Question

Write the balanced net ionic equation for the following (include phases):

Did I do this correctly?

NH4Cl + Na2S-->NaCl + NH3 + H2S

Balanced: 2NH4Cl + Na2S --> 2NaCl + 2NH3 + H2S

Ionic: 2NH4+ + 2Cl- + 2Na+ + S- ---> 2Na+ + 2Cl- + 2NH3+ + 2H+ + S-

Net ionic: 2NH4+ (aq) ---> 2NH3+ (aq) + 2H+ (l)

We were asked to predict the observations that could be made in an experiment for particular solutions and to determine if they were precipitate, gas, heat or no reaction.

For example, some of the the combinations given are NiCl2 and Ba(OH)2 as well as NiCl2 and NH4Br. How can I predict what its reaction will be?

Explanation / Answer

NH4Cl + Na2S-->NaCl(S) + NH3(g) + H2S(g)

Balanced: 2NH4Cl + Na2S --> 2NaCl + 2NH3 + H2S

Ionic: 2NH4+ + 2Cl- + 2Na+ + S- ---> 2Na+ + 2Cl- + 2NH3+ + 2H+ + S-

Net ionic: 2NH4+ (aq) ---> 2NH3+ (aq) + 2H+ (l)
