Question

What are the molecular equation, total ionic equation, and net ionic equation for the reactions of:

a.) tin and silver nitrate

b.) tin and zinc nitrate

For the following reactions... what is the substance oxidized and reduced? What are the oxidizing agent and reducing agent?

a.) Mg + CuSO4 --->

b.) Zn + HCl -->

Answer 1

a)

molecular equation

Sn(s) + 2AgNO3(aq) =====> Sn(NO3)2(aq) + 2 Ag(s)

total ionic equation

Sn(s) + 2Ag+ (aq) 2NO₃^-(aq) =====> Sn+ (aq) + 2NO₃(aq) + 2 Ag(s)

net ionic equation is

Sn(s) + 2Ag+(aq) => Sn+2(aq) + 2 Ag(s)

partB

molecular equation

Sn (s) + Zn (NO3)2 (aq) ------> Sn(NO3)2 (aq) + Zn (s)

total ionic equation

Sn (s) + Zn²⁺ (aq) + 2 NO3^- ----> Sn²⁺ (aq) + 2 NO3^- + Zn (s)

net ionic equation

Sn (s) + Zn²⁺ (aq) --->   Sn²⁺ (aq) +  Zn (s)

a)

Mg + CuSO4 ---> MgSO4 + Cu

oxidisen agent is CuSO4

reducing agent is Mg

b)

Zn + 2HCl --> ZnCl2 + H2

oxidising agent is H+

reducing agent is Zn
