No, NO and NO2 do not have the same empirical formulas. The empirical formula for nitrogen monoxide (NO) is NO while the empirical formula for nitrogen dioxide (NO2) is NO2.
The formula is NO2, One Nitrogen and 2 Oxygen
Yes, NH3 is an empirical formula. An empirical formula represents the simplest whole-number ratio of atoms in a compound. In the case of ammonia (NH3), the ratio of nitrogen to hydrogen is 1:3, making NH3 the empirical formula.
The empirical formula for a compound represents the simplest whole number ratio of atoms present in a molecule. For the molecular formula N2O4, the empirical formula is NO2 because it shows the simplest ratio of nitrogen and oxygen atoms present in the compound.
The empirical formula of carbon dioxide is CO2, which represents the simplest whole-number ratio of the elements present in the compound.
