WHAT IS COMPOUND?

= A compound is a substance formed when two or more chemical elements are chemically bonded together. In mixtures, the substances present are not chemically bonded together.The elements in any compound are always present in fixed ratios.

WHY NOT AIR,ALLOY,EMULSION CAN BE COMPOUND?

➨AIR IS NOT COMPOUND BECAUSE: Air can be separated into its constituents such as oxygen, nitrogen etc and thing to remember is AIR is a mixture not a compound.

➨EMULSION is also not compound because,An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) owing to liquid-liquid phase separation.

➨ALLOY An alloy is mixture. In alloy the metals and non-metals do not chemically react with each other and there is just a physical mixture of different element.
