What is the oxidation number for lead? +4 What is the oxidation number of V in VO2+? What is the oxidation number of V? The vanadium is now said to be in an oxidation state of +2. Removal of another electron gives the V3+ ion: The vanadium now has an oxidation state of +3. What […]

Why water has high boiling point and freezing point? So despite its small molecular weight, water has an incredibly big boiling point. This is because water requires more energy to break its hydrogen bonds before it can then begin to boil. The same concept is applied to freezing point as well, as seen in the […]

How do you solve chain rule problems? Solution: To use the chain rule for this problem, we need to use the fact that the derivative of ln(z) is 1/z. Then, by the chain rule, the derivative of g is g′(x)=ddxln(x2+1)=1×2+1(2x)=2xx2+1. Where do we apply chain rule? The chain rule can be applied to composites of […]
