  1. A 16.66% decrease
  2. B 16.66% increase
  3. C 50% increase
  4. D 50% decrease
Verified Solution

Answer & Solution

Correct Answer

(B) 16.66% increase

Step-by-step Solution

Detailed explanation

LiCoO2 The oxidation state of lithium is +1 and oxygen will show -2.Let oxidation state of Co is xSo, LiCoO2; 1×1+x+2(-2)=0        …
