substances having more quantity of oxygen when heated liberate oxygen

The reaction is immediate and one can observe bubbles of oxygen gas liberated in the flask. As more and more hydrogen peroxide is added more oxygen is formed. The oxygen produced is collected in an inverted glass cylinder by the downward displacement of water..

Small quantity of oxygen is required for optimum photosynthetic electron transpor..

In the dormant condition the seeds respiratory rate is very low and so oxygen is required in very small quantities. But for germination, oxygen is needed in large quantities. The seeds obtain this oxygen from the air contained in the soil. Seeds sow..

Oxygen - Oxygen is very essential for the existence of human life on Earth. It is the most abundant element on the surface of the Earth. In a free state, it is present in the Earth's atmosphere to an extent of about 21% by volume, (23.15% by mass) In the combined form, it consti..

Magnesium adds on to oxygen to become magnesium oxide. Removal of Hydrogen Hydrogen is removed from hydroiodic acid to liberate free iodine. Reduction is a reaction in which oxygen is removed from a substance or hydrogen is added to a substance..

Two scientists, Carl Scheele of Sweden and Joseph Priestly of England working independently, discovered oxygen. They published their discovery in 1777. Scheele obtained oxygen by heating potassium nitrate and mercuric oxide and called it "Fire Air". Priestley called i..

When Potassium chlorate is heated strongly it decomposes to give oxygen. But if a catalyst like manganese dioxide is mixed with it, oxygen is liberated at much lower temperature, in much shorter time. Potassium chlorate and manganese dioxide are mixed i..

Oxygen is another essential element for living organisms. It is present in large quantities (20.95% v/v) in the atmosphere and is also seen in bound state in water and as oxides and carbonates in rock..
