How many molecules of no2 can be formed using 2 molecules of no
MAXImum [283]

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.
