When zinc metal is placed into a copper(II) nitrate solution, a single-displacement reaction occurs. Which of the following is a balanced equation that describes this reaction?
A) 2Zn(s) + Cu(NO3) 2(aq) → 2Zn(NO3) 2(aq) + Cu(s)
B) Zn(s) + Cu(NO3) 2(aq) → ZnNO3(aq) + CuNO3(aq)
C) Zn(s) + Cu2NO3(aq) → ZnNO3(aq) + Cu(aq)
D) Zn(s) + Cu(NO3) 2(aq) → Zn(NO3) 2(aq) + Cu(s)
E) Zn(s) + Cu2NO3(aq) → ZnNO3(aq) + 2Cu(aq)
