Producing Carbon Dioxide from a Metal Carbonate :: Science Thermal Decomposition Essays

Producing Carbon Dioxide from a admixture CarbonateMetal Carbonate Metal Oxide + Carbon DioxideThermal putrefaction is when a substance scarpers polish up into simplersubstances when heated, often with the help of a catalyst. Itsdifferent from a reaction because in that respects only champion substance to startwith. I came across this information in the EDEXCEL modular Sciencerevision guidebook 1. Thermal decomposition is the breakdown of asubstance using thermal energy, this is not a reaction.Preliminary proveLimewater and copper carbonate were utilise to see if a metal carbonatebeaks down to produce carbon dioxide.This is what the experiment looked likeThe equation for thisCaCo3(s) CuO(s) + carbon dioxide (g)This experiment was to see if carbon dioxide was produced from a metalcarbonate. In this character reference copper carbonate was used. Two test pipings were think together by a rubber tube, which had a glass pipe coming step up ofthe cork that prevented any of the carbon dioxide or any other ordnancefrom escaping. As you raft see from the diagram in one tube there waslimewater that was to test for the carbon dioxide, and in the otherwas copper carbonate. If there were carbon dioxide present, thelimewater would turn cloudy (white in colour). When I was observingwhat happened I could see that there was carbon dioxide presentbecause the limewater turned cloudy.Secondary auditionThis experiment was to compare the rates of decomposition of severalmetal carbonates. some(prenominal) metal carbonates were placed in a test tubeand linked to a syringe that measured the amount of carbon dioxide gaswhen the metal carbonates were heated.This experiment is to see how fast metal carbonates will break down toproduce carbon dioxide.The reason they break codt break down at the same time is because more than(prenominal) reactive ones dont want to break up. So the longer it holds ontoits carbonate the more reactive the metal is.In this experiment ther e are a few factors that can affect the resultsof the experiment. These factors can make the results of theexperiment be incorrect. The factors that can affect the experimentare1 Water2 Amounts of powder3 Distance the flame is away from the metal carbonateWater can affect the results because it can get into the powder, whichcan despatch up a reaction.If different amounts of the substance are used, then the results canbe affected because the more amount of powder there is, the morecarbon dioxide will be produced.PlanIn this experiment I plan to use 1/500 of a mole. This is because ifanything greater is used then the amount is too great and the results
