Answer

Explanation:

Step1: Recall reaction - type definitions

Synthesis: A + B → AB; Decomposition: AB → A + B; Single - replacement: A + BC → AC + B; Double - replacement: AB+CD → AD + CB; Combustion: Hydrocarbon + O₂ → CO₂ + H₂O.

Step2: Analyze reaction 2

Pb + FeSO₄ → PbSO₄ + Fe. Here, Pb replaces Fe in FeSO₄. It is a single - replacement reaction.

Step3: Analyze reaction 3

P₄ + 3O₂ → 2P₂O₃. Phosphorus and oxygen combine to form a single product. It is a synthesis reaction.

Step4: Analyze reaction 4

2NO₂ → 2O₂ + N₂. A single compound breaks down into two elements. It is a decomposition reaction.

Step5: Analyze reaction 5

Na₃PO₄ + 3KOH → 3NaOH + K₃PO₄. The cations and anions of two compounds exchange places. It is a double - replacement reaction.

Step6: Analyze reaction 6

C₃H₆O + 4O₂ → 3CO₂ + 3H₂O. A compound containing carbon, hydrogen, and oxygen reacts with oxygen to produce carbon dioxide and water. It is a combustion reaction.

Step7: Analyze reaction 7

MgCl₂ + Li₂CO₃ → MgCO₃ + 2LiCl. The cations and anions of two compounds exchange. It is a double - replacement reaction.

Step8: Analyze reaction 8

C₆H₁₂ + 9O₂ → 6CO₂ + 6H₂O. A hydrocarbon reacts with oxygen to give carbon dioxide and water. It is a combustion reaction.

Step9: Analyze reaction 9

CaCO₃ → CaO + CO₂. A single compound breaks into two compounds. It is a decomposition reaction.

Step10: Analyze reaction 10

2AgNO₃ + Cu → Cu(NO₃)₂ + 2Ag. Cu replaces Ag in AgNO₃. It is a single - replacement reaction.

Step11: Analyze reaction 11

2H₂ + O₂ → 2H₂O. Hydrogen and oxygen combine to form water. It is a synthesis reaction.
