The aim of this experiment is to determine the order of the reactivity series by investigating the thermal breakdown of metal carbonates. Hypothesis When a metal is thermally decomposed the bond between the metal and its carbonate (carbon and oxygen) is removed and the carbonate is released as cerbon dioxide. The reactivity series determines how fast this reaction occurs. The reactivity series is the order metals in the periodic table. The most reactive metals are …showed first 75 words of 3028 total…

…showed last 75 words of 3028 total…this is that the graph was too squashed together, meaning it was difficult to plot the results and draw a line of best fit without getting the points mixed up. If I could do this investigation again I would: ? Do more repetitions ? Test each carbonate myself ? Use the same amount molecules in each carbonate, instead of the same mass carbonate. ? Use a bigger trough ? Have larger time intervals for measuring the amount of Carbon Dioxide.
