Question

PbCl2+ AgNO3------>Pb(NO3)2+ AgCl

Decomposition

Synthesis

Double displacement

Exothermic

Answer 1

Option C

Step-by-step explanation:

A double displacement reaction is the one in which two chemical compounds having a cation and anion in each exchange their positive and negative ions thereby forming new compounds or products.

Here,

The first compound
`PbCl_2` has a positive ion
`Pb` and negative ion
`Cl^-`

Like wise the second compound
`Ag(NO_3)` has a positive ion
`Ag` and negative ion
`NO_3`

The new compounds will be formed when cation of one compound attaches with the anion of other compound. Hence the new compounds are

`Pb(NO_3)_2`

`AgCl`

This is example of double displacement reaction.

Option C is correct
