Rost Lab: Single-Replacement Reactions occur when a more reactive element displaces a less reactive element compound. There is a table on the back of your periodic table labeled "Activity Series". Higher elements are more elements on the table In other words elements higher on the Activity series will replace elements lower in the seri elements will not replace higher elements. The speed and energy of the reaction is directly proportional to the dis two elements on the series. 3. Balance the following equations. a. $\underline {\quad }F_{2}+\underline {\quad }NaCl\rightarrow \underline {\quad }Cl_{2}+\underline {\quad }NaF$ b. $\underline {\quad }Li+\underline {\quad }MgCO_{3}\rightarrow \underline {\quad }Mg+\underline {\quad }Li_{2}CO_{3}$ c. $\underline {\quad }K\quad +\underline {\quad }Al(OH)_{3}\rightarrow \underline {\quad }Al\quad +\underline {\quad }KOH$ d. $\underline {\quad }Br_{2}+\underline {\quad }CaCl_{2}\rightarrow \underline {\quad }Cl_{2}+\underline {\quad }CaBr_{2}$ e. $\underline {\quad }Zn+\underline {\quad }Cu_{3}(PO_{4})2\rightarrow \underline {\quad }Cu+\underline {\quad }Zn_{3}(PO_{4})_{2}$
