    1)

    Answer: N sub 2
    Its atomic no is the lowest and also it has a triple bond.
    The values for bond lengths are:
    (A stands for Angstrom)
    a) N sub 2- 1.098 A
    b) O sub 2 -1.208 A
    c) Cl sub 2 -1.89 A
    d) Br sub 2 -2.28 A
    e) I sub 2 -2.66 A

    2)

    284 g of Psub4Osub10= 1 mole
    Therefore 14.2 g of Psub4Osub10= 14.2/ 284=0.05 mole of Psub4Osub10
    Each mole of Psub4Osub10 contains 10 atoms of oxygen= 5 moles of O sub 2
    Thus 0.05 mole of Psub4Osub10 will contain = 0.05 x 5 moles of Oxygen= 0.25 moles

    Answer: 0.25 moles of Osub2 is needed to produce 14.2 Grams 0f Psub4Osub10

    3)

    1 Faraday= charge on 1 mole of electrons
    0.060 Faraday will deposit 0.060/3= 0.020 moles of Indium (since charge = +3)

    Answer: 0.020 moles
