well heluim and catalyst,Even though i didn't get there and i told you that i finished every thing beside the macro moleculars but i got this from before, amide is the linking group of atoms!, there are many types of amide +many uses, for example acrylamide:used for soil stabelisation.
for the redox reaction:That is not reqierd , stop being clever , ihave been solving past papers form 2000 to 2009 may and october , the only thing that is requierd is:
-define redox in terms of electron transfer
-identify redox reactions by changes in
oxidation state and by the colour
changes involved when using acidified
potassium manganate(VII), and
potassium iodide. (Recall of equations
involving KMnO4 is not required.)
So any other quetions WITH IN THE SYLLABUS OF THE IGCSE !!!!!! I repeat Stop being clever
Catalyst: In your face!?
Any quetions!
