Your turn A strip of magnesium metal is heated with nitrogen gas. A strip of iron is dropped into a solution of sulfuric acid. Phosphorus(V) oxide is sprinkled over distilled water. Magnesium oxide is stirred into distilled water. A small piece of calcium is dropped into distilled water. Sulfur dioxide is bubbled through a solution of potassium hydroxide. Solid magnesium oxide is added to a solution of hydrobromic acid. © 2009, Prentice-Hall, Inc.

Your turn (KEY) A strip of magnesium metal is heated with nitrogen gas. 3 Mg(s) + N2(g)  Mg3N2(s) A strip of iron is dropped into a solution of sulfuric acid. Fe(s) + H2SO4(aq)  FeSO4(aq) + H2(g) 3. Phosphorus(V) oxide is sprinkled over distilled water. P2O5(s) + 3 H2O(l)  2 H3PO4(aq) © 2009, Prentice-Hall, Inc.

Your turn (KEY) Magnesium oxide is stirred into distilled water. MgO(s) + H2O(l)  Mg(OH)2(s) A small piece of calcium is dropped into distilled water. Ca(s) + H2O(l)  Ca(OH)2(s) Sulfur dioxide is bubbled through a solution of potassium hydroxide. SO2(g) + 2 KOH(aq)  K2SO3(aq) + H2O(l) 7. Solid magnesium oxide is added to a solution of hydrobromic acid. MgO(s) + 2 HBr(aq)  MgBr2(aq) + H2O(l) © 2009, Prentice-Hall, Inc.
