Identify the type of reaction

C4H10(g) + O2(g) ! CO2(g) + H2O(g)
1. hydrocarbon synthesis
2. single displacement
3. incomplete combustion
4. complete combustion

Complete combustion

To identify the type of reaction for the given chemical equation, we need to analyze the reactants and products involved.

The chemical equation provided is:

C4H10(g) + O2(g) → CO2(g) + H2O(g)

Looking at the reactants, we have C4H10 (butane) and O2 (oxygen). Butane is a hydrocarbon and oxygen is a diatomic molecule.

Analyzing the products, we have CO2 (carbon dioxide) and H2O (water).

Based on this information, we can determine the type of reaction.

1. Hydrocarbon synthesis involves the combination of hydrocarbon compounds to form larger or more complex hydrocarbons. However, in the given equation, butane (C4H10) is not forming a larger or more complex hydrocarbon. Therefore, it is not a hydrocarbon synthesis reaction.

2. Single displacement reactions involve the replacement of an element in a compound with another element. There is no evidence of elements being replaced in this equation. Therefore, it is not a single displacement reaction.

3. Incomplete combustion occurs when there is a limited oxygen supply, resulting in the formation of incomplete products such as carbon monoxide (CO) or soot. However, the given equation does not involve the formation of carbon monoxide or soot. Therefore, it is not an incomplete combustion reaction.

4. Complete combustion involves the reaction of a hydrocarbon with oxygen, resulting in the complete conversion of the hydrocarbon to carbon dioxide and water. In the given equation, we observe the formation of carbon dioxide (CO2) and water (H2O), indicating complete combustion.

Therefore, the correct answer is:

4. Complete combustion

The type of reaction shown is number 4, complete combustion.
