Question

what type of reaction is c₂h₂ + o₂ → co₂ + h₂o? decomposition synthesis combustion single replacement none of these

Explanation:

Step1: Analyze combustion reaction characteristics

Combustion reactions involve a substance reacting with oxygen, usually producing carbon dioxide and water.

Step2: Check the given reaction

In \(C_{2}H_{2}+O_{2}\to CO_{2}+H_{2}O\), acetylene (\(C_{2}H_{2}\)) reacts with oxygen (\(O_{2}\)) to form carbon dioxide (\(CO_{2}\)) and water (\(H_{2}O\)), which matches combustion reaction features.

Answer:

Combustion
