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 chemical equations.
Understanding the Intermediate Chemical Equations
The given intermediate chemical 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 (C) with oxygen (O2) to form carbon monoxide (CO), while the second one involves the reaction of carbon monoxide (CO) with oxygen (O2) to form carbon dioxide (CO2).
Balancing the First Equation
To balance the first equation, 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 counting the number of atoms of each element on both sides of the equation:
Reactants: C (1), O2 (0.5) Products: CO (1), O2 (0.5)
To balance the equation, we need to add a coefficient of 2 to the reactant O2 and a coefficient of 2 to the product CO. This will ensure that the number of atoms of each element is the same on both sides of the equation.
Balancing the Second Equation
To balance the second equation, 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 counting the number of atoms of each element on both sides of the equation:
Reactants: CO (1), O2 (0.5) Products: CO2 (1), O2 (0.5)
To balance the equation, we need to add a coefficient of 2 to the reactant O2 and a coefficient of 2 to the product CO2. This will ensure that the number of atoms of each element is the same on both sides of the equation.
Forming the Final Chemical Equation
Now that we have balanced the two intermediate chemical equations, we can form the final chemical equation by combining the two equations. To do this, we need to multiply the first equation by 2 and the second equation by 1.
Final Chemical Equation
The final chemical equation is:
{ \begin{array}{l} 2C(s) + O_2(g) \rightarrow 2CO(g) \\ 2CO(g) + O_2(g) \rightarrow 2CO_2(g) \end{array} \}
Combining the two equations, we get:
{ \begin{array}{l} 2C(s) + O_2(g) \rightarrow 2CO(g) \\ 2CO(g) + O_2(g) \rightarrow 2CO_2(g) \end{array} \}
{ \begin{array}{l} 2C(s) + 2O_2(g) \rightarrow 2CO_2(g) \end{array} \}
