Is air an element compound?
Air is a mixture of elements and compounds.Why air is a compound?
Air is a mixture, and not a compound because air can be separated into different components such as oxygen, nitrogen, etc. through the process of fractional distillation. Also, air shows all the properties of gases present in it.Is air a compound mixture and element?
Air is nothing but a general name for the mixture of gases like Nitrogen , mixed with Oxygen , water vapor H 2 O ), Argon. , Carbon dioxide. , dust, pollen, and spores. Here Oxygen is an element while water vapor is a compound made with Hydrogen and Oxygen. It means air is a mixture of elements and compounds.- The primary component of air is nitrogen gas. Nitrogen, oxygen, water vapor, argon, and carbon dioxide account for about 99% of the composition of air. Trace gases include neon, methane, helium, krypton, hydrogen, xenon, ozone, and many other elements and compounds.
