air---pollutants such as pollen and other solid particles and water vapor make air composed of multiple phases therefore it is a heterogeneous mixture pure air--- homogeneous mixture; a solution ink---homogeneous mixture of different dyes; a solution table salt ---compound of sodium and chlorine wood --- compound *wood might be a heterogeneous mixture because it was once living but I don't think it's a compound alcohol-compound of carbon oxygen and hydrogen apple - heterogeneous mixture of vitamins etc milk -heterogeneous mixture plutonium--element water-compound of hydrogen and oxygen but i think there is some mistake in this question , is it India or air India or ink paper .well very confusing yet i have tried to convince u

Diamond is the hardest materail in the world
It is not necessarily any of these, as "pebble" describes a grain size and does not say anything about composition. In most cases, though, a pebble is a mixture.
O stands for oxygen and Ra stands for Radium. So, to answer your question, RaO stands for Radium Oxygen
it is compound solution! Yamaha!
Grain alcohol is a homogeneous mixture because it is composed of alcohol and water, which are completely mixed at the molecular level. It is not an element or compound on its own, but a mixture of different substances.
