Hi,
My name is Mahmoud Ammar, and I live in Lebanon. I প্রণয় CHEMISTRY so much, and I প্রণয় to help people in chemistry and proving to people that chemistry is not hard and it's beautiful, so I created my own PAGE on ফেসবুক to put in it articles, lessons and funny things about chemistry. I named it : I'm in প্রণয় with chemistry.

so plz can u support me and like and share it on ফেসবুক coz i want to help people to প্রণয় chemistry :D
