Reactants Rxn: Ox(1) + Red(2) + other -> Red(1) + Ox(2) + other Aluminum metal is added to a ZnSO4 solution Chromium metal is placed in hydrochloric acid A copper wire is added to nitric acid Chromium metal is added to water A silver wire is placed into an acidified solution of KMnO4

Explanation / Answer

2 Al (s) + 3 ZnSO4 (aq) --------->3 Zn(s) + Al2(SO4)3(aq)

Cr (s) +2 HCl(aq) --------> CrCl2 (aq) + H2(g)

3Cu(s) + 8HNO3 (aq) -------------> 3Cu(NO3)2 + 2NO +4 H2O

Cr + H2o -----> No reaction

Ag + KMNO4 -------> No reaction
