Luminescent I'm pretty sure :)
I believe body waves can actually reach the core as they follow raypaths refracted by the varying density and modulus of Earths interior.
Hope this helps!
Solvation describes the interaction of solvent with dissolved molecules.
One separation technique to be used is the paper chromatography. This works by separating the components of the mixture through the difference of their concentrations. There is a stationary phase and the mobile phase, which flows through the stationary phase. The components travel at different rates and is usually signified by the colors. If more than one color would appear, that means that the dye is a mixture.
