advantages of using oxygen

Main source of oxygen are the plants which evolve oxygen as a by-product of photosynthesis. It is used chiefly by most of the living organisms in their aerobic respiration except certain anaerobics. Oxygen acts as a limiting factor in the distribution of ani..

Oxygen has varied industrial and scientific uses. Oxygen (or dioxygen) is used in steel making It is also used in oxy-hydrogen and oxy-acetylene welding torches. Oxygen is used as an oxidizer in rocket propellants and in..

To Demonstrate Aerobic Respiration The apparatus shown is called the respiroscope that is used to demonstrate respiration. Few germinating seeds are taken in the bulb of the respirometer. The tube is inserted into a beaker containing mercury. A pellet of KOH is introduced into the set..

Oxygen is transported in a combined state. The haemoglobin pigment (Hb) has an affinity for oxygen. In the lungs, it combines with oxygen and forms HbO 2 , oxyhaemoglobin...

Lower alkenes are mixed with air and passed under pressure over a silver catalyst at 200-400°C. This gives epoxides by adding one atom of oxygen across the double bond. The epoxides so obtained are used in detergents. ethene ..

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..

The energy requirements of metabolic processes are met with to a larger degree by aerobic respiration. Thus the quantity of oxygen available to plants governs their growth ra..

Lithium tarnishes slowly in moist air while dry air has no effect. When heated in air or oxygen at about 200C, it burns with a brilliant white light forming lithium monoxide. ..

Any of the above mentioned methods could be used to prepare oxygen in the laboratory. Mercuric and silver oxides are not used for the preparation of oxygen, as they are very expensiv..
