YO JUST WANTED TO KNOW HOW TO GET FULL MARKS

Guys,why are you even requesting that guy "whoeven" to stop posting his *artworks*?Let him do so.

If you are feeling disturbed or sick by seeing his pics,then just imagine him to be a guy who has badly failed in his human anatomy drawing works and is thus,trying to gain popularity by posting his *artworks* here.That's it.I bet you won't feel that bad after thinking in this way...^_^

(P.S. i know this question is gonna get bombarded with his *artworks*,but it will be him    who will make fun of himself by posting his pic in this post)

whoven, i realize that it is pointless arguing with you and that you don't give a damn about what others tell you... here is a proposition:

I have a friend who is good at tracking ip addresses for almost any situation. If we do get our hands on yours, we could make life a living hell for you, track you down to your home, and then set the police on you. If you don't stop doing this crap, you can be sent to juvenile homes or even prison.
This is my last warning. If after today, i see any post of yours containing pics of you mom the way you draw it, your life will change drastically after the month of April ends.

differentiate between dil hcl and dil hno3 with chemical test?
