1) Look up the specific heat values for the Alkaline Earth Metals: Be, Mg, Ca, Sr, Ba, Ra. One website that has this info is ptable. com. The units for specific heat on that website are:
J/kg K

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.
