Water is the compound. Iodine and calcium are elements, and air is a mixture
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).
Answer: An isotonic solution is a solution in which the amount of dissolved material is equal both inside and outside of the cell. Water still flows in both directions, but an equal amount enters and leaves the cell.
