<span>FIXATION.In the nitrogen cycle, nitrogen is converted into many chemical forms through biological and physical processes like nitrogen fixation, ammonification, nitrification and denitrification.During ammonification, ammonium ions are released after decomposition of plants.During nitrogen fixation, nitrogen gas is changed to nitrates by nitrogen fixing bacteria in the soil.These are used by vegetation.</span>
Answer:
A is correct (ur welcome)
Explanation:
Answer is: c. 6.02 x 10^23.
n(N₂) = 1.00 mol; amount of nitrogen molecules.
Na = 6.02·10²³ 1/mol.
Na is Avogadro number or Avogadro constant (the number of particles, in this example nitrogen molecules, that are contained in the amount of substance given by one mole).
N(N₂) = n(N₂) · Na.
N(N₂) = 1.00 mol · 6.02·10²³ 1/mol.
N(N₂) = 6.02·10²³; number of nitrogen molecules.
