Net Ionic Equations and Reactions

This video tutorial guides viewers through writing a balanced net ionic equation for the reaction between iron(II) chloride and magnesium. It begins with balancing the molecular equation, assigning states to each substance, and then splitting strong electrolytes into ions to form the complete ionic equation. Spectator ions are identified and removed, leaving the net ionic equation. The tutorial emphasizes the conservation of charge and atoms, ensuring the equation is balanced.
