A compound is a chemical substance formed from two or more elements which can be separated into its constituent elements.
Now let's learn what is molecular formula of compounds.
Molecular formula of compounds shows the constituent elements of the compound with their symbols and number of atoms on each element contained in the compound.
We will learn how to represent some compounds in their molecular formula.
Lead carbonate - its molecular formulae is 2PbCO3.Pb(OH)2
Sodium Chloride - its molecular formula is NaCl
Carbon dioxide - CO2
Molecular formulas go one step beyond the empirical formula in that they express not only the correct ratio but the correct number of atoms in the molecule.
