N2o major species present when dissolved in water

The major species present upon dissolution will be water and N₂O because N₂O is soluble in water.

Explanation:

By "major species," it means, "what type are most of the atoms gift in."

N2O is an ionic compound consisting of N2 + and O - ions. it's gift as molecules within the gas section, however once value-added to water, the ions dissociate (this is true of all robust acids). that the major species gift in answer are H + (which is typically aforementioned to react with water to make H3O + or different complexes with water, thus place this if you want).

The major species present upon dissolution will be water and N₂O because N₂O is soluble in water.
