Wat is considered a compound of hydrogen and oxygen and not a mixture because hydrogen and oxygen have gone through a chemical process to form the compound h2O. A mixture can generally be easily separated whereas a compound must undergo another chemical process to separate its elements. Therefore to separate oxygen and hydrogen from water a chemical process is necessary.
Water is classified as a compound because it consists of hydrogen and oxygen atoms that are chemically bonded in a specific ratio (H₂O). Unlike mixtures, where substances retain their individual properties, water has unique properties resulting from its bonded structure. Additionally, separating the elements of water requires a chemical process, not a physical one.
