Oxidation number of each element on both sides is same.

Q. Which is not a redox reaction?

$B a O_{2} + H_{2} S O_{4} \to B a S O_{4} + H_{2} O_{2}$

$2 B a O + O_{2} \to 2 B a O_{2}$

$4 K Cl O_{3} \to 4 K Cl O_{2} + 2 O_{2}$

$S O_{2} + 2 H_{2} S \to 2 H_{2} O + 3 S$

Oxidation number of each element on both sides is same.

Q. Which is not a redox reaction?

BaO2​+H2​SO4​→BaSO4​+H2​O2​

2BaO+O2​→2BaO2​

4KClO3​→4KClO2​+2O2​

SO2​+2H2​S→2H2​O+3S

Oxidation number of each element on both sides is same.

$B a O_{2} + H_{2} S O_{4} \to B a S O_{4} + H_{2} O_{2}$

$2 B a O + O_{2} \to 2 B a O_{2}$

$4 K Cl O_{3} \to 4 K Cl O_{2} + 2 O_{2}$

$S O_{2} + 2 H_{2} S \to 2 H_{2} O + 3 S$
