Explanation / Answer

We Know that :     Homogeneous mixture is the components inwhich the physical state of all the components should besame.         Air is ahomogeneous mixture in which all the components are in gaseous state.     Hetrogeneous mixture is the components inwhich the physical state of all the components should bedifferent from each other.         Decompositionof CaCO3(s) ------->  CaO(s) + CO2 ( g )       All the components are in thesolid state so the mixture is considered to be Homogeneousmixture.          Brownsugar - Compound ( Pure substance )           Diamond - Element (Pure substance )            Air - Mixture (Homogeneous)            granolacereal - Mixture (Hetrogeneous)
