Question

Which is thermal decomposition reaction
2h2o=2h2+O2
2agcl=2ag+cl2
Znco3=zno+CO2
H2=cl2+2hcl

Answer 1

2h2o=2h2+o2 is the answer bro

Answer 2

ZnCo3→ZnO+CO2 is the thermal decomposition reaction

Explanation:

because decomposition of h2O is electrolytic decomposition reaction...

decomposition of AgCl is photolytic decomposition...
