Final answer:
For the provided chemical reaction, 1 mole of AlCl3 is produced when 3 moles of Al react with 3 moles of NH4ClO4.
Step-by-step explanation:
The equation provided is a balanced chemical equation representing the reaction between aluminum (Al) and ammonium perchlorate (NH4ClO4).
According to the stoichiometry of the given balanced chemical equation, 3 moles of Al react with 3 moles of NH4ClO4 to produce 1 mole of Al2O3, 1 mole of AlCl3, and other products. Since every 3 moles of reactants yield 1 mole of AlCl3, we can deduce that for each mole of Al used, 1/3 mole of AlCl3 is produced.
Therefore, given that 3 moles of Al are used in the reaction, 1 mole of AlCl3 is produced.
