I Review I Constants I Periodic Table When a chemical reaction occurs, atoms rearrange to form new compounds, but no new atoms are created nor are any destroyed. This concept is called conservation of Part A mass. Mass conservation can be seen in a balanced chemical equation, where the numbers of each kind of atom are the same on both sides of the reaction arrow. The figure (Figure 1) shows the reaction of...

Course Home <Chapter 20 Homework Balancing Redox Equations: Half-reaction Method Review Constants Periodic Table In addition to mass balance, exidation reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods: the hall reaction method or the oxidation number method. The hall reaction method balances the electrons lost in the odation all reaction with the electrons gained in the...
