Zn(NO3)2 + 2Ag ---> Zn + 2AgNO3
The equation is as follows: CH2OH(CHOH)4CHO(aq) + 2Ag(NH3)2+(aq) + 3OH- (aq) → (Glucose) (Tollen's Reagent, Ammoniacal Silver Nitrate) 2Ag(s) + CH2OH(CHOH)4COO-(aq) + 4NH3(aq) + 2H2O(l) (Silver metal, (Gluconic acid) which forms silver mirror)
This is a 'Sngle Displacement' reaction ( A + BC --> AC + B
Zn(s) + 2AgNO3(aq) --> Zn(NO3)2(aq) + 2Ag(s) is a single displacement reaction. It is also called a single replacement reaction. As you can see, the zinc displaced, or replaced, the silver in the silver nitrate solution.

2Ag + Cl2 --> 2AgCl
2Ag + S --> Ag2S
Zn + Ag2S -> 2Ag + ZnS

2Ag + ZnSO4 = Ag2SO4 + Zn
Zn(NO3)2 + 2Ag ---> Zn + 2AgNO3
It turns grey in colour i.e., 2AgCl ------> 2Ag+Cl2
