306699 Assertion :
3 moles of azide ion and 1 mole of nitride ion contain same amount of charge.
Reason :
1 mole of azide ion and 1 mole of nitride ion have equal number of nitrogen atoms.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.

306700 The molecular formula of a commercial resin used for exchanging ions in water softening is \({{\rm{C}}_{\rm{8}}}{{\rm{H}}_{\rm{7}}}{\rm{SO}}_{\rm{3}}^{\rm{ - }}{\rm{N}}{{\rm{a}}^{\rm{ + }}}\) (Mol. wt. 206). What would be the maximum uptake of \({\rm{C}}{{\rm{a}}^{{\rm{2 + }}}}\) ions by the resin when expressed in mole per gram resin?

1 \(\frac{{\rm{2}}}{{{\rm{309}}}}\)
2 \(\frac{{\rm{1}}}{{{\rm{412}}}}\)
3 \(\frac{{\rm{1}}}{{{\rm{103}}}}\)
