2. C. Johannesson A. Combustion CH 4 (g) + 2O 2 (g)  CO 2 (g) + 2H 2 O(g) n the burning of any substance in O 2 to produce heat A + O 2  B

3. C. Johannesson Na(s)+ O 2 (g)  C 3 H 8 (g)+ O 2 (g)  5 3 4 A. Combustion n Products:  contain oxygen  hydrocarbons form CO 2 + H 2 O CO 2 (g)+ H 2 O(g) Na 2 O(s) 4 2

4. C. Johannesson B. Synthesis n the combination of 2 or more substances to form a compound n only one product A + B  AB

5. C. Johannesson B. Synthesis H 2 (g) + Cl 2 (g)  2 HCl(g)

6. C. Johannesson Al(s)+ Cl 2 (g)  AlCl 3 (s) 2 3 2 B. Synthesis n Products:  ionic - cancel charges

7. C. Johannesson C. Decomposition n a compound breaks down into 2 or more simpler substances n only one reactant AB  A + B

8. C. Johannesson C. Decomposition 2 H 2 O(l)  2 H 2 (g) + O 2 (g)

9. C. Johannesson KBr(l)  K(s) + Br 2 (l) 2 2 C. Decomposition n Products:  binary - break into elements

10. C. Johannesson D. Single Replacement n one element replaces another in a compound  metal replaces metal (+)  nonmetal replaces nonmetal (-) A + BC  B + AC

11. C. Johannesson D. Single Replacement Cu(s) + 2AgNO 3 (aq)  Cu(NO 3 ) 2 (aq) + 2Ag(s)

12. C. Johannesson Fe(s)+ CuSO 4 (aq)  Cu(s)+ FeSO 4 (aq) D. Single Replacement n Products:  metal  metal (+)  nonmetal  nonmetal (-) Br 2 (l)+ NaCl(aq)  N.R.

13. C. Johannesson AB + CD  AD + CB E. Double Replacement n ions in two compounds “change partners” n Cation (+) of one compound combines with anion (-) of the other

14. C. Johannesson E. Double Replacement Pb(NO 3 ) 2 (aq) + K 2 CrO 4 (aq)  PbCrO 4 (s) + 2KNO 3 (aq)

15. C. Johannesson Pb(NO 3 ) 2 (aq)+ KI(aq)  PbI 2 (s)+ KNO 3 (aq) E. Double Replacement n Products:  switch negative ions NaNO 3 (aq)+ KI(aq)  N.R. 2 2
