11.5 cm3 of a gaseous hydrocarbon were exploded with excess oxygen and there was a diminution in volume of 34.5 cm3 and on absorption with KOH solution there was a further reduction in volume of 34.5 cm3. What is the molecular formula of the hydrocarbon? (All measurements were made at room temperature and pressure.)

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.
