    Answer:

    If you hace 4 moles of CaCl₂, you can make 8 moles of HCl.

    Explanation:

    The balanced equation is

    CaCl₂ + 2 H₂O → Ca(OH)₂ + 2 HCl

    By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction) , the following amounts of each compound participate in the reaction:

    • CaCl₂: 1 mole
    • H₂O: 2 moles
    • Ca(OH)₂: 1 mole
    • HCl: 2 moles

    Then you can apply the following rule of three: if by stoichiometry 1 mole of CaCl₂ forms 2 moles of HCl, 4 moles of CaCl₂ form how many moles of HCl?

    moles of HCl=\frac{4 moles of CaCl_{2}*2 moles of HCl }{1mole of CaCl_{2}}

    moles of HCl= 8

    If you hace 4 moles of CaCl₂, you can make 8 moles of HCl.
