Synthesis of Copper Sulfide Discussion , chemistry homework help

In your discussion you should make a conclusion and then explain how your group’s experimental results and observations support your conclusion. The points below should help you identify the information you have available from this experiment to support your conclusion.
a. A claim. Based upon the purpose of your experiment, what claim can you make using your experimental evidence? What is the name of the copper ore produced?
b. A table of your results. Include mole ratio and physical properties of the product and the possible products.
c. Discussion of your results.
i. Explain how your experiment results support your claims.
i. Explain discrepancies between expected and experimental results
ii. Compare your individual results with the group results.
iii. Are the physical properties of your unknown consistent with your conclusion?
iv. Briefly explain atom economy and the significance of the atom economy for this reaction.
d. Uncertainty and Error in measurements.
i. Identify at least three (3) possible sources of uncertainty and error in this experiment.
ii. Use evidence from your laboratory notebook to evaluate the validity of these sources of uncertainty.
iii. Discuss the error sources you have evaluated.
e. Supporting references that demonstrate the validity of your method.
