    7) Which would be used up first? How many grams of Cl2 will be produced?
    TiO2 + HCl = TiCl2 + Cl2 + H2O if 0.86 mole of TiO2 and 1.5 lbs of HCl react

    SOLUTION This solution is FREE courtesy of BrainMass!

    Our balanced reaction is,

    TiO2 + 4HCl ==> TiCl2 + Cl2 + 2H2O

    That is 1 mole TiO2 requires 4 moles of HCL to produce 1 mole of Cl2

    Mol wt of TiO2 = 79.9 g/mole
    Mol wt 0f HCl = 36.46 g/mole

    1 POUND = 2.2 KILOGRAMS, 1.5 lbs of HCl = 2.2*1.5 *10^3 g = 3.3*10^3 g

    That is number of moles of HCL = 3.3*10^3/36.46 = 90.51 moles.

    We have 0.86 moles of TiO2 and 90.51 moles of HCl.

    1 mole TiO2 requires 4 moles of HCL.
    Therefore, 0.86 moles of TiO2 requires 4*0.86 moles of HCl
    That is 3.44 moles of HCl.

    Therefore TiO2 will be used up first.----Ans

    Now, 1 mole TiO2 gives 1 mole of Cl2.

    Therefore 0.86 mole of TiO2 gives 0.86 moles of Cl2 = 0.86 * 70.9 g of Cl2 = 60.974 g of Cl2 ----Ans
