2. sodium reacts with oxygen to form sodium oxide and has the following balanced chemical equation: 4 na + o2 --> 2 na2o. when you have 30 g of na how many moles of na2o are produced?

0.65mol of Na2O will be produced

Explanation:Please see attachment for explanation

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.
