Answer:

All matter contains heat energy. Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases.

What is the volume in liters of hydrogen gas that would be produced by the reaction of 40.0 g of Al with excess HCl at STP accor
DaniilM [7]

The volume in liters of Hydrogen gas = 49.28 L

<h3>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 :

\tt mol=\dfrac{mass}{Ar}=\dfrac{40}{27}=1.481

mol  H₂ :

\tt \dfrac{3}{2}\times 1.481=2.2

At STP, 1 mol =22.4 L

so the volume of hydrogen :

\tt 2.2 \times 22.4=49.28~L
