Question

Write one example for each of decomposition reaction?​

Answer 1

Answer:

Example of decomposition reaction:-2HgO---------2Hg+O2.

#Thermal decomposition-CaCO3------CaO+CO2.

#Photo chemical decomposition-2AgCl+2Ag+Cl2.

#Electrolysis-2H2O----–--2H2 +O2.

I hope it's well please mark me as brainlist...

Answer 2

Answer:

There are three types of decomposition reactions. They're:

1) Thermolytic decomposition (by means of heat).

Eg- NaHCO3 ----∆------> Na2CO3 + CO2 + H2O

(∆ stands for heat)

2) Photolytic decomposition (by means of light).

Eg- AgCl ----in presence of sunlight----> Ag + Cl2

3) Electrolytic decomposition (by means of electrolysis)

Eg- NaCl ----electrolysis----> Na + Cl
