what is nitrogen fixing

Nitrogen Fixing Organisms - Some bacteria are known to fix the atmospheric nitrogen for their own biological activity. This natural phenomena is commercially utilized to increase the nutrient supply to crops. There are two types of nitrogen fix..

>The nitric oxide so formed then reacts with more oxygen to form nitrogen dioxide. Nitrogen dioxide so formed, gets washed down by rain and forms nitrates and nitrites in the soil. Plants absorb these of nitrates and nitrites from the soil and convert them into plant proteins. A..

This is the next step in photography. During developing some silver bromide will be unreacted and that will be removed in this process. So, the removal of unchanged silver bromide is called as fixing. The film is immersed in sodium thio-sulphate solution to remove AgBr as complex ion. Af..

: Rhizobium, a nitrogen fixing bacteria present in the roots of leguminous plants, fixes atmospheric nitrogen to the soil. Azotobacter and Clostridium are other free-living nitrogen fixing bacteria. Physical fixation When nitrogen..

The nitrogen cycle is complex as it depends on the activities of various bacteria. Nitrate in the soil is built up by plants into protein which is then passed on to animals, which eat the plants. The nitrogen from the protein is returned to the environment as ammonia (ammonifica..

In 1772 Daniel Rutherford discovered Nitrogen. Nitrogen is the first member of group 15 of the periodic table. Nitrogen exists as a diatomic molecule (N 2 ) with a triple bond between the nitrogen atoms (NN). So nitrogen gas is a..

It may be noted that lithium reacts with N 2 to form lithium nitride but sodium does not form sodium nitride...

Introduction - Functional groups containing nitrogen are present in a variety of naturally occurring and man made organic compounds. These functional groups impart physico- chemical characteristics to these molecules. These groups are responsible for their unique chemical reactivity patte..
