“Aerated” concrete bricks are widely used building materials. They are obtained by mixing gas forming additives with a moist mixture of lime, cement, and possibly sand. Industrially, the following reaction is important:
2 Al(s) + 3 Ca(OH)₂(s) + 6 H₂O(ℓ) → 3 CaO ∙ Al₂O₃ ∙ 6 H₂O(s) + 3 H₂(g)
Assume the mixture of reactants contains 0.56 g of Al (as well as excess calcium hydroxide and water) for each brick. What volume of hydrogen gas do you expect at 26°C and a pressure of 745 mm Hg?
