I think the answer is <span>PCl5 + 4H2O → 5HCl + H3PO4
</span>
The volume in liters of Hydrogen gas = 49.28 L

Further explanation
</h3>
The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products
Reaction
2 Al (s) + 6 HCl (aq) → 2 AlCl₃ (aq) + 3 H₂ (g)
mol Al :

mol H₂ :

At STP, 1 mol =22.4 L
so the volume of hydrogen :
