    Hi I am really desperate In need off help with my gcse controlled assessment for chemistry its worth 25% of gcse.I have to do a part C which is the conclusion of the experiement. The experiment was the decomposition of copper carbonate which we did 5 percentages. We measured out 5grams of each percentage 10% to 30% we tried each percentage 3 times and did a table and calulated the averages of each percentage. My teacher has given me a the assessment of the part C conclusions with some help but I'm really confused about the quality of evidence section I need help on these 2 section please!
    and the conclusions based on evidence section. I have attached pictures of teachers help sheet (which is the actual exam paper) *note these pictures are not the answers just help
