Question

give an example each for thermal decomposition and photochemical decomposition reactions write balanced equation for the same


plzzz answer it quickly

firstly give the reaction and then balanced it ​

Answer 1

Answer:

example of thermal decomposition reaction is :

CaCO3(S)→(HEAT ) CaO(s) + CaO2(g)

( it is already balanced)

example of petrochemical decomposition reaction is:

2AgCl(s)→(sunlight) 2Ag(s) + Cl2(g)

(it is already balanced)

Explanation:

Answer 2

Answer:

Hi

Explanation:

when pb (No3)2 is heated then it's product is 2 pbo + 4No + O2

pb (No3)2 ------- 2Pbo + 4No + O2

when silver bromine is kept in sunlight then it is broken down into silver and bromine .

2AgBr_sunlight__ 2Ag+ Br2
