Double Replacement Prediction

This comprehensive guide focuses on double replacement reaction prediction and analysis, providing insights into identifying reactants and predicting products. It emphasizes understanding different reaction types, including redox reactions, and includes practical exercises for students. Key activities involve reviewing notes, predicting outcomes of combustion, decomposition, single replacement, and combination reactions, and even exploring scenarios where no reaction occurs. The guide also features a flowchart assignment to support learning and reinforce the concepts of balancing charges and reactions effectively. ###

RP Mixed 4 Explain what went wrong! • B:2.9.6.6 O:C,R:O • C:1.1.2 not redox • D:2.3.2 O:O,R:Cl • D:2.1.3 O:N,R:H • SR:1.2.2.1 O:Br,R:F • B:2.7.6.6 O:C,R:O • C:1.1.1 not redox • SR:1.1.1.1 O:Zn,R:H • B:2.9.6.8 O:C,R:O • SR:NR • SR:NR • D:2.2.1 O:O,R:Pb • C:NR Explain why some reactions are No Reaction!

  9. Double Replacement Prediction Date

  10. Identification from Reactants • Two compounds • Note if both anions are the same (oxide), then it is probably a combination reaction! • Don’t let me trick ya!!!

  11. Prediction of Products • Switch the anions • Or cations if you prefer • Outsides together and insides together • Like FOIL! 

  12. Iron (III) hydroxide + phosphorous acid • Fe(OH)3 + H3PO3g FePO3 + 3 HOH

  13. DEMO Ammonium nitrate and barium hydroxide • NH4NO3 + Ba(OH)2g NH4OH + Ba(NO3)2

  14. Aluminum sulfide + hydrochloric acid • Al2S3 + 6HCl g 2AlCl3 + 3H2S

  15. DEMO Acetic acid and sodium bicarbonate. • HC2H3O2 + NaHCO3g H2CO3 + NaC2H3O2

  16. Homework Time • Complete reaction prediction I • ID rxn type FIRST • Then LOOK at those notes to help you predict the products. • Balance Charges • Balance the Reaction
