III. Predict The Products Part 1 (Single Replacement Rxns)
Recall… 5 Types of Rxns • Synthesis – A + B AB • Decomposition – AB A + B • Combustion – O 2 as a reactant (left side) – Hydrocarbon combustion always produces H 2 O and CO 2 • Single Replacement (Steal Yo Girl) – A + BC AC + B • Double Replacement (Dance Partners) – AB + CD AD + CB
Identify the Type of Reaction • Ca. CO 3 Ca. O + CO 2 Decomposition • Pb + Fe. SO 4 Pb. SO 4 + Fe Single Replacement • C 6 H 12 + 9 O 2 6 CO 2 + 6 H 2 O Combustion • 2 C 5 H 5 + Fe Fe(C 5 H 5)2 Synthesis • 2 Rb. NO 3 + Be. F 2 Be(NO 3)2 + 2 Rb. F DR
A. Single Replacement Rxns A + BC AC + B One atom replaces another atom in a compound Pb + Fe. SO 4 Pb. SO 4+ Fe
A. Single Replacement Rxns Cont. Zn + 2 Ag. NO 3 Zn(NO 3)2 + 2 Ag A metal replaces another metal Mg+ 2 HCl Mg. Cl 2 + H 2 A metal replaces hydrogen Cl 2 + Ca. Br 2 Ca. Cl 2 + Br 2 A halogen replaces another halogen
B. Predicting Single Replacement Products Al + Pb(NO 3)2
B. Predicting Single Replacement Products Ca + HCl
B. Predicting Single Replacement Products Chlorine Potassium iodide Cl 2 + KI
Will every single replacement reaction occur? NO!
C. The Activity Series • Single Replacement (SR) rxns only occur when a more reactive element replaces a less reactive element
C. The Activity Series Cont. Elements CANNOT replace anything ABOVE them. The reaction DOES NOT OCCUR in this situation. Ex: 2 K + 2 HCl 2 KCl + H 2 Mg + Li 2 O No Reaction (NR)
Write the chemical reaction and predict the products. Write NR if no reaction occurs. Zinc metal reacts with aqueous hydrochloric acid Copper metal reacts with aqueous hydrochloric acid
