For each reaction, write the chemical formulae of the oxidized reactants in the space provided. Write the chemical formulae of the reduced reactants in the space provided.

Question

2AgNO3 + Cu -> 2Ag + Cu(NO3)2
Reduced:Cu->Cu+ +1e-
Oxidized: Ag+ + 1e- -> Ag
????????????????????

Answer 1

Oxidation is the loss of electrons. Cu goes from zero on the left to 2+ on the right. Cu ==> Cu^2+ + 2e

Reduction is the gain of electrons. Ag goes from +1 on the left to zero on the right.
Ag^+ + e ==> Ag
