Hydrogen being a highly inflammable gas and oxygen being a supporter of combustion, yet water which is compound made up of hydrogen and oxygen is used to extinguish fire? Why?
Answers
Water does contain Hydrogen and Oxygen, but it is a compound of two formed by a chemical reaction. Being a chemical compound, water doesn't have property of either Hydrogen or Oxygen. This is because when two or more element combine chemically, the reaction elements. Lose their respective properties and resultant product usually has properties totally different from those of the reacting elements. That is why the properties of water are quite different from those of hydrogen and oxygen.
Water is neither combustible nor support combustion. But it can absorb large amount of heat and can cool hot things effectively.
In order to burn, a substance must reach it's ignition temperature. When water is poured over burning fire ( except an electrical or oil fire), it cools the burning object below it's ignition temperature and puts out the fire.

Answer:
Concept:
The chemical element hydrogen has the symbol H and the atomic number 1. Hydrogen is the lightest element. Hydrogen is a gas made of two atoms with the formula H2 under normal conditions. It's colourless, odourless, tasteless, non-toxic, and extremely flammable. Hydrogen is the most abundant chemical element in the universe, accounting for around 75% of all ordinary stuff. The Sun, for example, is mostly made up of hydrogen in its plasma state. The large bulk of hydrogen on the earth is present in molecular forms such as water and organic compounds. Each atom of the most common hydrogen isotope has one proton, one electron, and no neutrons.
Given:
Despite the fact that hydrogen is a highly flammable gas and oxygen promotes burning, water, a mixture of hydrogen and oxygen, is used to put out fires? Why?
Find:
Despite the fact that hydrogen is a highly flammable gas and oxygen promotes combustion, water, a combination made composed of hydrogen and oxygen, is used to extinguish fire? Why?
Answeer:
Compound qualities differ from those of its individual constituents. Although its fundamental constituents do not have this virtue, water, which is a composite of oxygen and hydrogen, has the ability to extinguish fire. It's due to the fact that water is a compound. Although water is not flammable, the constituent elements hydrogen and oxygen have distinct characteristics.
Despite the fact fact hydrogen is an extremely combustible gas and oxygen stimulates combustion, fires are extinguished with water, a mixture of hydrogen and oxygen.
