I found the attached image with the same statement of your question and think it may be very useful for you that I use it to show how to answer this question (furthermore I think it may be the same reaction that you forgot to include).
As you can see, there are one image on the left side and other image on hte right side of the figure.
Those images contains drawings that represent molecules and a legend that permit you to distinguish the kind of atoms in each molecule.
Using that, you can indicate the chemical reaction as the transformation of the molecules on the left side onto the molecules on the right side:
Left side:
3 molecules of CH4 and 3 molecules of N2Cl4
Right side:
3 molecules of CCl4, 3 molecules of N2 and 6 molecules of H2
That is represented as:
3CH4 + 3 N2Cl4 -----> 3 CCl4 + 3N2 + 6H2
And that is the balanced chemical equation for the reaction shown in the figured attached.
I hope this is useful for you..

This is an incomplete question, here is a complete question.
Hydrogen chloride and oxygen react to form water and chlorine, like this:
Use this chemical equation to answer the questions in the table below.
Suppose 155. mmol of HCl and 38.8 mmol of O₂ are added to an empty flask. How much HCl will be in the flask at equilibrium?
(1) None.
(2) Some, but less than 155. mmol,
(3) 155. mmol,
(4) More than 155. mmol,
Answer : The correct option is, (1) None
Explanation :
The given balanced chemical reaction is:
From the balanced chemical reaction, we conclude that
As, 4 mmole of HCl react with 1 mmoles of
So, 155. mmole of HCl react with mmoles of
That means, is excess reagent and
is a limiting reagent. All the moles of HCl will consume.
Hence, the correct option is, None.
