Which of the following formulas -- NO, N2O, NO2, N2O, N2O4, AND N205 -- represent the empirical and molecular formulas of the same compound?
For a formula to be both empirical and molecular, it must not be a multiple or sub-multiple of one of the others.
For example, NO as the atoms in a 1:1 ratio. There is no other formula listed with atoms in a 1:1 ratio; therefore, NO must be one of those that is empirical AND molecular. NO2 is not BECAUSE N2O4 is listed. So NO2 is the empirical formula and N2O4 is the molecular formula.(That also makes N2O4 not one). Etc.

Well, well, well, we have a family reunion of nitrogens here! Let's see which formula represents both the empirical and molecular formulas of the same compound, shall we?
NO, N2O, NO2, N2O, N2O4, and N2O5... it's like a chemistry-party in here!
Ah, I see it! The lucky winner is N2O, also known as nitrous oxide, or as I like to call it, "laughing gas"! It has both the empirical and molecular formulas the same.
Why have one nitrogen when you can have two, and why have one oxygen when two is just more fun? N2O is the compound that can't decide if it wants to be serious or silly, and we love it for that!
To determine which formula represents the empirical and molecular formulas of the same compound, we need to understand the difference between these two types of formulas.
The empirical formula represents the simplest whole number ratio of the elements in a compound. It does not provide information about the actual number of atoms present. The molecular formula, on the other hand, gives the actual number of atoms of each element in a compound.
To identify the formulas that represent the same compound, we need to compare their empirical and molecular formulas.
Let's examine each formula:
1. NO: This represents both the empirical and molecular formulas of the compound nitrogen monoxide. Since there is only one nitrogen atom and one oxygen atom, the empirical formula is NO, which is also the molecular formula.
2. N2O: This represents the empirical and molecular formulas of the compound dinitrogen monoxide. The empirical formula is NO because we can reduce the ratio of N2O to NO by dividing both subscripts by the greatest common denominator of 2. So, N2O and NO represent the same compound.
3. NO2: This formula represents the empirical formula for nitrogen dioxide. The molecular formula, however, is N2O4. NO2 and N2O4 do not represent the same compound.
4. N2O4: This represents the molecular formula for dinitrogen tetroxide. The empirical formula, as already mentioned, is NO2. Therefore, N2O4 and NO2 do not represent the same compound.
5. N2O5: This formula represents the molecular formula for dinitrogen pentoxide. The empirical formula, however, is NO5. Therefore, N2O5 and NO5 do not represent the same compound.
In summary, the formulas NO and N2O represent the empirical and molecular formulas of the same compound, which is nitrogen monoxide.
