Copper metal reacts with silver nitrate to produce silver metal and copper (II) nitrate. the correct equation for this reaction is:
A: Cu + SiN—> Si + Cu2N

B: 2Cu + AgNO3–> Ag +
Cu(NO3)2

C: Cu + 2 AgNO3–> Ag + Cu(NO3)2

D:Cu + AgNO3–> Ag + CuNO3

Cu    +    2AgNO₃  →   2Ag    +    Cu(NO₃)₂

Explanation:

The reactants are:

         Copper metal  = Cu

         Silver nitrate  = AgNO₃

The products are:

          Silver metal  = Ag

           Copper (II) nitrate  = Cu(NO₃)₂

So, the reaction equation is given as;

      Cu    +    2AgNO₃  →   2Ag    +    Cu(NO₃)₂

This is a single displacement reaction
