Question

select all the reaction types by what the atoms do.
☐ decomposition
☐ double displacement
☐ single displacement
☐ precipitation
☐ oxidation
☐ combination

Explanation:

To determine reaction types based on what atoms do:

• Decomposition: Atoms separate from a compound (e.g., \( \text{AB}

ightarrow \text{A} + \text{B} \)).

• Double Displacement: Atoms (ions) swap between two compounds (e.g., \( \text{AB} + \text{CD}

ightarrow \text{AD} + \text{CB} \)).

• Single Displacement: One atom replaces another in a compound (e.g., \( \text{A} + \text{BC}

ightarrow \text{AC} + \text{B} \)).

• Oxidation: Involves electron transfer (change in oxidation state).
• Combination: Atoms combine to form a compound (e.g., \( \text{A} + \text{B}

ightarrow \text{AB} \)).

Precipitation is a type of reaction based on product state (solid formation), not “what atoms do” (it’s a subset of double displacement, often). So the relevant types by atomic behavior are decomposition, double displacement, single displacement, oxidation, combination.

Answer:

• decomposition
• double displacement
• single displacement
• oxidation
• combination
