Give reason paper is not considered as a pure substances​

Answer»

ANSWER:

Remember that paper is made out of trees. Thus, paper is made mostly out of organic compounds: that is carbon, hydrogen and OXYGEN (C, H and O). Paper ALSO contains non organic materials to improve its properties. These may be CHALK (CaCO3) and kaolin clay (Al2Si2O5(OH)4). Titanium oxide (TiO2) is also commonly USED in paper for bleaching it.
