In this experiment‚ we used acquired observational data to develop an activity series describing the relative reactivity of the metals being tested. The elements within a periodic table often show different trends in physical and chemical properties depending on the period or group they are apart of. In a periodic table‚ elements are arranged by increasing atomic number in horizontal rows called periods. The atomic numbers represent the number of protons in each element. The periodic table is also

CHEMICAL KINETICS RESULTS AND DISCUSSION The balanced equation of the reaction between sodium thiosulfate and Hydrochloric acid is: S2O32- (aq) + 2 H+ (aq) SO2 (g) + S (s) +H2O (l) Using beakers with the same diameter was very important in conducting the experiment. If different sizes were used‚ the visibility of the “x” on the paper beneath the beaker could disappear from view too early or too late than the hypothetical time depending on the depth of the solution. It was also significant
