I need to write the NIE for these:(adsbygoogle = window.adsbygoogle || []).push({});

1. "0.1M lead nitrate, [itex]Pb\left(NO_3\right)_2[/itex] and 1.0M sodium chloride, [itex]NaCl[/itex]."

2. "6M sodium hydroxide, [itex]NaOH[/itex], is added to 0.5M ammonium chloride, [itex]NH_4Cl[/itex]."

For the first one, I set up the following equation (not balanced):

[itex]Pb\left(NO_3\right)_2+NaCl\rightarrow PbCl+NaNO_3[/itex]

...however, I cannot seem to balance this. If I make it [itex]2NaNO_3[/itex], then I have to do the same to [itex]NaCl[/itex] on the other side, which in turn makes me have to do the same thing to [itex]Pb\left(NO_3\right)_2[/itex], and I keep going around in circles. Does anyone have a suggestion on this?

On the second problem, I set it up like this:

[itex]NaOH+NH_4Cl\rightarrow NaCl+NH_4OH[/itex]

Would I be correct to say that [itex]NH_4OH[/itex]isn'ta strong electrolyte (because only NaOH, KOH, Ba(OH)_{2}, and Ca(OH)_{2}are)? And as far as [itex]NH_4Cl[/itex] goes, I cannot tell if it is a strong electrolyte or not. For this molecule, how would I determine this?

Thanks a lot for your help.
