Answer 1

N2O2 is the dimer of NO, nitric oxide. It's formed when NO is liquified or frozen. See: http://www.c-f-c.com/supportdocs/nitrogen_oxi.htm
Both NO and N2O2 describe actual molecules. Sodium chloride does not contain any molecules. Rather, it consists of Na+ and Cl- ions in a crystal lattice. All of the Na+ ions are attracted to all the Cl- ions close by, and vice versa. We use the formula "NaCl" just because it expresses the 1 to 1 ratio of Na and Cl.

Answer 2

One thing you need to understand is that there are two types of compounds, ionic and molecular.

Ionic compounds, such as NaCl, are based off of the oxidation states of a particular element. In this case, Na has a oxidation state of 1 and Cl has -1. The subscripts are the lowest number that will make the compound have a total oxidation state of 0. In this example, you need only one of each, (1+(-1)=0), so NaCl works.

Molecular compounds are based on the octet rule (except for hydrogen, which just needs 2). Compounds such as N2O2 bond such that each atom has 8 electrons on its outer shell (these are called valence electrons). The subscripts therefore do not need to be in simplest form.

The reason why N2O2 is acceptable and Na2Cl2 is not is simply because they are two different types of compounds. As an ionic compound, Na2Cl2 should really be 2NaCl. Since N2O2 is molecular, it stays N2O2 (Simplifying the subscripts would make it unable to bond properly)

The name of N2O2 is Dinitrogen dioxide, since prefixes are needed if the subscripts exceed 1 (for the second element, it needs the prefix mono- when there is 1 atom of it).

The name of NaCl (not Na2Cl2) is Sodium Chloride. Ionic compounds do not have the prefixes since the subscripts are based on the oxidation states. Stock Numbers (such as II or III) are placed in parentheses after a particular element name on occasion to specify which oxidation state if it has more than one.

If you don't want to call the second one Sodium Chloride, just say its common name, table salt.

Answer 3

Molecular formulas tell you how many atoms of each element are in a compound, and empirical formulas tell you the simplest or most reduced ratio of elements in a compound. If a compound's molecular formula cannot be reduced any more, then the empirical formula is the same as the molecular formula.

the empirical formula has the smallest whole number for their subscript whereas the molecular formula is the actual number of molecules or atoms in a compound. Some empirical formulas can be the molecular formula, btw.

Answer 6

Because Na and Cl can only have the oxidation states of +1 and -1(Cl can also have positive oxidation numbers, but this does not result in its ionic bond with Na) repectively while N and O have oxidation states of -3/+3/+2/+4/+5 and -1/-2 respectively. This means thats one Na atom can ONLY ionically bond to one Cl atom. While one N atom can bond up to 5 O atoms.

Answer 7

Na2Cl2 is not a proper formula because the ionic form of Na is
Na+ and Cl is Cl- so the proper formula is NaCl. The ionic form of N is N2+ and O is O2-.
Dinitrogen dioxide and sodium chloride (AKA salt)
