1 Review of Ch 9 & 11 Writing and Balancing Equations

2 Writing Formulas a. Magnesium sulfide b. Sodium phosphate c. Barium hydroxide d. Copper (II) nitrite e. Trihydrogen bromide f. Calcium carbonate g. Hexafluoride pentanitride h. Iron (III) sulfate MgS Na 3 PO 4 Ba(OH) 2 Cu(NO 2 ) 2 H 3 Br CaCO 3 F6N5F6N5 Fe 2 (SO4) 3

3 Naming a. NaClO 3 b. Hg 2 Br 2 c. K 2 CrO 4 d. HClO 4 e. SnO 2 f. Fe(C 2 H 3 O 2 ) 3 g. Ca(OH) 2 Sodium chlorite Mercury (I) bromide Potassium chromate Hydrogen chlorate Tin (IV) oxide Iron (III) acetate Calcium hydroxide

4 Balance a. PbO 2  PbO + O 2 b. Fe(OH) 3  Fe 2 O 3 + H 2 O c. (NH 4 ) 2 CO 3  NH 3 + H 2 O + CO 2 d. NaCl + H 2 SO 4  Na 2 SO 4 + HCl 2PbO 2  2PbO + O 2 2Fe(OH) 3  Fe 2 O 3 + 3H 2 O (NH 4 ) 2 CO 3  2NH 3 + H 2 O + CO 2 2NaCl + H 2 SO 4  Na 2 SO 4 + 2HCl

5 Type? a. Hf + N 2  Hf 3 N 4 b. Mg + H 2 SO 4  MgSO 4 + H 2 c. C 2 H 6 + O 2  CO 2 + H 2 O d. Pb(NO 3 ) 2 + NaI  PbI 2 + NaNO 3 e. Fe + O 2  Fe 3 O 4

6 Write a Complete Chemical Equation 1. Bubbling chlorine gas through a solution of potassium iodide give elemental iodine and a solution of potassium chloride. 2. Solid tetraphosphorus decoxide reacts with water to produce phosphoric acid.

7 Predict the Products 1. C 3 H 8 reacts with oxygen 2. Copper reacts with aqueous silver nitrate 3. Aluminum reacts with bromine 4. Lead (II) nitrate reacts with potassium iodide

8 Predict the Products 1. C 3 H 8 reacts with oxygen 2. Copper (II) reacts with aqueous silver nitrate 3. Aluminum reacts with bromine 4. Lead (II) nitrate reacts with potassium iodide C 3 H 8 + 5O 2  3CO 2 + 4H 2 O Cu + 2AgNO 3  Cu(NO 3 ) 2 + 2Ag 2Al + 3Br 2  2AlBr 3 Pb(NO 3 ) 2 + KI  KNO 3 + PbI 2
