1 Chapter 9 Review 1.AgNO 3 + H 2 SO 4  Ag 2 SO 4 +HNO 3 What is the ratio of coefficients: 2 : 1 : 1 : 2 Is there a precipitate formed? yes. Ag 2 SO 4, rule #4. What are the spectator ions? H + and NO 3 - What is the net ionic equation? 2Ag + + SO 4 2-  Ag 2 SO 4

2 2.K 2 SO 3(aq)  K 2 O (aq) + SO 2 (g) What type of reaction is this? Decomposition What is the ratio of the coefficients? 1:1:1 Which compound(s) will dissolve in water? K 2 SO 3 and K 2 O Which compound(s) is a gas? SO 2(g)

3 3. PbCl 2 + Li 2 SO 4  PbSO 4 + LiCl What type of reaction is this? Double replacement What are the ratio of coefficients? No reaction Is a precipitate formed? No reaction What symbol would be used to indicate for PbCl 2 ? (s)

4 4.Cl 2 + KBr  What type of reaction is this? Single replacement Which activity series is used? Nonmetal, Cl - replaces Br - How would you write the gas of bromine? Br 2 What is the ratio of coefficients? 1:2:2:1

5 5. Al + Pb(NO 3 ) 3  Will this reaction take place? Yes, Pb is less active than Al What is the product?  Al(NO 3 ) 3 + Pb Is there a precipitate? yes? Pb is a metal and will fall out. What is the ratio of coefficients? 1:1:1:1

6 6. (NH 4 ) 2 SO 4 + Ca(OH) 2  What is the product?  NH 4 OH + CaSO 4 What are the ratio of coefficients? 1:1:2:1 Is there a precipitate? yes, CaSO 4 What are the spectator ions? NH 4 + and OH -

7 7. The compounds and molecules that reforms in a chemical reaction is called: ans: product 8. Characteristic of the produce is CO 2 and water: ans: combustion reaction 9. When two or more elements or compounds form a single product: ans: synthesis or combination

8 10. When a compound like FeO or a ∆ symbol are seen over the ‘to yield’ arrow: ans: catalyst 11. Ions that do NOT take part in the formation of precipitate in a reaction: ans: spectator ions 12. The ONLY number in a balanced equation that can be changed: and: coefficient

9 13. This is used in a single replacement reaction to determine if the reaction will proceed? ans: activity series 14. Characterized by a compound + compound in the reactant: ans: double replacement 15. What is leftover after the spectator ions are removed: ans: net ionic equation

10 16. Characterized by having the same number and type of matter on both sides of the ‘to yield’ arrow: ans: balanced equation 17. Given 2Fe 3 (PO 3 ) 2, the number of each element in this compound: Fe P O

11 1.Aqueous solutions of lead (II) nitrate and ammonium chloride are mixed  2.Aqueous solution of aluminum chloride and sodium carbonate combine  3.Sulfuric acid reacts with sodium hydroxide  4.Sodium sulfide reacts with hydrochloric acid 

12 1.If water is the product in the net ionic equation in an acid/base reaction, what does this tell you about the reaction? 2.What type of solution would you have if all the reactants and products were soluble? 3.Where would a net ionic reaction be useful? Hint spectator ions.
