Answer:
The products react to reform the original reactants
E.g. Haber process of ammonia production
According to Avogadro's law, the two gases will have equal number of molecules.
<h3>Avogadro's law </h3>
From the question, we are to determine how the two gases would compare according to Avogadro's law
First, we will state the Avogadro's law
<em>Avogadro's law</em> states that "equal volume of all gases at the <u>same temperature and pressure</u> contain the same number of molecules"
Now, from the given information
We have 2 liters of hydrogen gas and 2 liters of oxygen gas at the <u>same temperature and pressure</u>
According to Avogadro's law, gases that are equal in volume and are at the same temperature and pressure will have equal number of molecules.
Hence, according to Avogadro's law, the two gases will have equal number of molecules.

Answer : The volume of
is 14.784 L.
Solution : Given,
Mass of Aluminium = 6 g
Molar mass of Aluminium = 27 g/mole
First we have to calculate the moles of aluminium.
Moles of Al = 
The given balanced reaction is,

From the reaction, we conclude that
2 moles of Al react with the 6 moles of 
0.22 moles of Al react with
of 
At STP, 1 mole contains 22.4 L volume
As, 1 mole of
contains 22.4 L volume of 
0.66 moles of
contains
volume of 
Therefore, the volume of
is 14.784 L.
