Reactants Rxn: Ox(1) + Red(2) + other -> Red(1) + Ox(2) + other Manganese metal is added to a MgSO4 solution none Copper metal is added to hydrochloric acid none A silver wire is added to nitric acid NO_34- + 3Ag + 4H4+ -> NO + 3Ag + 2H_20 Sodium metal is added to water 2Na + 2H2O -> 2Na+ + 2OH^- + H2 A silver wire is placed into an acidified solution of KMnO4 Mn0411- + 5Ag + 8H^1+ -> Mn^+2 + 5 Ag^+ + 4H:

Answer 1

1. Mn added to MgSO4 solution

Mn + SO4^^2- - Mn2^{^+} + SO4^{^2_}

2. copper metal to HCl

Cu + 2 Cl^^- - CuCl2
