To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 2.7-L bulb, then filled it with the gas at 1.90 atm and 29.0 ∘C and weighed it again. The difference in mass was 5.9 g . Identify the gas.

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.
