Net Ionic Equations and Balancing

The video tutorial explains how to write a balanced net ionic equation for the reaction between iron metal and lead(II) nitrate. It begins with balancing the molecular equation, assigning states to each substance, and then forming the complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation. The tutorial concludes by verifying the balance of charges and atoms in the final equation.
