When 109.27 g of pure copper reacts with 488.28g of iodine, 546.35g of a compound containing only copper and iodine result. 51.20g of iodine remain when the reaction is complete.

a. Do these results support the Law of Conservation of Mass? Explain

b. Another student heat 5.10g of copper with 7.00g of iodine.The product is a white compound with mass of 10.50g with 1.60g of copper left over. Is the compound made in this experiment, the same or different than the first one? If different prove that these two experiments together support the Law of multiple proportions.
