  • When you add the negative ion to a positive ion (like Na+) in an ionic compound, the convention is the negative ion is listed last. Physically, the bond is with the oxygen atom, since the Cl ion is actually in a +1 oxidation state, leaving one of oxygen’s 2 negative valences to be filled. So the Na+ will bond with the oxygen, not with the chlorine. So it is a tad more representative of the physical structure to put the oxygen first in the OCl- ion.

    B. The oxygen atom accepts the proton. The oxidation number of O is -2, meaning that there are two unshared electrons in the valence shell; In the ClO- ion, one of these is shared with the Cl- ion, leaving an unshared electron on the oxygen atom, which is what the hydrogen atom shares its electron with, becoming the proton accepted by the O atom.

  • Step:1 convert the mol of NH3 into grams which will give you 87.95 grams of Ammonia, NH3. Step:2 Our Equation is: 2NH3 + OCl- –> N2H4 + Cl- + H2O so in order to find the moles for Hydrazine, N2H4, dimensional analysis is the next action. ?mol N2H4 = 87.75 g (1 mol / 15.0 g NH3) * (1 mol N2H4 / 2 mol NH3) = 2.93 mol N2H4. Step 3: We are almost there. Since the reaction has a 78.2 % yield, the final step would be: (2.93 * 78.2) / 100 = 2.29 mol N2H4.

  • the correct ion is OCl- because Cl takes one electron from oxygen
