1.	Classify the following as pure substances or mixtures and separate the pure substance into elements and compounds and divide the mixtures into homogeneous and heterogenous categories: (i) graphite (ii) milk (iii) air (iv) diamond (v) petrol (vi) tap water (vii) distilled water (viii) oxygen (ix) 22 carat gold (x) steel (xi) iron (xii) iodized table salt (xiii) wood (xiv) cloud
Answer» hite = ELEMENT 2. MILK = heterogeneous mixture (colloid) 3.air = homogeneous mixture 4.diamond =element 5. petrol= homogeneous mixture 6. tap water=compound 7. distilled water =compound 8. OXYGEN =element 9. 22 carat gold = homogeneous mixture 10.steel= homogeneous mixture 11.iron = element 12. oxidized table salt = compound 13. WOOD= element 14.cloud= heterogeneous mixture.
