I'll help you identify each chemical reaction type. Let me work through each one carefully.
Step-by-step analysis:
1.
2KClO₃ → 2KCl + 3O₂
- One compound breaks down into two simpler substances
- This is a
decomposition reaction
2.
N₂ + 3H₂ → 2NH₃
- Two elements combine to form one compound
- This is a
synthesis reaction
3.
CH₄ + 2O₂ → CO₂ + 2H₂O
- A hydrocarbon reacts with oxygen to produce carbon dioxide and water
- This is a
combustion reaction
4.
N₂ + 3H₂ → 2NH₃
- Same as #2 - two elements combining to form one compound
- This is a
synthesis reaction
5.
2Al(OH)₃ + 3H₂SO₄ → Al₂(SO₄)₃ + 6H₂O
- Two compounds exchange parts (ions switch partners)
- This is a
double replacement reaction
6.
2HgO → 2Hg + O₂
- One compound breaks down into two simpler substances
- This is a
decomposition reaction
7.
Zn + 2HCl → ZnCl₂ + H₂
- An element replaces another element in a compound (Zn replaces H)
- This is a
single replacement reaction
8.
Fe₂(SO₄)₃ + 6KOH → 3K₂SO + 2Fe(OH)₃
- Two compounds exchange ions (partners switch)
- This is a
double replacement reaction
9.
C₇H₁₆ + 11O₂ → 7CO₂ + 8H₂O
- A hydrocarbon reacts with oxygen to produce CO₂ and H₂O
- This is a
combustion reaction
10.
2Na + 2H₂O → 2NaOH + H₂
- An element (Na) replaces hydrogen in water
- This is a
single replacement reaction
Final Answer:
1. Decomposition
2. Synthesis
3. Combustion
4. Synthesis
5. Double replacement
6. Decomposition
7. Single replacement
8. Double replacement
9. Combustion
10. Single replacement
