PAL— Classifying Chemical Reactions Part I: Classifying Chemical Reactions 1. Balance each of the following reactions. Reaction classiﬁcations options are shown in two boxes, box A and box B. Choose at least one option from each box for each reaction. If a reaction can be classiﬁed by more than 1 option, include those options as well. Solubility rules are located on the back of the worksheet. - Precipitation Redox Acid-Base Combustion Gas Forming - Synthesis Decomposition Single Displacement Double Displacement a. _____(NH4)2Cr2O7 (s) à _____H2O (g) + _____N2 (g) _____Cr2O3 (s) b. _____AgNO3 (aq) + _____NaCl (aq) à _____AgCl (s) + _____NaNO3 (aq) c. _____HNO3 (aq) + _____Ca(OH)2 à _____H2O (l) + _____Ca(NO3) (aq) d. ___K2CO3 (aq) + ___HCl (aq)à ___ KCl (aq) + ___H2O(l) + ___CO2(g) e. _____C8H18 (aq) + _____ O2 (g) à _____CO2 (g) + _____ H2O (l) f. _____Al(s) + _____ H2SO4 (aq) à _____ Al2(SO4)3 (aq) + _____ H2 (g) Part II: Predicting Products 2.
