Question

9
identify the reaction type: * (0.5 points)
____c₅h₁₂(l) + ____o₂(g) →
○ synthesis
○ decomposition
○ combustion
○ single replacement
○ double replacement

Explanation:

The reaction involves a hydrocarbon ($\ce{C5H12}$) reacting with oxygen ($\ce{O2}$). Combustion reactions are defined as reactions where a substance reacts with oxygen, usually producing carbon dioxide and water (though the products here are not fully shown, the reactants indicate a combustion setup). Synthesis involves combining simpler substances, decomposition is breaking down, single/double replacement involve ion exchanges, which don't fit here. So the reaction type is combustion.

Answer:

Combustion
