1 Chemistry: Chemical Word Equations Directions: Write a balanced chemical equation for each of the word equations below.

2 Write out the symbols- be sure the subscripts are correct! aqueous sodium chloride reacts with aqueous lead (II) nitrate to yield a lead (II) chloride precipitate and aqueous sodium nitrate sodium chloride + lead (II) nitrate lead (II) chloride + sodium nitrate

3 NaCl + Pb(NO 3 ) 2 → PbCl 2 + NaNO 3 2 NaCl (aq) + Pb(NO 3 ) 2 (aq) → PbCl 2 (ppt) + 2 NaNO 3 (aq)

4 aqueous barium nitrate reacts with sulfuric acid [H2SO4(aq)] to yield a barium sulfate precipitate and nitric acid [HNO3(aq)] barium nitrate + sulfuric acid → barium sulfate + nitric acid

5 Ba(NO 3 ) 2 + H 2 SO 4 → BaSO 4 + HNO 3 Ba(NO 3 ) 2 (aq) + H 2 SO 4 (aq) → BaSO 4 (ppt) + 2 HNO 3 (aq)

6 silver nitrate reacts in solution with potassium chromate to yield a silver chromate precipitate and soluble potassium nitrate silver nitrate + potassium chromate silver chromate + potassium nitrate

7 AgNO 3 (s) + K 2 CrO 4 (aq) → Ag 2 CrO 4 (ppt) + KNO 3 (aq) AgNO 3 (s) + K 2 CrO 4 (aq) → Ag 2 CrO 4 (ppt) + 2 KNO 3 (aq)

8 solid calcium carbonate reacts with hydrochloric acid [HCl(aq)] to yield aqueous calcium chloride, carbon dioxide gas, and liquid water calcium carbonate + hydrochloric acid yields calcium chloride + carbon dioxide + water

9 CaCO 3 + HCl(aq) → CaCl 2 (aq) + H 2 CO 3 (aq) CO 2 (g) + H 2 O (l) CaCO 3 (s) + 2 HCl(aq) → CaCl 2 (aq) + H 2 CO 3 (aq) CO 2 (g) + H 2 O (l)

10 aqueous zinc chloride reacts with dihydrogen monosulfide gas to yield a zinc sulfide precipitate and hydrochloric acid zinc chloride + dihydrogen monosulfide yieldszinc sulfide + hydrochloric acid

11 ZnCl 2 + H 2 S →ZnS + HCl ZnCl 2 (aq) + H 2 S(g) ZnS (ppt) + 2 HCl (aq)

12 magnesium nitrate reacts in solution with potassium hydroxide to yield a magnesium hydroxide precipitate and soluble potassium nitrate

13 magnesium nitrate + potassium hydroxide magnesium hydroxide + potassium nitrate

14 Mg(NO 3 ) 2 + KOH →Mg(OH) 2 + KNO 3 Mg(NO 3 ) 2 (aq) + 2 KOH (aq) Mg(OH) 2 (ppt) + 2 KNO 3 (aq)

15 solid aluminum hydroxide reacts with nitric acid to yield soluble aluminum nitrate and liquid water

16 aluminum hydroxide + nitric acid aluminum nitrate + water

17 Al(OH) 3 + HNO 3 → Al(NO 3 ) 3 + H 2 O Al(OH) 3 (s) + 3 HNO 3 (aq) → Al(NO 3 ) 3 (aq) + 3 H 2 O (aq)

18 aqueous lead (IV) nitrate reacts with aqueous sodium sulfate to yield a lead (IV) sulfate precipitate and soluble sodium nitrate

19 lead (IV) nitrate + sodium sulfate → lead(IV) sulfate + sodium nitrate

20 Pb(NO 3 ) 4 + Na 2 SO 4 → Pb(SO 4 ) NaNO 3 Pb(NO 3 ) 4 (aq) + 2 Na 2 SO 4 (aq) → Pb(SO 4 ) 2 (s) + 4 NaNO 3 (aq)
