Answer 1

I have learned lots of things from this experiment such as the transferring of the solid-sulfur by heating.The solid-sulfur could be heated easily with solid copper and they all changed from reactants into products.During the experiment,we observed the changes of mass,and its appearances.This experiment was of great importance because we could figure our chemical problems and acquired knowledge from it.The experiment’s objective was to validate the conservation law of sulfur and copper.As a result,the significance of the effective copper and sulfur failed with a high temperature; the heat increased energy and quicken the movement of the substance in the solids,and it also increased the pace with the high heat and broke the chemical bond between molecules.The reactants consequently lost their weights.
