Question

8 pts 25. Aluminum metal (0.100 mol) and a volume of aqueous hydrochloric acid that contains 0.500 mol of HCl are combined and react to completion. How many liters of hydrogen gas, measured at STP are produced? Al(s) + HCl(aq) - AICI3(aq) + H2(g) (unbalanced) 4.48 L of H2 5.60 L of H2 224 L of H2 3.36 L of H2 6.72 L of H2

Answer 1

The answer is 3.36 L of H2. I hope the solution is helpful to you.

The is. guien reaction Al ts) + Hellap) - Alle aj + 4 lg) is Balanced reaction Alat 6 Heecal) Alce + 34 lg) from the reaction 2 males of Al +. a moles of the quien 3 males y Ma is present required in bees amount i i 2 males of Al give - 3 moles of Kg * 0.100 moles of Alque - 3X0-100 moles 2 M₂ At STP: - (according to male concept) volume of 1 mol of Ha gas = 22042 d. volume of (3 0.1) mole of a gas = 22.4x0,3 = 3.36.
