Balance the following reactions, all of which were performed in acidic soln.?

Question

Underline the reducing agent and draw a box around the oxidizing agent.

Hg(s) + (NO3)- (aq) + Cl-(aq) -->Hg(Cl4)2- (aq) + NO(g) +S(s)


I2(s) + S2(O3)2- (aq) --> I-(aq) +S4(O6)2- (aq)

thanks

Answer 1

Hg(s) + (NO3)- (aq) + Cl-(aq) -->Hg(Cl4)2- (aq) + NO(g) +S(s)
Issue 1: Hg is not a solid (above -38.83°C)
Issue2: Where comes sulpher S?
Please check your source of the problem.

I2(s) + S2(O3)2- (aq) --> I-(aq) +S4(O6)2- (aq)
I2(s) + 2S2O3(2-) (aq) ==> 2I-(aq) +S4O6(2-) (aq)
