Question

when ethane is burnt in excess of oxygen the oxidation no of carbon changes by

Answer 1

The oxidation number of carbon when ethane is burnt in excess of oxygen changes by +7

Explanation :

The complete balance reaction when ethane burns in oxygen

C₂H₆ +3.5 O₂------>2CO₂ +3H₂O

oxidation number of carbon in C₂H₆(ethane) = -3

oxidation number of carbon in CO₂ = +4

Hence change in oxidation number = +4 - (-3)

= +7

Hence the oxidation number of carbon when ethane is burnt in excess of oxygen changes by +7

I hope it helps.
