Experiment 11: Exploring Types of Reactions Single Displacements Balance the single displacement (Redox) reactions below. Report your observations of the reaction in the space provided. Balance the reaction in the full molecular, full ionic, and net ionic forms. The net ionic form represents the essential reaction, ignoring spectators. It is obtained by canceling components that appear on both sides of the full ionic equation. __Mg(s) + 2 HCl(aq) → _H2_+ MO Cla 1 (molecular equation) Macs) + 2H+ + 2 cam)-Mga tag) F2U (a complete ionic equation) _Mg(s) +_2_H'(aq) mga taght H492 (net ionic equation) (oxidation numbers) Describe results: bubbling hot dissolving metal 5. ___Zn(s) + Cu(NO3)2(aq) → Zn(N03) + Cu (molecular equation) Zu(s) + cuptag) + No, caq) + Zn2+ coq) + No, cogit cul complete ionic equation) ___Zn(s) + __ _Cu?*(aq) → Zn?coq)+ Cu(s) (net ionic equation) (oxidation numbers) Describe results: metal turns darker, bubles, lique color to creen 6. __Cu(s) + _2_AgNO3(aq) -(NO3)2+ 2AQ (molecular equation) Curs) tanacaq)+2 No-caq -> Cu2709) 42N10, (aq) + 2Ag Cs)_(complete ionic equation) - Cu(9) + _2_Agʻ(aq) → Cut (g+ 2 A2C5) (net ionic equation) (oxidation numbers) Color change: _copper to green (rusting) Describe results: dissolves Copper d th com B.
