mostly react with 0.200 to 0.300 grams of zinc, 2 grams of iodine will react mostly with 0.400 to 0.600 grams of zinc, and 3 grams of iodine will react mostly with 0.600 to 0.900 grams of zinc. The reaction doesn’t occur if the mass of iodine is between 1 to 2 grams or 2 to 3 grams while zinc tends to react regardless of the quantity at the time. Iodine is the independent variable of the reaction in that the reaction doesn’t occur if the iodine is not at a certain quantity while the zinc is the dependent variable due to relying on iodine to react. The slope of the graph has a very slight angle to it in a straight line. The mass ration of reacted zinc to reacted iodine tend to stay in ratios between 3.700 to 4.000 while the mass of zinc weighted out tend to stay around 1.000g, 2.000g, and 3.000g. The plotted variables tended to stay in 3 columns of data with the mass of zinc to iodine ratio being roughly the same throughout but the zinc weighted out was divided into 3 columns of 1.000g, 2.000g, and 3.000g with slight deviations in the points. Graph 3 shows the relationship between the total mass of reacted zinc and iodine and mass of isolated zinc iodide. The slope of the line goes from 0.500g to 4.500g with the reactions being concentrated in the areas of 1.250g, 2.500g, and 4.000g. The graph shows that the mass is conserved when comparing the mass of the reactants with the product. The zinc and iodine combined have the same mass as its product zinc iodide at 1.000g, 2.000g, and 3.000g. “The properties of a chemical compound are the averages of the elements that make up the compound” is a false statement based on the experiment.
