Answer to Question #114317 in General Chemistry for Kira-Nicole

Question

Synthesis, Decomposition, Combustion Practice
For each reaction, FIRST determine the general type (synthesis, decomposition, or combustion). Then determine the subcategory for each synthesis and decomposition (for synthesis a, b, or c; for decomposition a, b, c, d, e, or f). Once you have verified the reaction type against the answer key I will post, then predict the products for each reaction.

9. MgO + H2O Ú​
Type _____, _____

10. Na + Br2 à
Type _____, _____

Answer 1

1. 2NaHCO₃ =>​ Na₂CO₃ + H₂O + CO₂

Type: a thermal decomposition

2. SO₃ + H₂O => H₂SO₄

Type: synthese

3.Ca(ClO₃)₂ => CaCl₂ + 3O₂

Type: decomposition

4. K₂O + H₂O => 2KOH

Type: synthese

5. K₂CO₃ => K₂O + CO₂

Type: decomposition

6. C₁₂H₂₂O₁₁ + 12O₂ => 12CO₂ + 11H₂O

Type: combustion

7. H₂CO₃ =>​ CO₂ + H₂O

Type: decomposition

8. 2Al(OH)₃ => Al₂O₃ + 3H₂O

Type:  thermal decomposition 

9. MgO + H₂O => Mg(OH)₂

Type: synthese

10. 2Na + Br₂ => 2NaBr

Type: synthese
