Molecular Equations
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A molecular equation writes every reactant and product as a complete neutral formula, not as separated dissolved ions.
Show
AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq) is a molecular equation, written entirely in intact compound formulas.
Watch for
A molecular equation is a bookkeeping convenience, not a claim that dissolved NaCl exists as intact NaCl units.
