Transcript text: Identify the reaction type for each generic chemical equation. \[ \begin{array}{l} A+B \rightarrow A B: \quad \text { ( } \\ A B \rightarrow A+B: \end{array} \] \[ \begin{array}{l} \text { Hydrocarbon }+\mathrm{O}_{2} \rightarrow \mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O} \text { : } \\ \mathrm{AB}+\mathrm{CD} \rightarrow \mathrm{AD}+\mathrm{CB}: \end{array} \]

Solution

Solution Steps

Step 1: Identify the Reaction Type for \( A + B \rightarrow AB \)

This reaction involves two reactants combining to form a single product. This type of reaction is known as a synthesis reaction.

Step 2: Identify the Reaction Type for \( AB \rightarrow A + B \)

This reaction involves a single compound breaking down into two or more products. This type of reaction is known as a decomposition reaction.

Step 3: Identify the Reaction Type for Hydrocarbon + \( \mathrm{O}_2 \rightarrow \mathrm{CO}_2 + \mathrm{H}_2\mathrm{O} \)

This reaction involves a hydrocarbon reacting with oxygen to produce carbon dioxide and water. This type of reaction is known as a combustion reaction.

Step 4: Identify the Reaction Type for \( \mathrm{AB} + \mathrm{CD} \rightarrow \mathrm{AD} + \mathrm{CB} \)

This reaction involves the exchange of ions between two compounds to form two new compounds. This type of reaction is known as a double displacement reaction.

Final Answer

\[ \begin{array}{l} A + B \rightarrow AB: \quad \text{synthesis reaction} \\ AB \rightarrow A + B: \quad \text{decomposition reaction} \\ \text{Hydrocarbon} + \mathrm{O}_2 \rightarrow \mathrm{CO}_2 + \mathrm{H}_2\mathrm{O}: \quad \text{combustion reaction} \\ \mathrm{AB} + \mathrm{CD} \rightarrow \mathrm{AD} + \mathrm{CB}: \quad \text{double displacement reaction} \end{array} \]

\(\boxed{\text{synthesis reaction, decomposition reaction, combustion reaction, double displacement reaction}}\)
