In this VIDEO, Mr. Hatfield provides equations for reactions involving both ionic compounds (like the SrCO3 in the 'Conservation of Mass' Lab) and covalent compounds (like the hydrocarbons in the 'Conversion of Paraffin' Lab).
Then, step by step, Mr. Hatfield balances all of these equations.
Balancing equations is an iterative procedure, sometimes called 'trial and error', and students have to practice the skill of unpacking and balancing equations many times before it will become routine:
