Introduction

Chemical equations are a fundamental concept in chemistry, representing the transformation of one or more substances into another. In this article, we will explore the process of balancing intermediate chemical equations, focusing on the given equations:

{ \begin{array}{l} C(s) + \frac{1}{2} O_2(g) \rightarrow CO(g) \\ CO(g) + \frac{1}{2} O_2(g) \rightarrow CO_2(g) \end{array} \}

Understanding the Given Equations

The first equation represents the reaction between carbon (C) and oxygen (O2) to form carbon monoxide (CO). The second equation shows the reaction between carbon monoxide (CO) and oxygen (O2) to form carbon dioxide (CO2).

Balancing the Equations

To balance the equations, we need to ensure that the number of atoms of each element is the same on both the reactant and product sides. Let's start by balancing the first equation:

Balancing the First Equation

The first equation is:

C(s) + 1/2 O2(g) → CO(g)

To balance this equation, we need to multiply the carbon (C) by 1 and the oxygen (O2) by 1. However, since the oxygen is in the form of O2, we need to multiply the entire equation by 2 to get rid of the fraction:

2C(s) + O2(g) → 2CO(g)

Now, let's balance the second equation:

Balancing the Second Equation

The second equation is:

CO(g) + 1/2 O2(g) → CO2(g)

To balance this equation, we need to multiply the carbon monoxide (CO) by 1 and the oxygen (O2) by 1. However, since the oxygen is in the form of O2, we need to multiply the entire equation by 2 to get rid of the fraction:

2CO(g) + O2(g) → 2CO2(g)

Forming the Final Chemical Equation

Now that we have balanced both equations, we can combine them to form the final chemical equation. To do this, we need to multiply the first equation by 2 and the second equation by 1:

2C(s) + O2(g) → 2CO(g)

2CO(g) + O2(g) → 2CO2(g)

Combining the Equations

Now, let's combine the two equations:

2C(s) + O2(g) → 2CO(g)

2CO(g) + O2(g) → 2CO2(g)

We can simplify this by combining the two equations:

2C(s) + 2O2(g) → 2CO2(g)

Conclusion

In this article, we have explored the process of balancing intermediate chemical equations, focusing on the given equations:

{ \begin{array}{l} C(s) + \frac{1}{2} O_2(g) \rightarrow CO(g) \\ CO(g) + \frac{1}{2} O_2(g) \rightarrow CO_2(g) \end{array} \}

By following the steps outlined in this article, we have successfully balanced the equations and formed the final chemical equation:

2C(s) + 2O2(g) → 2CO2(g)

This equation represents the complete combustion of carbon (C) in the presence of oxygen (O2) to form carbon dioxide (CO2).
