Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

Single displacement reactions occur when one more active element kicks out or displaces another less active element in a compound (i.e. Zn (s) + CuSO4 (aq) ZnSO4 (aq) + Cu (s)). Double displacement are similar to single displacement reactions however two elements are displaced instead (they switch compounds‚ observe: KCl (aq) + AgNO3 (aq) AgCl (s) + KNO3 (aq)). A neutralization reaction double displacement reaction that occurs between an acid and base when they are combined (i.e. H2SO4 (aq) + 2NaOH

Lab: Flame Test Purpose: to determine the ID of 2 unknown substances Background Information: Every atom consists of a nucleus with tiny electrons whizzing around it. The further away from the nucleus they are‚ the more energy the electrons have. If a metal atom is heated‚ the electrons get enough energy to jump higher away from the nucleus‚ they become “excited”. When they fall back closer to the nucleus (back to their ground state)‚ they give off this extra energy as light. Why is the
