When Lightning Strikes, Nitrogen Molecules, N₂, and Oxygen Molecules, O₂

question 172

Multiple Choice

When lightning strikes, nitrogen molecules, N₂, and oxygen molecules, O₂, in the air react to form nitrates, NO₃^-, which come down in the rain to help fertilize the soil. Is this this an example of oxidation or reduction?

• A)The formation of nitrates is an example of oxidation.
• B)The formation of nitrates is an example of reduction.
• C)Both. The nitrogen is oxidized as it reacts with the oxygen while the oxygen is reduced.
• D)Neither. Although the bonds of both the N₂ and O₂ molecules are broken to form the NO₃^-, neither oxidation nor reduction occurs.
