Carbon is always present in all organic compounds, but lacking in inorganic compounds. Similarly hydrogen is always present in organic compounds but are missing in inorganic compounds.
The difference between heterogeneous and homogenous mixture is that in homogenous the compound totally dissolves and we cannot determine the compounds as water and sodium chloride ( salt ).and heterogeneous mixture totally describes the compounds present in it. For example : biryani .
