Classify the given chemical equations and scenarios as to SYNTHESIS, DECOMPOSITION, SINGLE REPLACEMENT, DOUBLE REPLACEMENT or COMBUSTION reaction. 1. When Al is placed on the surface of liquid Br2, an exothermic reaction occurs. The Al is oxidized to Al3+ by the Br2, which is reduced to Br - ions. The ionic product, AlBr3, can be observed on the watch glass after the reaction. ________________________________. 2. Al2(SO4)3 + BaCl2 → BaSO4 + AlCl3 ___________________________ 3. Al2S3 →Al + S ___________________________ 4. H2SO4 + Fe →H2 + FeSO4 ___________________________ 5. An aqueous solution of Potassium Iodide is added to an aqueous solution of Lead (II) Nitrate forming lead (II) iodide. The formation of a precipitate occurs when the cations of one reactant combines with the anions of the other reactant to form an insoluble or slightly insoluble compound. ___________________________________
