Molecular Equations

The idea
A molecular equation writes every reactant and product as a complete neutral formula, not as separated dissolved ions.
In practice
AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq) is a molecular equation, written entirely in intact compound formulas.
Where people slip
A molecular equation is a bookkeeping convenience, not a claim that dissolved NaCl exists as intact NaCl units.
