Classifying Chemical Reactions Reaction Types By classifying chemical reactions into several types, you can more easily predict what products are likely to form.

Al + Fe 2 O 3 → Fe + Al 2 O 3 Si

Combustion Reactions Is a the reaction of a carbon-based compound with oxygen. CH 4 (g) + O 2 (g) -> CO 2 (g) + H 2 O(l) C 3 H 8(g) + O 2(g) → CO 2(g) + H 2 O(l) CH 3 CH 2 OH(l) + O 2(g) → CO 2 + H 2 O C (x) H (y) + O 2(z) -> CO 2 + H 2 0

Synthesis Reactions Mg(s) + O 2 (g) → MgO(s) C + O 2 → CO 2 A + B -> AB

Decomposition Reactions H 2 O(l) + -e -> H 2 (g) + O 2 (g) H > H AB -> A + B

Displacement Reactions Cu(s) + AgNO 3 (aq) → Ag(s) + Cu(NO3) 2 (aq)

Single displacement Mg + Pb(NO3) 2 → Pb + Mg(NO3) 2 A + BX -> B + AX

Double-Displacement Reactions HCl(aq) + NaOH(aq) → HOH(l) + NaCl(aq) AX + BY -> AY + BX

Balance each of the equations below, and indicate the type of reaction for each equation. a. Cl 2 (g)  NaBr(aq)  NaCl(aq)  Br 2 (l) b. CaO(s)  H 2 O(l) -> Ca(OH) 2 (aq) c. Ca(ClO 3 ) 2 (s)  CaCl 2 (s)  O 2 (g) d. AgNO 3 (aq)  K 2 SO 4 (aq) ->Ag 2 SO 4 (s)  KNO 3 (aq)

Predict whether a reaction would occur when the materials indicated are brought together. For each reaction that would occur, complete and balance the equation. a. Ag(s)  H 2 O(l) b. Mg(s)  Cu(NO 3 ) 2 (aq) c. Al(s)  O 2 (g) d. H 2 SO 4 (aq)  KOH(aq)

Predict the products, write a balanced equation, and identify the type of reaction for each of the following reactions. a. HgO  b. C 3 H 7 OH  O 2  c. Zn  CuSO 4  d. BaCl 2  Na 2 SO 4  e. Zn  F 2  f. C 5 H 10  O 2 
