Unformatted text preview: 1 of 2 Chapters 6 & 7: Chemical Reactions Guidelines for writing Net Ionic Equations: 1. Complete and balance molecular/chemical equation 2. Leave solids, liquids, gases, weak electrolytes as compounds, then break up strong electrolytes 3. Cancel spectator ions 4. Simplify coefficients if possible 5. If all reactants and products cancel (all spectator ions) NR Chapter 18: Oxidation‐Reduction (Redox) Reactions • Be able to determine oxidation numbers for all the elements/atoms/ions in a chemical equation. • Use oxidation numbers to determine if a chemical equation represents a redox reaction. • Use oxidation numbers to determine which reactant was oxidized (served as reducing agent) and which reactant was reduced (served as oxidizing agent) • Write half‐reactions to determine the number of electrons transferred. Electrochemical Cells convert the chemical energy of a spontaneous redox reaction into electrical energy (e.g. batteries). Batteries convert stored chem...
