Question:

Classify as to what type of chemical reaction each one belongs:

1. $\mathrm{H}_2\mathrm{CO}_3 \rightarrow \mathrm{H}_2\mathrm{O} + \mathrm{CO}_2$

2. $\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6} \rightarrow 12 \mathrm{C} + 11 \mathrm{H}_{2} \mathrm{O}$

3. $\mathrm{CdCl}_2 + \mathrm{H}_2\mathrm{S} \rightarrow \mathrm{CdS} + 2\mathrm{HCl}$

4. $2\mathrm{Al} + \mathrm{O}_2 \rightarrow \mathrm{Al}_2\mathrm{O}_3$

5. $\mathrm{Mg} + \mathrm{H}_2\mathrm{SO}_4 \rightarrow \mathrm{MgSO}_4 + \mathrm{H}_2$

6. $\mathrm{CaCO}_3 \rightarrow \mathrm{CaO} + \mathrm{CO}_2$

7. $\mathrm{Na}_{2} \mathrm{O} + \mathrm{H}_{2} \mathrm{O} \rightarrow 2 \mathrm{NaOH}$

8. $\mathrm{FeCl}_3 + 3\mathrm{NaOH} \rightarrow \mathrm{Fe(OH)}_3 + 3\mathrm{NaCl}$

9. $3\mathrm{H}_{2} + \mathrm{Fe}_{2}\mathrm{O}_{3} \rightarrow 3\mathrm{H}_{2}\mathrm{O} + 2\mathrm{Fe}$

10. $2\mathrm{H}_{2} + \mathrm{O}_{2} \rightarrow 2\mathrm{H}_{2}\mathrm{O}$

Answer:

1. $\mathrm{H}_2\mathrm{CO}_3 \rightarrow \mathrm{H}_2\mathrm{O} + \mathrm{CO}_2$ – decomposition reaction

2. $\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6} \rightarrow 12 \mathrm{C} + 11 \mathrm{H}_{2} \mathrm{O}$ – decomposition reaction

3. $\mathrm{CdCl}_2 + \mathrm{H}_2\mathrm{S} \rightarrow \mathrm{CdS} + 2\mathrm{HCl}$ – double displacement reaction

4. $2\mathrm{Al} + \mathrm{O}_2 \rightarrow \mathrm{Al}_2\mathrm{O}_3$ – synthesis reaction

5. $\mathrm{Mg} + \mathrm{H}_2\mathrm{SO}_4 \rightarrow \mathrm{MgSO}_4 + \mathrm{H}_2$ – single displacement reaction

6. $\mathrm{CaCO}_3 \rightarrow \mathrm{CaO} + \mathrm{CO}_2$ – decomposition reaction

7. $\mathrm{Na}_{2} \mathrm{O} + \mathrm{H}_{2} \mathrm{O} \rightarrow 2 \mathrm{NaOH}$ – synthesis reaction

8. $\mathrm{FeCl}_3 + 3\mathrm{NaOH} \rightarrow \mathrm{Fe(OH)}_3 + 3\mathrm{NaCl}$ – double displacement reaction

9. $3\mathrm{H}_{2} + \mathrm{Fe}_{2}\mathrm{O}_{3} \rightarrow 3\mathrm{H}_{2}\mathrm{O} + 2\mathrm{Fe}$ – single displacement reaction

10. $2\mathrm{H}_{2} + \mathrm{O}_{2} \rightarrow 2\mathrm{H}_{2}\mathrm{O}$ – synthesis reaction
