Explanation:

A negation of a statement is its opposite. The statement "I am in chemistry class" is negated when it says "I am not in chemistry class" or an equivalent like "It is not the case that I am in chemistry class". Being in a history class or not being in a physics class are not negations of being in a chemistry class.

Answer:

I am not in chemistry class.	Yes
I am not in physics class.	No
It is not the case that I am in chemistry class.	Yes
