Question

For the reaction C₆H₁2 + 9O₂ → 6CO₂ + 6H₂O, the type of reaction is:

a) Combustion
b) Synthesis
c) Decomposition
d) Double displacement

Answer 1

A) Combustion Reaction

Step-by-step explanation:

For combustion reactions, we can often observe the products being carbon dioxide and water (which we see here). Furthermore, we see that on the left side of the reaction, we have oxygen as a reactant; another characteristic of combustion reactions.

I don't think you'd be expected to know it based on the question, but C6H12 is cyclohexane, a very flammable liquid. When it reacts with oxygen and a source of heat, it is combustible.

Answer 2

The reaction in question is a combustion reaction, where a hydrocarbon reacts with oxygen to produce carbon dioxide and water.

Step-by-step explanation:

The reaction C₆H₁₂ + 9O₂ → 6CO₂ + 6H₂O is a combustion reaction. In combustion reactions, a substance reacts with oxygen, often with the release of energy in the form of heat and sometimes light. The given reaction shows the hydrocarbon C₆H₁₂ reacting with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O), which are typical products of combustion. Therefore, the correct answer to the question is a) Combustion.
