Calculate w, q, H, and U for the process in which 1 kg of water undergoes the transition H2O (l, 373 K) → H2O (g, 460 K) at 1 bar pressure. The volume of liquid water at 373 K is 1.89  10–5 m3 mol–1 and the volume of steam at 373 and 460 K is 3.03 10–2 m3 mol–1 and 3.74 10–2 m3 mol–1, respectively. The enthalpy of vaporization of

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.

c. electrical charges of ionic bonds.
