Introduction

Butane, a highly flammable and widely used hydrocarbon, is a key component in various industrial and domestic applications. Its combustion reaction is a crucial process that releases a significant amount of energy, making it an essential aspect of various industries, including power generation, transportation, and heating. In this article, we will delve into the combustion of butane, exploring its chemical equation, stoichiometry, and the implications of its reaction with an excess of oxygen.

The Combustion Reaction of Butane

The combustion reaction of butane is represented by the following equation:

${2C_4H_{10}(g) + 13O_2(g) \rightarrow 8CO_2(g) + 10H_2O(l)}$

In this equation, butane ( ${C_4H_{10}}$ ) reacts with oxygen ( ${O_2}$ ) to produce carbon dioxide ( ${CO_2}$ ) and water ( ${H_2O}$ ). The reaction is highly exothermic, releasing a significant amount of energy in the form of heat and light.

Stoichiometry of the Combustion Reaction

To understand the stoichiometry of the combustion reaction, we need to analyze the coefficients of the reactants and products. The balanced equation shows that 2 moles of butane react with 13 moles of oxygen to produce 8 moles of carbon dioxide and 10 moles of water.

Calculating the Amount of Oxygen Required

To determine the amount of oxygen required for the combustion of butane, we can use the mole ratio of butane to oxygen from the balanced equation. The mole ratio is 2:13, indicating that 2 moles of butane require 13 moles of oxygen for complete combustion.

Calculating the Amount of Carbon Dioxide Produced

Similarly, we can calculate the amount of carbon dioxide produced by the combustion of butane using the mole ratio of butane to carbon dioxide from the balanced equation. The mole ratio is 2:8, indicating that 2 moles of butane produce 8 moles of carbon dioxide.

Calculating the Amount of Water Produced

Finally, we can calculate the amount of water produced by the combustion of butane using the mole ratio of butane to water from the balanced equation. The mole ratio is 2:10, indicating that 2 moles of butane produce 10 moles of water.

Applying the Calculations to a Real-World Scenario

Let's consider a real-world scenario where 4.10 moles of butane are reacted with an excess of oxygen. We can use the calculations above to determine the amount of oxygen required, carbon dioxide produced, and water produced.

Calculating the Amount of Oxygen Required

Using the mole ratio of butane to oxygen from the balanced equation, we can calculate the amount of oxygen required for the combustion of 4.10 moles of butane:

${ \text{Oxygen required} = \frac{13}{2} \times 4.10 = 26.65 \text{ moles} }$

Calculating the Amount of Carbon Dioxide Produced

Using the mole ratio of butane to carbon dioxide from the balanced equation, we can calculate the amount of carbon dioxide produced by the combustion of 4.10 moles of butane:

${ \text{Carbon dioxide produced} = \frac{8}{2} \times 4.10 = 16.40 \text{ moles} }$

Calculating the Amount of Water Produced

Finally, using the mole ratio of butane to water from the balanced equation, we can calculate the amount of water produced by the combustion of 4.10 moles of butane:

${ \text{Water produced} = \frac{10}{2} \times 4.10 = 20.50 \text{ moles} }$

Conclusion

In conclusion, the combustion of butane is a highly exothermic reaction that releases a significant amount of energy in the form of heat and light. By analyzing the stoichiometry of the combustion reaction, we can calculate the amount of oxygen required, carbon dioxide produced, and water produced by the combustion of butane. In a real-world scenario, 4.10 moles of butane reacted with an excess of oxygen would require 26.65 moles of oxygen, produce 16.40 moles of carbon dioxide, and produce 20.50 moles of water.
