Asolid is to be comminuted as to increase its solubility by 10%, that is, s/s0 is to become 1.10. what must be the final particle size, assuming that the surface tension of the solid is 100 dynes/cm and the volume per mole is 50 cm3. the temperature is 27°c.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
