Will the Reaction Occur?

Reactions that ALWAYS Occur Synthesis Decomposition Combustion

Will the Reaction Occur in Single Replacement Reactions? To determine if a reaction occurs, use the Activity Series Chart. If single element is listed higher in chart, the reaction WILL OCCUR! An activity series chart shows which elements are more or less reactive than other elements.

Will the Reaction Occur in Single Replacement Reactions? Example: K + LiCl → Li + KCl Will the Reaction Occur? YES or NO Potassium is BELOW Lithium on the Activity Series Chart. Therefore, the reaction will NOT occur.

Practice Mg + Zn(NO3)2 Ca + LiBr → → Zn + Mg(NO3)2 Ca + MgCl2 → YES Mg + Zn(NO3)2 Ca + LiBr → → Zn + Mg(NO3)2 NO NO • Cu + NaNO3 → Ca + MgCl2 → YES Mg + CaCl2

YES • K + Al(NO3)3 → Practice Ca + CuBr2 → Cu + CaBr2 Al + KNO3 YES • Ba + HgCl2 → Hg + BaCl2 Au + KNO3 → NO

Practice YES Zn + AgNO3 → Ag + Zn(NO3)2 NO H2 + CaF2 →

Will the Reaction Occur in Double Displacement Reactions? To determine if the reaction occurs, use the Solubility Chart. In a Double Displacement Reaction, one product must be soluble & one must be insoluble. The insoluble solid that forms is called the precipitate.

Will the Reaction Occur in Double Displacement Reactions? Example: AgNO3 + KCl → KNO3 + AgCl Using the Solubility Chart: In KNO3, find the ANION (NO3−). Notice (NO3) is under the SOLUBLE heading and it does not have any exceptions. Therefore, KNO3 is the SOLUBLE product. In AgCl, find the ANION (Cl−). Notice (Cl−) is under the SOLUBLE heading, BUT (Cl−) does have an exception when bonded with Ag. Therefore, AgCl is the INSOLUBLE product Will the Reaction Occur? YES or NO

Practice → AgI + Al(NO3)3 AgNO3 + AlI3 + HNO3 Ca(NO3)2 + HCl → CaCl2 precipitate Insoluble → AgI + Soluble Al(NO3)3 YES AgNO3 + AlI3 Soluble + HNO3 NO Ca(NO3)2 + HCl → CaCl2 Soluble LiNO3 Insoluble + Zn3(PO4)2 YES Li3PO4 + Zn(NO3)2 → Insoluble Soluble YES Ba(NO3)2 + CaSO4 → BaSO4 Ca(NO3)2

Practice → CuCl2 + AlBr3 + KBr CuBr2 + AlCl3 + KOH → Ca(OH)2 AlCl3 + Soluble → CuCl2 Soluble + AlBr3 + KBr NO CuBr2 + AlCl3 NO • CaBr2 + KOH → Ca(OH)2 Soluble Insoluble AlCl3 + HgI2 YES AlI3 + HgCl2 →
