Worksheet 4 Single Replacement Reactions ACTIVITY SERIES REFERENCE CHART In general a metal can displace any of the metals which are lower in the reactivity series Same rule applies for Halogens Metals from Li to Na will replace H from acid and water Metals from Mg to Pb will replace H from acids only ANSWER KEY Ag KNO3 NR Zn 2AgNO3 2Ag Zn NO3 2
A single replacement reaction sometimes called a single displacement reaction is a reaction in which one element is substituted for another element in a compound The starting materials are always pure elements such as a pure zinc metal or hydrogen gas plus an aqueous compound Single Replacement Reaction Worksheet For each reaction use the activity series to complete the reaction If no reaction will occur write no reaction Make sure you balance your final answer Ag KNO3 Zn AgNO3 Cl2 KI Cu FeSO4 Fe Pb NO3 2 Cu Al2 SO4 3 Al Pb NO3 2 Cl2 NaI Fe AgC2H3O2 Al CuCl2

A single replacement reaction is a reaction in which one element replaces a similar element in a compound The general form of a single replacement also called single displacement reaction is A BC AC B A BC AC B In this general reaction element A A is a metal and replaces element B B also a metal in the compound A single replacement reaction is a chemical reaction in which one element is substituted for another element in a compound generating a new element and a new compound as products Presented below 2HCl aq Zn s ZnCl2 aq H2 g 2 HCl aq Zn s ZnCl 2 aq H 2 g is an example of a single replacement reaction
REACTION If the reaction occurs WRITE THE CORRECT FORMULAS for the reactants and products Remember the following elements are diatomic H2 N2 O2 F2 Cl2 Br2 I2 Use the chart of polyatomic ions and transition metals if necessary BALANCE the equation 1 and 5 are done already as examples Ni CuCl2 Cu NiCl2 Predict the products and balance the following single replacement reactions If no reaction occurs write N R For transition metals use the following charges Iron Fe3 Mercury Hg2 Lead Pb4 Copper Cu1 Gold Au3 Fe CuCl2 Hg Sn SO4 2 Ba Ni3 PO4 2 Pb Au NO3 3 Li HOH K AgCl Ca NaOH
