    Ahmed Pasha wrote:Marwa sorry to tell you this but your book is stupid. That is the worst explanation ever. The reason why it is exothermic is because it energy is released when an electron is taken in by a substance, just liek when 2 elements combine to form a compound it is an exo reaction.

    Do you want me to show you how she made us see it?

    Thank you I am aware of that. Well tbh I am surrounded by crazy people in my chem class. We were talking about the surface tension of water, then we talked about how the water strider insect could walk on water, then this kid in my class started speaking about how Jesus (AS) walked on water...and she was answering him...
