Unformatted text preview: Metals, and Solubility Rules, where reactants are: – solid metal + metal solution – solid metal + acid – solid metal + H2O(l) – Combustion reaction – CxHy + O2 CO2 (g) + H2O (g) – CxHyOz + O2 CO2 (g) + H2O (g) – Balance and identify Decomposition reactions Strong, Weak and Non‐Electrolytes – strong electrolyte: breaks up completely many ions present to conduct electricity – e.g. strong acids & bases, aqueous salts – weak electrolyte: breaks up to small degree only few ions present to conduct electricity – e.g. weak acids & bases, insoluble salts – nonelectrolyte: a molecular compound that forms molecules in water no ions does not conduct electricity Acids and Bases as electrolytes – Know strong acids and strong bases in notes! – All other acids and bases are weak – Know how H2SO4 dissociates in water. page 1 of 3 Chapter 4: Types of Chemical Reactions (Continued) Chemical Equations and (Net) Ionic Equations – Chemical Equation: compounds shown as whole – Complete/Total Ionic Equation: – shows strong electrolytes as separated ions – Spectator Ions: unchanged in chemical reaction – Net Ionic Equation: Shows what substances change in a chemical reaction Guidelines for writing Net Ionic Equations: 1. Complete and balance molecular/chem equation 2. Leave solids, liquids, gases, weak electrolytes a...
