chemisttree said:It must be because they assume you know that silver nitrate is used to determine halogens. They also assume the you have no oxygen in the compound and that oxygen is used in excess as a reagent in the C and H determination.
chomool said:is there any restrictions in composition elements of the empirical formula?
An empirical formula in chemistry represents the simplest ratio of elements in a compound. It shows the relative number of atoms of each element in the compound.
The empirical formula is determined by dividing the mass of each element in the compound by its molar mass and then finding the smallest whole number ratio between the elements.
Yes, the empirical formula can be the same as the molecular formula if the compound is made up of elements in their simplest ratio. However, in most cases, the molecular formula is a multiple of the empirical formula.
The empirical formula can provide information about the relative number of each element in a compound, allowing scientists to determine the elements present and their ratios. It can also give insight into the structure and properties of the compound.
The empirical formula is the simplest ratio of elements in a compound, while the molecular formula represents the actual number of each element in a molecule of the compound. The molecular formula can be a multiple of the empirical formula.
