Nitrogenous base: A molecule that contains nitrogen and has the chemical properties of a base. The nitrogenous bases in DNA are adenine (A), guanine (G), thymine (T), and cytosine (C). The nitrogenous bases in RNA are the same, with one exception: adenine (A), guanine (G), uracil (U), and cytosine (C).
option c) triple.
Nitrogen forms 3 covalent bonds ,dear.
hope you'll mark me as brainiest
As, its valence electrons are 5, so if they share 3 each will be (3+3+2),(3+3+2)
bcoz ethyyalpy is more reactive
Nitrogen fixing plants don't pull nitrogen from the air on their own. They actually need help from a common bacteria called Rhizobium. The bacteria infects legume plants such as peas and beans and uses the plant to help it draw nitrogen from the air
here is your answer and hope so it may help you.....!
Hey there !
Alright, so let’s first calculate the oxidation number for Nitrogen in the three compounds.1) Magnesium Nitride => Mg₃N₂
Let the oxidation state of N be ‘x’
Since Mg belongs to the second group, it’s oxidation state is +2. So,
2x + 3(2)= 0
=> x = -32) Ammonia => NH₃
Let the oxidation state of N be ‘y’. The oxidation state of H is +1. So,
y + 3(1) = 0
=> y = -33) Dinitrogen trioxide => N₂O₃
Let the oxidation state of N be ‘z’ here. The oxidation state of O is -2. So,
2z + 3(-2) = 0
=> z = 3So here, the oxidation number of N is found to be +3 only in Dintrogen trioxide. Hence, the third compound is the right answer.
Hope this helps ya ✌️

Other impurities are nitrogen and sulphur that are chemically reduced during coalification to the gases ammonia (NH4) and hydrogen sulphide (H2S), which become trapped within the coal. However, most sulphur is present as the mineral pyrite (FeS2), which may account for up to a few per cent of the coal volume.
PLEASE GIVE ME
mg and n I think this is the answer
nitrogen cycle and sorry I don't know about fixtion
