Jason Combines The Two Intermediate Steps Shown:${ \begin{array}{l} N_2(g) + O_2(g) \longrightarrow 2 NO(g) \ 2 NO(g) + O_2(g) \longrightarrow 2 NO_2(g) \end{array} }$Which Best Describes What Jason Should Do With The Oxygen Molecules?A.
Understanding the Problem
Jason is presented with two intermediate steps in a chemical reaction, and he needs to combine them to form a single equation. The two steps are:
{ \begin{array}{l} N_2(g) + O_2(g) \longrightarrow 2 NO(g) \\ 2 NO(g) + O_2(g) \longrightarrow 2 NO_2(g) \end{array} \}
Analyzing the Equations
To combine the two equations, we need to analyze them carefully. The first equation shows the reaction of nitrogen and oxygen molecules to form nitric oxide (NO). The second equation shows the reaction of nitric oxide and oxygen molecules to form nitrogen dioxide (NO2).
Identifying the Common Component
The common component between the two equations is the oxygen molecule (O2). In the first equation, oxygen is a reactant, while in the second equation, it is a reactant as well.
Determining the Correct Course of Action
To combine the two equations, Jason needs to determine the correct course of action with the oxygen molecules. The correct answer is:
- B. Jason should cancel out the oxygen molecules from the first equation and add them to the second equation.
Explanation
When we cancel out the oxygen molecules from the first equation, we are left with:
This equation shows the reaction of nitrogen molecules to form nitric oxide. When we add the oxygen molecules from the second equation to this equation, we get:
This is the combined equation that Jason should use.
Conclusion
In conclusion, Jason should cancel out the oxygen molecules from the first equation and add them to the second equation to form a single combined equation. This requires careful analysis of the two equations and identification of the common component.
