Oct 13, 2025 by wbrum.org 30 views

Chemical equations are a fundamental concept in chemistry, allowing us to represent and understand the interactions between different substances. A balanced chemical equation is a crucial aspect of this concept, as it ensures that the number of atoms of each element is the same on both the reactant and product sides. In this article, we will explore the balanced equation for the reaction between butane and oxygen, producing carbon dioxide and water.

What is a Balanced Chemical Equation?

A balanced chemical equation is a representation of a chemical reaction where the number of atoms of each element is the same on both the reactant and product sides. This is achieved by adjusting the coefficients of the reactants and products, ensuring that the law of conservation of mass is satisfied. The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction, only transformed from one substance to another.

The Reaction Between Butane and Oxygen

Butane (C4H10) is a hydrocarbon that burns in oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). The balanced equation for this reaction is:

$2 C_4 H_{10} + 13 O_2 \rightarrow 8 CO_2 + 10 H_2 O$

Understanding the Balanced Equation

Let's break down the balanced equation and understand the reaction:

Reactants: Butane (C4H10) and oxygen (O2) are the reactants in this equation.
Products: Carbon dioxide (CO2) and water (H2O) are the products of this reaction.
Coefficients: The coefficients of the reactants and products are adjusted to ensure that the number of atoms of each element is the same on both sides. In this equation, the coefficient of butane is 2, and the coefficient of oxygen is 13.

Why is the Equation Balanced?

The equation is balanced because the number of atoms of each element is the same on both the reactant and product sides. Let's count the number of atoms of each element:

Carbon (C): There are 8 carbon atoms on the product side (8 CO2 molecules, each containing 1 carbon atom). On the reactant side, there are 8 carbon atoms (2 C4H10 molecules, each containing 4 carbon atoms).
Hydrogen (H): There are 20 hydrogen atoms on the product side (10 H2O molecules, each containing 2 hydrogen atoms). On the reactant side, there are 20 hydrogen atoms (2 C4H10 molecules, each containing 10 hydrogen atoms).
Oxygen (O): There are 26 oxygen atoms on the product side (8 CO2 molecules, each containing 2 oxygen atoms, and 10 H2O molecules, each containing 1 oxygen atom). On the reactant side, there are 26 oxygen atoms (13 O2 molecules, each containing 2 oxygen atoms).

Conclusion

In conclusion, the balanced equation for the reaction between butane and oxygen is:

$2 C_4 H_{10} + 13 O_2 \rightarrow 8 CO_2 + 10 H_2 O$

This equation is balanced because the number of atoms of each element is the same on both the reactant and product sides. Understanding balanced chemical equations is crucial in chemistry, as it allows us to represent and understand the interactions between different substances.
