Problem

Consider the diagram below, which represents two steps in an overall reaction. The red spheres are oxygen, the blue ones nitrogen, and the green ones fluorine.
First reaction: NO2 plus F2 go to FNO2 plus F. Second reaction: NO2 plus F goes to FNO2.

Write the equation for the overall reaction.

Solution

We're asked to write the equation for the overall reaction based on the given diagram.


We know that:

  • red spheres are oxygen, O
  • blue spheres are nitrogen, N 
  • green ones are fluorine, F


To do so, we need to do these steps: 


Step 1.  Write the equation for each given reaction (two steps) based on the diagram

Step 2. Write the equation for the overall reaction by canceling out intermediates


Recall that intermediates are substances that are found on both sides of a chemical equation
