Hello!
The particles in a<span> gas </span>have<span> the most energy </span>and are<span> free to move around </span>and<span> so spread out rapidly. Gases do </span>not have a<span> definite </span>shape<span> or volume </span>and expand to fill<span> the entire</span>container<span>. Thus, as the temperature of matter increases, </span>its<span> density decreases.

Have a nice day
The balanced equation for the above reaction is
2Al + 6H₂O ---> 2Al(OH)₃ + 3H₂
stoichiometry of Al to H₂ is 2:3
number of Al moles reacted - 78.33 g / 27 g/mol = 2.901 mol
according to molar ratio
2 mol of Al forms - 3 mol of H₂
therefore 2.901 mol of Al - forms 3/2 x 2.901 = 4.352 mol
molar volume states that 1 mol of any gas occupies a volume of 22.4 L at STP
if 1 mol occupies 22.4 L
then 4.352 mol occupies - 22.4 L/mol x 4.352 mol = 97.48 L
volume occupied by H₂ is 97.48 L
