Introduction
Chemical equations are a fundamental concept in chemistry, used to describe the transformation of one or more substances into another. In this article, we will explore the process of combining intermediate chemical equations to obtain the overall chemical equation. We will use the given intermediate chemical equations as an example to illustrate this process.
Understanding Intermediate Chemical Equations
Intermediate chemical equations are a series of chemical reactions that occur in a specific order to produce a desired product. These equations are often used to describe complex chemical reactions that involve multiple steps. In the given example, we have two intermediate chemical equations:
{ \begin{array}{l} CH_4(g) + 2 O_2(g) \rightarrow CO_2(g) + 2 H_2O(g) \\ 2 H_2O(g) \rightarrow 2 H_2O(l) \end{array} \}
Step 1: Identify the Overall Chemical Equation
To combine the intermediate chemical equations, we need to identify the overall chemical equation. The overall chemical equation is the final product of the intermediate chemical reactions. In this case, we can see that the first intermediate equation produces CO2 and H2O, while the second intermediate equation produces H2O in the liquid state.
Step 2: Eliminate the Intermediate Products
To obtain the overall chemical equation, we need to eliminate the intermediate products. In this case, we can eliminate the H2O(g) produced in the first intermediate equation, as it is not present in the final product.
Step 3: Combine the Remaining Reactants and Products
After eliminating the intermediate products, we are left with the reactants and products of the overall chemical equation. In this case, we have CH4(g) and O2(g) as the reactants, and CO2(g) and H2O(l) as the products.
Step 4: Write the Overall Chemical Equation
Now that we have identified the reactants and products of the overall chemical equation, we can write the final equation. The overall chemical equation is:
