What is the Final Chemical Equation from the Given Intermediate Chemical Equations?

Understanding the Intermediate Chemical Equations

In chemistry, intermediate chemical equations are used to describe the steps involved in a chemical reaction. These equations are essential in understanding the overall reaction and the changes that occur during the process. In this article, we will explore two intermediate chemical equations and determine the final chemical equation that results from them.

The First Intermediate Chemical Equation

The first intermediate chemical equation is:

P_4O_6(s) → P_4(s) + 3O_2(g)

In this equation, phosphorus pentoxide (P_4O_6) decomposes into phosphorus (P_4) and oxygen gas (O_2). This reaction is a decomposition reaction, where a single compound breaks down into two or more simpler substances.

The Second Intermediate Chemical Equation

The second intermediate chemical equation is:

P_4(s) + 5O_2(g) → P_4O_{10}(s)

In this equation, phosphorus (P_4) reacts with oxygen gas (O_2) to form phosphorus pentoxide (P_4O_{10}). This reaction is a synthesis reaction, where two or more substances combine to form a more complex substance.

Determining the Final Chemical Equation

To determine the final chemical equation, we need to combine the two intermediate chemical equations. We can do this by reversing the second equation and then combining it with the first equation.

Reversing the Second Equation

To reverse the second equation, we need to change the direction of the reaction. This means that the products become the reactants, and the reactants become the products. The reversed equation is:

P_4O_{10}(s) → P_4(s) + 5O_2(g)

Combining the Two Equations

Now that we have the reversed second equation, we can combine it with the first equation. We can do this by adding the two equations together, making sure to cancel out any common terms.

P_4O_6(s) → P_4(s) + 3O_2(g)

P_4O_{10}(s) → P_4(s) + 5O_2(g)

When we add these two equations together, we get:

P_4O_6(s) + 2O_2(g) → P_4O_{10}(s)

The Final Chemical Equation

The final chemical equation is:

P_4O_6(s) + 2O_2(g) → P_4O_{10}(s)

This equation represents the overall reaction that occurs when phosphorus pentoxide (P_4O_6) reacts with oxygen gas (O_2) to form phosphorus pentoxide (P_4O_{10}).

Conclusion

In conclusion, by combining the two intermediate chemical equations, we were able to determine the final chemical equation. This equation represents the overall reaction that occurs when phosphorus pentoxide (P_4O_6) reacts with oxygen gas (O_2) to form phosphorus pentoxide (P_4O_{10}). Understanding intermediate chemical equations is essential in chemistry, as it allows us to break down complex reactions into simpler steps and understand the changes that occur during the process.
