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

Producing Carbon Dioxide from a Metal changeMetal Carbonate Metal Oxide + Carbon DioxideThermal decomposition is when a amount of money breaks mess into simpler depicted objects when heated, often with the help of a catalyst. Its various from a reaction because in that respects only one substance to startwith. I came across this information in the EDEXCEL Modular cognizancerevision guidebook 1. Thermal decomposition is the break refine of asubstance using thermal energy, this is not a reaction.Preliminary examineLimewater and squealer color ampere-secondate were used to distinguish if a admixture snowatebeaks down to learn carbon dioxide.This is what the audition looked likeThe equation for thisCaCo3(s) CuO(s) + Co2 (g)This try was to see if carbon dioxide was produced from a metalcarbonate. In this case copper carbonate was used. Two test tubes werelinked together by a rubber tube, which had a glass pipe coming out ofthe bobsleigh that prevented any of the carbon dioxide or any other gasfrom escaping. As you git 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 ExperimentThis experiment was to compare the rates of decomposition of severalmetal carbonates. Several 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 dont break down at the same time is becausemore excited ones dont want to break up. So the longer it holds ontoits carbonate the more reactive the metal is.In this experiment there are a few factors that can affect the results of the experiment. These factors can make the results of theexperiment be incorrect. The factors that can affect the experimentare1 peeing2 Amounts of pulverization3 Distance the flame is away from the metal carbonateWater can affect the results because it can get into the powder, whichcan speed 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 proposal to use 1/500 of a mole. This is because ifanything greater is used then the amount is too great and the results
