2O and the reaction between Hydrogen and Oxygen is:Hydrogen + Oxygen --> Hydrogen OxideDo not attempt this reaction.


hydrogen + oxygen = HO, hydroxide: hydrogen + oxygen + oxygen = H20, water


Yes, when hydrogen explodes it produces water.


Any flame or electric spark will trigger this explosive reaction!


Hydrogen as water is made of oxygen and hydrogen.



very high temperature is needed to combine hydrogen and oxygen. at that temperature, water exists in gaseous form Oxygen exists as a gas in our atmosphere, because there isn't very much hydrogen in the atmosphere. If the Earth's atmosphere contained a substantial amount of hydrogen mixed with the oxygen, it would be an explosive mixture. Any spark would set it off. They the oxygen and hydrogen would combine to form water, and we would be left without enough oxygen to breathe.


No. Water is a compound made of hydrogen and oxygen. While elemental Oxygen and Hydrogen are gases.


Oxygen is important to water because oxygen is an element in water. Water is made of oxygen and hydrogen. Without oxygen, water would just be hydrogen, not water!


the compound water made up of hydrogen and oxygen. hydrogen and oxygen both are gas. but the compound water is liquid


Yes, water is comprised of Hydrogen and Oxygen, H2O


By reacting it with oxygen; both the hydrogen and the oxygen are converted into water.


No. Hydrogen combines with oxygen to make water.


You can get water from hydrogen if you combine the hydrogen with oxygen atoms.


No. Hydrogen is too dangerous to be where humans live. A spark will generate a glorious explosion. After explosion, the product is water. You need energy to break up the water molecules to form hydrogen and oxygen gases again; the combination of hydrogen and oxygen is also explosive. The energy to break up the water is probably higher than what you can get from burning hydrogen with oxygen -- I did not do a calculation, but if it is untrue, then we should have been breaking up water molecules and not worry about rising gasoline price. So, recycling hydrogen is possible but impractical.


The explosive force is the reaction of potassium with water liberating hydrogen.


Hydrogen plus oxygen creates water


Yes. Ice is solid water. Water is a compound of hydrogen and oxygen.
