Reaction Prediction You will learn guidelines for Predicting Products of Selected Reactions Ws. 8.6, 8.7 Chemistry Table Reaction Prediction Synthesis A synthesis reaction will occur provided the two the elements involved are capable of demonstrating opposite valences. 1a. Formation of binary compounds A+B AB H2 + Cl2 Mg + Br2 Na + Cl2 2b. Metal-oxide + H20 base CaO + H20 Na2O + H20 2c. NM-oxide + H2O SO2 + H2O CO2 + H2O acids Decomposition Needs heat, light, electricity Decomposition of a substance by electricity is called electrolysis 2a. Binary Compound AB HgO NaN3 A+B 2b. M-carbonates: MCO3 M-oxides + CO2 CaCO3 Na2CO3 2c. M-hydrogen carbonate: MHCO3 MO + H2O + CO2 NaHCO3 d. M-hydroxides: MOH MO + H2O NaOH Ca(OH)2 e. M-chlorates: MClO3 KClO3 Fe(ClO3)2 MCl + O2 f. Oxyacids : acid NMO + H2O H2CO3 H2SO4 Single Replacement 3a Metal – Metal replacement A + BC AC+B Al + Fe(NO3)2 Al + ZnCl2 Co + NaCl 3b. Active metal (group 1 &2) replaces H from water: M + H2O MOH + H2 Na + H2O Li + H2O ? Will it replace hydrogen from H2O? …….. Look on chart 3c. Active Metal replaces H from acid: M + HX MX + H2 Mg + HCl Zn + HCl Zn + H2SO4 ?will it replace H from acids …..look on chart? 3d. Halide – Halide replacement F2 one halogen replace another halogen Cl2 D+ BC Br2 I2 Cl2 + KBr F2 + NaCl Br2 + KCl BD+C Identify the element that replaces hydrogen from acids but cannot replace tin from compounds? According to the table, what is the most active transitional metal? Double Replacement 4a. Formation of a (ppt) from a solution l. Both reactants must be soluble 2. All DR will produce a (ppt), (g), H2O. 3. must use solubility chart KI + Pb(NO3)2 Ba(NO3) + Na2SO4 ****4b. Acid + Base Neutralization Hfirst end (OH) HCl + NaOH H2SO4 + Ba(OH)2 HNO3 + Ca(OH)2 HC2H3O2 + Ba(OH)2 H2CO3 + Ca(OH)2 H3PO4 + K(OH) practice 1. NaI + CaCl2 2. HNO3 + Mn(OH)2 3. AgNO2 + BaSO4 4. LiBr + AgNO3 5.
