PbCl2+ AgNO3>Pb(NO3)2+ AgCl

Decomposition

Synthesis

Double displacement

Exothermic

Option C

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 has a positive ion and negative ion

Like wise the second compound has a positive ion and negative ion

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

This is example of double displacement reaction.

Option C is correct

i'm assuming that the correct answer is indeed the first one/ "a"..

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42
