Well, it won't kill you right away, but it would certainly harm you.

Remember that, when microwave heats up things, the heat is not even. If you put a soup bowl or big cup of water in the microwave and heat it for 1-2 minutes, then you can tell that certain part of the content is hotter than the other. This is very bad for the chemicals. Imagine that the outer part of the chemicals are already 110F degree, but it is only 80F in the middle. I just do now know what is going to happen to the chemicals.
