Assuming non-ideal behavior, a 2.0 mol sample of CO₂ in a 7.30 L container at 200.0 K has a pressure of 4.50 atm. If a = 3.59 L²･atm/mol² and b = 0.0427 L/mol for CO₂, according to the van der Waals equation what is the difference in pressure (in atm) between ideal and non-ideal conditions for CO₂?

im pretty sure its b

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.
