Answer:
The correct answer is reduction.
Explanation:
Nitrogen gas reacts with hydrogen gas and get reduced to form ammonia. In this reaction.This is important reaction of atmospheric nitrogen fixation.The reaction is carried out by many nitrogen fixing bacteria such as Azotobacter,Clostridium etc.
N2+3H2+6e- = 2NH3
The reaction N2 + 6e → 2N-3 represents reduction, where nitrogen gains electrons to form N-3 ions.
The reaction N2 + 6e → 2N-3 represents reduction. In this reaction, nitrogen (N2) gains electrons (e) to form N-3 ions. Reduction is a process in which an atom or ion gains electrons, resulting in a decrease in its oxidation state.

Answer : The concentration of (g) in parts per million is, 8 ppm
Explanation : Given,
Mass of oxygen gas (solute) = 0.008 g
Mass of water (solvent) = 1000 g
First we have to calculate the mass of solution.
Mass of solution = Mass of solute + Mass of solvent = 0.008 + 1000 = 1000.008 g
Now we have to calculate the concentration of (g) in parts per million.
ppm : It is defined as the mass of solute present in one million parts by mass of the solution.
Now put all the given values in this expression, we get
Therefore, the concentration of (g) in parts per million is, 8 ppm

The number of moles in the 4.30 g of SiH₄ is 1.338 moles.
The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
To calculate the moles
The molar mass of SiH₄ is 32.12 g
The mass of SiH₄ is 43.0 g
Thus, the number of moles in the 4.30 g of SiH₄ is 1.338 moles.
