Introduction

Balancing chemical equations is a crucial step in chemistry that helps us understand the stoichiometry of chemical reactions. It involves adding coefficients to the reactants and products to ensure that the number of atoms of each element is the same on both sides of the equation. In this article, we will explore how to balance chemical equations using the given intermediate equations.

Understanding the Intermediate Equations

The given intermediate equations are:

{ \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} \}

These equations represent two separate reactions: the first one involves the reaction of carbon with oxygen to form carbon monoxide, while the second one involves the reaction of carbon monoxide with oxygen to form carbon dioxide.

Balancing the Equations

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

{ C(s)+\frac{1}{2} O_2(g) \rightarrow CO(g) }

To balance the carbon atoms, we need to add a coefficient of 1 in front of the CO(g) product. However, this will not balance the oxygen atoms. To balance the oxygen atoms, we need to add a coefficient of 2 in front of the O2(g) reactant.

{ C(s)+O_2(g) \rightarrow 2CO(g) }

However, this will not balance the carbon atoms. To balance the carbon atoms, we need to add a coefficient of 2 in front of the C(s) reactant.

{ 2C(s)+O_2(g) \rightarrow 2CO(g) }

Now, let's balance the second equation:

{ CO(g)+\frac{1}{2} O_2(g) \rightarrow CO_2(g) }

To balance the carbon atoms, we need to add a coefficient of 1 in front of the CO2(g) product. However, this will not balance the oxygen atoms. To balance the oxygen atoms, we need to add a coefficient of 2 in front of the O2(g) reactant.

{ CO(g)+O_2(g) \rightarrow 2CO_2(g) }

However, this will not balance the carbon atoms. To balance the carbon atoms, we need to add a coefficient of 2 in front of the CO(g) reactant.

{ 2CO(g)+O_2(g) \rightarrow 2CO_2(g) }

Combining the Equations

Now that we have balanced the individual 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.

{ 4C(s)+2O_2(g) \rightarrow 4CO(g) }

{ 2CO(g)+O_2(g) \rightarrow 2CO_2(g) }

Now, we can combine the two equations by adding them together.

{ 4C(s)+3O_2(g) \rightarrow 4CO(g)+2CO_2(g) }

Conclusion

Balancing chemical equations is a crucial step in chemistry that helps us understand the stoichiometry of chemical reactions. By following the steps outlined in this article, we can balance chemical equations using the given intermediate equations. The final balanced equation is:

{ 4C(s)+3O_2(g) \rightarrow 4CO(g)+2CO_2(g) }

This equation represents the complete combustion of carbon to form carbon dioxide.
