May 8th, 2008 | by Muneeb Akhtar |
Oxygen, or O2, 21 percent of oxygen present in earths atmosphere , oxygen gas supports life and makes combustion possible. The most abundant of all elements on earth is oxygen which exists 85 percent of its oceans and, as a component of most rocks and minerals, 46 percent of its solid crust. In addition, it constitutes 60 percent of the human body.
Physical properties of oxygen gas
*oxygen gas is Colorless, odorless and tasteless gas.
*A little amount of oxygen is soluble in water.
*A specific gravity of 1.105 makes it slightly heavier than air.
*when its cooled oxygen becomes a transparent, pale blue liquid that is slightly heavier than water.
Chemical properties of oxygen gas:
*Oxygen reacts with all elements, except inert gases, to form compounds called oxides.
*The rate of reaction - known as oxidation - varies. For example, magnesium oxidizes very rapidly, igniting spontaneously in air.
*noble metals, such as gold and platinum, oxidize only at very high temperatures.
Oxygen helps in burning and in doing chemical reaction thats why sometime some chemical reaction are uncontrollable and very powerful.
