  1. 22/24 Marks Practice Chemistry IA on Ethanoic acid in vinegar

    This is an IA I did for HL Chem in DP1, we were pretty much given the topic and I don't think it would be enough for a final IA, but my teacher said it was probably the best she read. I can't remember where I lost the two marks but the main issue with the assignment was that I didn't really have a literature value to compare to, or a scatter graph (which my school requires).

  25. Conservation of Mass in Copper Reactions

    This lab investigates the strengths and weaknesses of experimental procedure. By holding the law of conservation of mass to be true, the experimental results show exactly how much error the procedure caused. In the IA rubric of analysis and evaluation, the report scored 5 and 6 respectively, for a total of 11/12.
