Answer :

To determine the type of chemical reaction depicted by the equation:

[tex]\[ 2 C_4H_{10}(g) + 13 O_2(g) \rightarrow 8 CO_2(g) + 10 H_2O(g) \][/tex]

we can analyze the reactants and products involved in this reaction. Let's break it down step-by-step:

1. Identify the Reactants:
- The reactants given in the equation are \( C_4H_{10} \) (butane), a hydrocarbon, and \( O_2 \) (oxygen).

2. Identify the Products:
- The products are \( CO_2 \) (carbon dioxide) and \( H_2O \) (water).

3. Type of Reaction:
- In chemistry, a combustion reaction involves a hydrocarbon reacting with oxygen to produce carbon dioxide and water. Combustion reactions are typically exothermic, meaning they release heat.

4. Compare with Reaction Types:
- Combustion: As discussed above, this type of reaction involves a hydrocarbon and oxygen producing carbon dioxide and water, fitting the given equation perfectly.
- Single-Replacement: Involves one element replacing another in a compound; this does not fit the description of the given reaction.
- Combination: Involves two or more reactants combining to form one product; the given reaction involves multiple products.
- Decomposition: Involves a single compound breaking down into two or more simpler substances; the given reaction starts with two reactants and produces multiple products.

Based on the described characteristics of these reaction types, the reaction given in the equation:

[tex]\[ 2 C_4H_{10}(g) + 13 O_2(g) \rightarrow 8 CO_2(g) + 10 H_2O(g) \][/tex]

matches the description of a combustion reaction. Therefore, the correct answer is:

### A. Combustion
