2. C 3 H 8 (g)+ O 2 (g) 5 3 4 A. Combustion n Reactants: Hydrocarbons O 2 n Products: contain oxygen hydrocarbons form CO 2 + H 2 O CO 2 (g)+ H 2 O(g)

3. Al(s)+ Cl 2 (g) AlCl 3 (s) 2 3 2 B. Synthesis n Reactants: More than one substance n Products: Only one substance ionic - cancel charges covalent - hard to tell

4. KBr(l) K(s) + Br 2 (l) 2 2 C. Decomposition n Reactants: Only one reactant n Products: binary - break into elements others - hard to tell

5. Fe(s)+ CuSO 4 (aq) Cu(s)+ FeSO 4 (aq) D. Single Replacement n Products: metal metal (+) nonmetal nonmetal (-) free element must be more active (check activity series) Br 2 (l)+ NaCl(aq) N.R.

6. Pb(NO 3 ) 2 (aq)+ KI(aq) PbI 2 + KNO 3 E. Double Replacement n Products: switch negative ions one product must be insoluble (check solubility table) NaNO 3 (aq)+ KI(aq) N.R. 2 2 (s) (aq) NaI + KNO 3 NaI (aq) + KNO 3 (aq)
