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 formation of nitrogen monoxide (NO) from nitrogen gas (N2) and oxygen gas (O2). The second equation shows the formation of nitrogen dioxide (NO2) from nitrogen monoxide (NO) and oxygen gas (O2).

Identifying the Common Component

The common component between the two equations is oxygen gas (O2). In the first equation, one oxygen molecule is consumed, while in the second equation, one oxygen molecule is also consumed. Therefore, we can conclude that oxygen molecules are consumed in both equations.

Determining the Correct Answer

Based on the analysis, we can determine that Jason should combine the two equations by canceling out the oxygen molecules. This means that the correct answer is:

  • B. Cancel out the oxygen molecules

Explanation

When combining the two equations, we need to cancel out the oxygen molecules that are consumed in both equations. This will result in a single equation that shows the formation of nitrogen dioxide (NO2) from nitrogen gas (N2) and oxygen gas (O2).

The Combined Equation

The combined equation is:

N2(g)+2O2(g)⟶2NO2(g){ N_2(g) + 2 O_2(g) \longrightarrow 2 NO_2(g) }

Conclusion

In conclusion, Jason should combine the two intermediate steps by canceling out the oxygen molecules. This will result in a single equation that shows the formation of nitrogen dioxide (NO2) from nitrogen gas (N2) and oxygen gas (O2).

Key Takeaways

  • When combining chemical equations, we need to analyze them carefully to identify the common components.
  • Oxygen molecules are consumed in both equations, so we can cancel them out to form a single equation.
  • The combined equation shows the formation of nitrogen dioxide (NO2) from nitrogen gas (N2) and oxygen gas (O2).

Additional Tips

  • When combining chemical equations, make sure to balance the number of atoms of each element on both sides of the equation.
  • Use the law of conservation of mass to ensure that the number of atoms of each element is conserved in the combined equation.
  • Practice combining chemical equations to develop your skills and become more confident in your ability to solve problems.
