hydrogen is a combustible substance and oxygen is a supporter of combustion. but water extinguishes fire. how is that?

In summary, hydrogen is a combustible substance, oxygen supports combustion, and water is the waste product of this combustion process. Water is not like an ash, as it is produced during combustion. Additionally, being a combustion product does not make something immune to further combustion.

Water is the waste product of the combustion you are describing. It has already been burned.

Uh, yeah. That pretty much covers it.
Water is the "ash" left over from burning hydrogen.

Varsha: Please look up the definition of a "compound" in your chemistry text.varsha said:hydrogen is a combustible substance and oxygen is a supporter of combustion. but water extinguishes fire. how is that?
To others: Something being a combustion product does not mean the thing is immune to further combustion (eg: CO, aldehydes), and that's besides the point here. Furthermore, water is most certainly nothing like an ash. An ash is the uncombusted residue; water is a combustion product.

FAQ: Hydrogen-Oxygen-Water: Fire Extinguisher?
What is a hydrogen-oxygen-water fire extinguisher?
A hydrogen-oxygen-water fire extinguisher is a type of fire extinguisher that uses a combination of hydrogen gas, oxygen gas, and water to put out fires. It is also known as an H2O2 fire extinguisher or a water mist fire extinguisher.
How does a hydrogen-oxygen-water fire extinguisher work?
The hydrogen-oxygen-water fire extinguisher works by releasing a fine mist of hydrogen gas, oxygen gas, and water onto the fire. The oxygen molecules help to suffocate the fire, while the water molecules absorb the heat and cool down the fire. The hydrogen gas also helps to reduce the concentration of oxygen, making it harder for the fire to continue burning.
What types of fires can a hydrogen-oxygen-water fire extinguisher be used for?
A hydrogen-oxygen-water fire extinguisher is suitable for use on Class A, B, and C fires. Class A fires involve ordinary combustible materials such as wood, paper, and cloth. Class B fires involve flammable liquids such as gasoline and oil. Class C fires involve electrical equipment.
Are there any safety concerns with using a hydrogen-oxygen-water fire extinguisher?
While hydrogen-oxygen-water fire extinguishers are generally safe to use, there are a few precautions to keep in mind. The hydrogen gas used in these extinguishers is highly flammable, so they should not be used near open flames or other sources of ignition. Additionally, the mist released by the extinguisher may cause mild irritation to the eyes and skin, so it is important to wear protective gear when using it.
How effective is a hydrogen-oxygen-water fire extinguisher?
A hydrogen-oxygen-water fire extinguisher can be very effective in putting out small fires. However, it may not be as effective as other types of fire extinguishers for larger or more intense fires. It is important to use the extinguisher properly and to have it regularly inspected and maintained to ensure its effectiveness in case of an emergency.
