Interpretation: To give the empirical and molecular formula for A and B and draw the Lewis structure for A.
Concept introduction:
The reaction of
Empirical formula of a compound is the smallest integer ratio of numbers of each element presented in that compound.
Molecular formula of a compound is integer multiple of empirical formula, the integer is depend upon the mass of empirical formula and the molecular mass of the compound.
Lewis structures are diagrams that represent the
It is also known as Lewis dot structures which represent the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
