Word Equations Worksheet Solutions Write the equations for the following chemical reactions: 1) When dissolved barium chloride reacts with dissolved potassium sulfate in water, barium sulfate precipitate and aqueous potassium chloride are made. BaCl2(aq) + K2SO4(aq)  BaSO4 (s) + 2 KCl(aq) 2) When calcium chloride and potassium phosphate are dissolved in water they react to form aqueous potassium chloride and calcium phosphate powder. 3 CaCl2 (aq) + 2 K3PO4(aq)  Ca3(PO4)2 (s) + 6 KCl (aq) + heat 3) When sucrose (C12H22O11) burns in oxygen, carbon dioxide, water and heat are produced. 2 C12H22O11 (s) + 24 O2 (g)  24 CO2 + 22 H2O (l) + heat 4) When dissolved calcium hydroxide reacts with sulfuric acid (H2SO4), a precipitate of calcium sulfate, water, and heat are formed. Ca(OH)2 (aq) + H2SO4 (aq)  CaSO4 (s) + 2 H2O (l) + heat 5) When sodium metal reacts with iron (III) chloride, iron metal and sodium chloride are formed. 3 Na(s) + FeCl3 (s)  Fe(s) + 3 NaCl(s)
