Lol I was gonna start B7 then I decided to read the whole question first and then left it :p.

I wasted 15 minutes on structure of ester and that's why I lost most of my time. I made it 6 times and crossed it out. The space was filled so I continued on a blank page. Im not sure whether I made it correct in the end. Can someone make it and show?

Umm...can't tell if you are being sarcastic or noto_O....because iron is extracted in a blast furnace:) and I knew that slag was collected at the bottom, I was just tensed about some other questions and messed up this one too by changing it from calcium silicate to iron at the last moment:cry:..I just asked because I didn't want to look through my chemistry notes and discover what more I did wrong:(
