Answer:

Explanation:
Hello,
In this case, we first apply the ideal gas equation to compute the moles of produced chlorine:

Then, by considering the given reaction, applying the stoichiometry, that shows a 1 to 1 relationship between chlorine and manganese dioxide, we find:

Best regards.
Gas, as the particles have the most energy, and thus move the most.
The balanced equation is as below
2 N₂O₃ → 2N₂ + 3O₂
<u><em> Explanation</em></u>
According to the law of mass conservation the number of atoms in reactants side must be equal the to the number of atoms in products side.
Therefore the balanced reaction above is balanced since the number of atoms in reactants side are equal to number of atoms in products side.
For there 4 atoms of N in reactants side and 4 in products side.
