please help me with these reactions...

CONCLUSIONS For each test tube, write the balanced molecular reaction. Also write the total ionic reaction and net ionic reaction. If no reaction occurred, simply write "NO REACTION" in the space for the molecular reaction 1. HINT: In reactions 5 & 6 use the +2 oxidation state for Cu in products if any reaction occurs In reactions 7 & 8 use the +2 oxidation state of Fe in any products. 1 ?Zn + Fe(NO3)3(c) ? ?Zn(N03), molecular reaction te) Fu net ionic reaction Fe 2n 2 molecular reaction Zn+MgSO4(aq) ?Mg+ (S ) + Zna?50L(an)-7 Znsoud total ionic reaction M? net ionic reaction Mg(s) molecular reaction M) ts ta?"(an)-?Mg2+ (aa)+Zn (s) 3 Zn Al(NO3)3 (aa) ? + hurac4.,~ total ionic reaction No rt.ac.4-10? net ionic reaction 4 moleculiar reaction 3 Mg total ionic reaction eH g (s) AI(NO)) AI (a Al (aa) t (rola (aq)? ?

Explanation / Answer

1.

ME: 3 Zn (s) + 2 Fe(NO3)3 (aq.) --------> 3 Zn(NO3)2 (aq.) + 2 Fe (s)

IE : 3 Zn (s) + 2 Fe3+ (aq.) + 6 NO3- (aq.) ---> 3 Zn2+ (aq.) + 6 NO3- (aq.) + 2 Fe (s)
NIE : 3 Zn (s) + 2 Fe3+ (aq.) ----------> 3 Zn2+ (aq.) + 2 Fe (s)

2.

ME : Zn (s) + MgSO4 (aq.) ----------> ZnSO4 (aq.) + Mg (s)
IE : Zn (s) + Mg2+ (aq.) + SO42- (aq.) ------> Zn2+ (aq.) + SO42- (aq.) + Mg (s)

NIE : Zn (s) + Mg2+ (aq.) ---------> Zn2+ (aq.) + Mg (s)

3.

ME: 3 Zn (s) + 2 Al(NO3)3 (aq.) --------> 3 Zn(NO3)2 (aq.) + 2 Al (s)

IE : 3 Zn (s) + 2 Al3+ (aq.) + 6 NO3- (aq.) ---> 3 Zn2+ (aq.) + 6 NO3- (aq.) + 2 Al (s)
NIE : 3 Zn (s) + 2 Al3+ (aq.) ----------> 3 Zn2+ (aq.) + 2 Al (s)

4.

ME: 3 Mg (s) + 2 Al(NO3)3 (aq.) --------> 3 Mg(NO3)2 (aq.) + 2 Al (s)

IE : 3 Mg (s) + 2 Al3+ (aq.) + 6 NO3- (aq.) ---> 3 Mg2+ (aq.) + 6 NO3- (aq.) + 2 Al (s)
NIE : 3 Mg (s) + 2 Al3+ (aq.) ----------> 3 Mg2+ (aq.) + 2 Al (s)

5.

ME : Cu (s) + H2SO4 (aq.) -----------> CuSO4 (aq.) + H2 (g)

IE : Cu (s) + 2 H+ (aq.) + SO42- (aq.) -------> Cu2+ (aq.) + SO42- (aq.) + H2 (g)
NIE : Cu (s) + 2 H+ (aq.) -----------> Cu2+ (aq.) + H2 (g)
6.

ME : Cu (s) + 2 AgNO3 (aq.) ---------> Cu(NO3)2 (aq.) + 2 Ag (s)
IE : Cu (s) + 2 Ag+ (aq.) + 2 NO3- (aq.) ---> Cu2+ (aq.) + 2 NO3- (aq.) + 2 Ag (s)
NIE : Cu (s) + 2 Ag+ (aq.) ----------> Cu2+ (aq.) + 2 Ag (s)
7.

NO REACTION

8.

ME : Fe (s) + H2SO4 (aq.) -----------> FeSO4 (aq.) + H2 (g)

IE : Fe (s) + 2 H+ (aq.) + SO42- (aq.) -------> Fe2+ (aq.) + SO42- (aq.) + H2 (g)
NIE : Fe (s) + 2 H+ (aq.) -----------> Fe2+ (aq.) + H2 (g)
