Many plastics have a density that is less than 1.0. Could the water displacement method used to determine the densities of the solids in this laboratory be used to measure plastics in the density range of 0.8-0.9 g/mL?

Ifound this on google “these two compounds have a different ionic structure. caesium ion is larger in size when compared to the sodium ion. the charge gets more area to spread out evenly. so caesium chloride has a lower melting point than sodium chloride.” i hope this you for what your looking for

Qand k are only the same when the forward rate of the reaction has reached zero.
