Question

identify the type of reaction for the chemical equation $\ce{c_{3}h_{8} + 5o_{2} -> 3co_{2} + 4h_{2}o}$. options: decomposition, single replacement, synthesis, combustion

Explanation:

The chemical equation \( \text{C}_3\text{H}_8 + 5\text{O}_2
ightarrow 3\text{CO}_2 + 4\text{H}_2\text{O} \) involves a hydrocarbon (\( \text{C}_3\text{H}_8 \), propane) reacting with oxygen (\( \text{O}_2 \)) to produce carbon dioxide (\( \text{CO}_2 \)) and water (\( \text{H}_2\text{O} \)). This fits the definition of a combustion reaction, where a fuel (hydrocarbon) reacts with oxygen, releasing energy and producing these products. Decomposition involves breaking down a compound, single replacement involves one element replacing another in a compound, and synthesis involves combining substances into a single compound—none of these match this reaction.

Answer:

D. Combustion
