1. Reactions in Aqueous Solutions Chapter 7

2. Synthesis – 1 product Decomposition – 1 reactant Single displacement – 1 element & 1 compound react to produce a different element & a different compound Double displacement – 2 compounds react to form two different compounds. Neutralization – acid and base in the reactants & water as one of the products. Combustion – O 2 as a reactant & CO 2 and H 2 O as the products. Determining Types of Reactions

3. Synthesis – two or more reactants and only 1 product. H 2(g) + O 2(g)  H 2 O (l) Na (s) + Cl 2(g)  NaCl (s) Determining the type of reaction

4. Decomposition – only 1 reactant and 2 or more products. 2 HgO (l)  2 Hg (l) + O 2(g) NaHCO 3(s)  Na 2 CO 3(s) + H 2 O (l) + CO 2(g) Determining the type of reaction

5. Single displacement – 1 element and 1 compound in the reactants and a different element and a different compound in the products. CuCl 2(aq) + Mg (s)  MgCl 2(aq) + Cu (s) KCl (aq) + F 2(g)  KF (aq) + Cl 2(g) Determining the type of reaction

6. Double displacement - two compounds in the reactants and two different compounds in the products. FeCl 3(aq) +MgSO 4(aq)  Fe 2 (SO 4 ) 3(s) +MgCl 2(aq) NaCl (aq) + AgNO 3(aq)  NaNO 3(aq) + AgCl (s) Determining the type of reaction

7. Neutralization (acid-base) – an acid and a base in the reactants and water as one of the products. HCl (aq) + NaOH (aq)  NaCl (aq) + H 2 O (l) acid base Ca(OH) 2(aq) + H 3 PO 4(aq)  H 2 O (l) +Ca 3 (PO 4 ) 2(aq) base acid Determining the type of reaction

8. Combustion – a hydrocarbon and oxygen as a reactants and carbon dioxide and water as the only products. CH 4(g) + O 2(g)  CO 2(g) + H 2 O (g) C 8 H 18(g) + O 2(g)  CO 2(g) + H 2 O (g) Determining the type of reaction

9. Determine the type of reaction for each of the following examples: PbCl 2(aq) + KClO 3(aq)  Pb(ClO 3 ) 2(aq) + KCl (aq) K (s) + F 2(g)  KF (aq) LiOH (aq) + H 2 SO 4(aq)  H 2 O (l) +Li 2 (SO 4 ) 2(aq) C 6 H 12 O 6(aq)  CO 2(g) + H 2 O (g) C 3 H 8(g) + O 2(g)  CO 2(g) + H 2 O (g) MgBr 2(aq) + Cl 2(g)  MgCl 2(aq) + Br 2(l) More Examples
