Assuming you mean can entropy be reduced; the answer is yes. Only in an open system such as our planet. The universe is a closed systems. The entropy of the universe cannot be reduced.

Chemical changes can reduced entropy in an open system. When gas turns into a liquid or when a liquid turns into a solid; entropy is reduced.

Q: Is it possible for entropy to be negative and For entropy change to be negative and For entropy production to be negative?

entropy is decreasing, so negative

Negative (A+) AG : )

Please be aware that the change will be neither positive or negative. You see when "water" freezes the entropy will not change due the tempertaure of the area around it meaning the entropy will stay neutral. You are very welcome young man

Negative entropy is a process or chemical reaction proceeds spontaneously in the forward direction.Positive entropy is a process proceeds spontaneously in reverse.

Positive

increase

Because the entropy is negative making it spontaneous.
