This is not, in my school you have the choice whether or not to send them and what I would do is talk to your guidance counselor and ask them questions about it and how to undo the process.
Answer is Nitrogen. Nitrogen is the most abundant gas and for Second is Oxygen
The number of molecules of NO₂ that can be obtained when 2 molecules of NO react is 2 molecules
<h3>Balanced equation</h3>
We'll begin by writing the balanced equation for the reaction. This is given below:
NO + O₂ —> NO₂
There are 3 atoms of O on the left side and 2 atoms on the right side. It can be balanced by writing 2 before NO and NO₂ as shown below
2NO + O₂ —> 2NO₂
Now, the equation is balanced
From the balanced equation above,
We can see that 2 molecules of NO will react to produce 2 molecules of NO₂.
Thus, we can conclude that 2 molecules of NO₂ will be obtained from the reaction.

Answer:
<u><em>Maria, 600 meters.</em></u>
Explanation:
0.5 kilometers in meters is 500 meters. Maria ran 600 meters, and Juan ran 500.
600 is greater than 500, so 500 is the answer.
Hope this helped! :)
