    To react with 0.5 moles of Zn 1 mole of HCl is required

    Explanation:

    Given dа ta:

    Number of moles of Zn = 0.50 mol

    Number of moles of HCl = ?

    Chemical equation:

    Zn + 2HCl → H₂ + ZnCl₂

    Now we will compare the moles of Zn and HCl through balance chemical equation.

    Zn : HCl

    1 : 2

    0.50 : 2*0.5 = 1 mol

    In order to react with 0.5 moles of zinc 1 mole of HCl is required.
