If Nitrogen would have properties like Fluorine(and higher reactivity than Oxygen), it could have displaced Oxygen from Water to form a compound Hydrogen Nitride
lightning forces nitrogen and oxygen to combine with the water of rain and carries the nitrogen down into soil
Acid Rain
Nitric oxide (NO) is very toxic by inhalation.
Radium react with water, chlorine, fluorine, iodine, bromine, nitrogen, oxygen, etc.
The energy of the lightening causes nitrogen molecules and water molecules to combine. This creates ammonia and nitrates. These forms can be absorbed by plants.
The water will turn into whatever color the food dye.
Sulfuric acid and nitric acid are obtained.
The air is already 78% nitrogen, so nitrogen doesn't pollute air. That being said, the nitrogen in air reacts under high heat and/or pressure such as an engine or combustion process to make nitrogen oxides which are toxic or can combine with water to make acid rain, or combine with reactive hydrocarbons in the presence of ultraviolet light to make photochemical smog.
It depends on how much water, how hot it is, and how much liquid nitrogen there is. The water will initially cause the liquid nitrogen to boil; if there's enough water and it's hot enough, it may make the nitrogen boil explosively. However, if there's enough nitrogen, it will eventually freeze the water.
Sulfur oxides combine with water to produce sulfuric acid but not nitro acids. Nitro acids are a product of nitrogen oxides reacting with water.
