Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.
If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
Molecular formula of a chemical substance is representative for the composition of this chemical substance.
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
From the percentage composition only, an empirical formula can be derived, but a proper molecular formula can only be assured by adding some information about the molecular weight of the substance concerned.
I dont know thats why im asking >_>
No mobile charged particles are present in sufficient concentration.
Molecular compounds certainly can be formed from semimetals, but not all the compounds of semimetals are molecular.
simple molecular compounds have weak forces of atraction.
Its molecular composition will determine which light wavelengths are absorbed and reflected.
the relationship between prefixes and molecular compounds is that, prefix are used to name molecular compounds.
Molecular compounds contain only non-metals (carbon, hydrogen, phosphorus), while ionic compounds contain at least one metal (zinc, manganese, iron) and at least one non-metal.
When molecular compounds bond, they share electrons.
A chemical reaction alters molecular composition.
Atoms are arranged in molecular compounds in groups.
Correct, molecular Compounds have covalent bond.
Binary molecular compounds are formed from the reaction between two nonmetals. The formulas for binary molecular compounds are written in a similar manner with ionic compounds.
Because there are no compounds that aren't molecules/molecular. The question as posed is nonsense. Rephrase?
Molecular compounds, also known as covalent compounds, have relatively low melting and boiling points. Molecular compounds tend to be soft and flexible.
Molecular compounds tend to have lower melting points.
The rules for naming binary molecular compounds are similar to those for naming ionic compounds. However, the names of molecular compounds include prefixes that indicate the number of atoms in the molecule.
Such compounds in which atoms are held by covalent bonds are termed molecular compounds.Binary means two, so such molecular compounds which have two sort of elements in are possibly termed binary molecular compounds.for example Binary acids are certain molecular compounds in which hydrogen is combined with a second nonmetallic element.Examples: H2O, HF, HCl, HBr, HI
Molecular compounds are typically composed of nonmetals.
Some molecular compounds, such as methyl mercury, contain both metals and nonmetals. Most molecular compounds contain only nonmetals, and all molecular compounds contain at least one nonmetal element.
The most common and simplified method and convention of notating elemental composition and molar quantities of molecular compounds comes through their molecular formula. In water, its formula is H2O indicating it contains a single atom of oxygen and two of hydrogen.
Molecular compounds are composed of atoms of different elements covalently bonded. The smallest particle of a molecular compound is a molecule.
Molecular compounds have low melting and boiling points, and do not conduct electricity.
