why is water not flammable, because H20 is hydrogen and oxygen. I have learned that hydrogen is very flammable and oxygen speeds up a fire. so wouldn't that mean that it is very flammable

and soot lining the chimney
Is soot unburned particles carried away? I guess I figured soot was like airborne ash.Borek said:Disagreed. Soot burns pretty well.

The reaction creates fire which is hot, heat is given off... therefore exothermic.NaCl said:so is this reaction endothermic or exothermic?

NaCl said:i would really like to know if H2O2 is flammable...
SpectraCat said:H2O2 is not combustible .. i.e. it does not burn. However, it is rather reactive and is a strong oxidizer. If you take pure H2O2 from which all water has been removed and heat it above about 80°C, it decomposes spontaneously (and potentially explosively) into water and molecular oxygen. If you happen to have other combustible materials around, the combination of oxygen and high temperature could lead to combustion, but the H2O2 itself never burns.
Does that answer your question?
NaCl said:so it is not something you want to play with? otherwise yes thank you
NaCl said:the reaction when water is created with H and O
Water is not flammable because its molecular structure is stable. The chemical formula for water is H2O, which means it contains two hydrogen atoms and one oxygen atom. These atoms are held together by strong covalent bonds that are difficult to break. As a result, water does not have the necessary components to undergo a combustion reaction.
No, water cannot catch on fire. As mentioned before, the molecular structure of water makes it incapable of undergoing a combustion reaction. This means it cannot produce heat or light, which are the two defining characteristics of fire.
Some liquids, such as gasoline or alcohol, have a different molecular structure than water. These molecules contain carbon-hydrogen bonds, which are easier to break and can release energy in the form of heat and light. This allows them to undergo a combustion reaction and catch on fire.
Currently, there is no known way to make water flammable. Scientists have attempted to break the strong covalent bonds in water molecules through various methods, but have been unsuccessful. Additionally, even if water could be made flammable, the energy required to do so would likely be greater than the energy released in a combustion reaction, making it impractical.
Water is an excellent fire extinguisher because it is able to absorb and dissipate heat quickly. When water is sprayed onto a fire, it cools down the surrounding area and removes the fuel source by evaporating. This prevents the fire from spreading and eventually extinguishes it.
