The principal reason for the extremely low solubility of nacl in benzene (c6h6) is the the principal reason for the extremely low solubility of nacl in benzene (c6h6) is the weak solvation of na+ and cl- by c6h6 increased disorder due to mixing of solute and solvent hydrogen bonding in c6h6 strong solvent-solvent interactions strength of the covalent bond in nacl

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
