Four students do a density lab. Their four measurements are 6.80 g/mL, 5.90 g/mL, 7.10 g/mL and 6.65 g/mL. The accepted value is 6.60 g/mL. These measurements are

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.
