Predict the products, write the equation and then balance. (As you can see, these are all decomposition reactions.)

1. chromium (III) carbonate à chromium (III) oxide + carbon dioxide

1 Cr⁺³₂(CO₃^-2)₃ à 1 Cr⁺³₂O^-2₃ + 3 CO₂

2. iron (III) hydroxide à iron (III) oxide + water

2 Fe⁺³(OH^-1)₃ à 1 Fe⁺³₂O^-2₃ + 3 H₂O

3. sodium chlorate à sodium chloride plus oxygen

2 Na⁺¹ClO^-1₃ à 2 NaCl + 3 O₂

4. phosphoric acid à water + diphosphorus pentoxide

2 H₃PO₄ à 3 H₂O + 1 P₂O₅

5. aluminum carbonate à aluminum oxide plus carbon dioxide

Al⁺³₂(CO₃^-2)₃ à Al⁺³₂O^-2₃ + 3 CO₂

_{OK, from here on out.... for ionic compounds, I will not be including charges (you have to, though)}

6. mercury (II) oxide à mercury + oxygen

2 HgO à 2 Hg + O₂

7. sulfurous acid à water + sulfur dioxide

1 H₂SO₃ à 1 H₂O + 1 SO₂

8. aluminum hydroxide à aluminum oxide + water

2 Al(OH)₃ à 1 Al₂O₃ + 3 H₂O

9. ammonium carbonate à ammonia + water + carbon dioxide

1 (NH₄)₂CO₃ à 2 NH₃ + 1 H₂O + 1 CO₂
