1__ Zn + ___ CuSO4 __ Cu + __ ZnSO4 Unit 3 Chemical Reactions 3.4 How do we use the Activity Series Table to predict if a reaction will take place?February 8, 2010Do Now: Balance equations if needed. Then, indicate whether the reaction is synthesis, decomposition, single or double replacement.AIM: How can you predict if a reaction takes place using the activity series?__ Zn + ___ CuSO4 __ Cu + __ ZnSO4__ ZnCl2 + __ KOH __ Zn(OH)2 + __ KClJ(Single Replacement)(Double Replacement)
2ACTIVITY SERIES AND SINGLE REPLACEMENT REACTIONS USE Table J,Activity Series in the Reference Table
3HOW TO USE TABLE J? Zn + Cu(NO3)2 Cu + Zn(NO3)2 Type of reaction: Single Replacement
4Zn + Cu(NO3)2 Cu + Zn(NO3)2 Zn Cu Zn is a metal Zn is above Cu FIRST COLUMN OF TABLE JIndicate the single element in the reactants in the reaction2. Indicate the first element in the reactants that is bondedto other elements3. If the single element in a single replacement reaction is a metal, look at 1st column of table J.4. REACTION OR NO REACTION?If the single metal is listed above the metal in the compound, the reaction will take place.ZnCuZn is ametalZn isaboveCu
5EXPLANATION Zn + Cu(NO3)2 Cu + Zn(NO3)2 = REACTION WHY? Zn is above Cu on the table.Therefore, Zn will react with a compoundof copper such as Cu(NO3)2and displace/replace Cu
6NOTE Cu + Zn(NO3)2 will result in…. no reaction WHY is there no reaction?Cu is below Zn, it will not reactwith compounds of Zn
7LET’S TRY SOME 1) Pb + AgNO3 Ag + Pb(NO3)2 ___________________ 2) Ni + ZnSO4 NiSO4 + Zn ___________________reactionBecause Ag is below Pb on Table Jno reactionBecause ZN is above Ni on Table J
8What’s Up with Hydrogen hanging On the metals’ side?
9WHAT’S UP WITH HYDROGEN HANGING ON THE METAL’S SIDE? One element that is in this column that is not a metal is hydrogen.All metals above hydrogen will react and displace hydrogenRESULT hydrogen gas is formed
10LET’S TRY SOME Mg + 2HCl H2 + MgCl2 = REACTION WHY? Mg is above H on the table.Therefore, Mg will react witha compound of hydrogensuch as HCl anddisplace/replace H
11LET’S TRY SOME Ca + H2O Ca(OH)2 + H2 ________________ 2) Cu + H2O Cu(OH)2 + H ________________No reactionBecause Ca is above H on Table JreactionBecause Cu is below H on Table J
13WHEN TO USE IT?If the single element in a single replacement reaction is a non-metal (specifically a halogen), look at second column of table J.A nonmetal will replace a less active nonmetal in a compound (the one that is higher up will react with the one that is lower)
14F2 + 2NaCl Cl2 + 2NaFWhat is the most reactive nonmetal according to the table? _____________Fluorine will react with anything below it and displace it.FLUORINEREACTION WILL HAPPENREVERSE:NO, because chlorine is below fluorine on thelist, it will not replace fluorine in a compound.Cl2 + NaF NO REACTION
15Complete the Independent Practice -IP will be collected at the end of class!!!WORK ON UNIT 1 IN THE HOMEOWORK PACKETMake up LABS!! Come see me if you are missing anyWork on 2.3 Independent Practice from yesterday…..
