For each pair of reactants, if a reaction does occur, write a balanced molecular equation (ME) and a balanced net ionic equation (NIE) for the reaction, and indicate what the spectator ions are. Inlude phase labels for all reactant and product species. If no reaction occurs, write NR.

A. NaOH (aq) + Fe (NO​3)2 ​(aq)

B. KClO​4 (aq) + Mg(NO​3)​2 ​(aq)

C. Zn (s) +   HBr (aq)

D. Al (s) + HNO​3 (aq)

E. (CH​3)​2NH (aq) + H​2O (l)

Solutions

Expert Solution

A 3 NaOH(aq) + Fe(NO3)3(aq)----3 NaNO3(aq) + Fe(OH)3(s) - moelcular equation

3 Na+ (aq) + 3 OH- (aq) + Fe3+(aq) + 3 NO3-(aq) ---- 3 Na+ (aq) + 3 NO3-(aq) + Fe(OH)3(s) - total ionic equation

3 OH- (aq) + Fe3+(aq) Fe(OH)3(s) -Net ionic equation

B NR

C Zn(s) + 2 HBr(aq)---H2 + ZnBr2moelcular equation

Zn(s) + 2H+(aq) +2Br-(aq)---H2(g) + Zn2+(aq) + 2Br-(aq) total ionic equation

Zn(s) + 2H+(aq)---- H2(g) + Zn2+(aq) net ionic

D 2Al(s) + 6HNO3(aq)----->2Al(NO3)3(aq) + 3H2(g)-moelcular equation

6H+(aq) + 6NO3-(aq) + 2Al(s) --> 2Al3+(aq) + 6NO3-(aq) + 3H2 (l) -Complete ionic equation:

6H+(aq) + 2Al (s) --> 2Al3+(q) + 3H2 (l)-Net ionic equation
