A small bubble rises from the bottom of a lake, where the temperature and pressure are 8°C and 6.4 atm, to the water*s surface, where the temperature is 25°C and the
pressure is 1.0 atm. Calculate the final volume (in mL) of the bubble if its initial
volume was 2.1 mL.

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.
