Types Of Chemical ReactionsAim: To investigate, discuss and identify several different types of chemical reactions through a series of tests and observations.Decomposition of a carbonate by heatingApparatus:SpatulaBunsenTest tube (x2)Copper (II) carbonateStopper and delivery tubeLimewaterProcedure:1. Place a spatular of Copper (II) carbonate (CuCO2) in a test tube.2. Fit with stopper and delivery tube leading into another test tube, filled with limewater.3. Heat the test tube containing the Copper (II) carbonate and observe any changes that take place to it or the limewater.Results/observations: As the light blue Copper (II) carbonate heated, It turned black and created a gas which bubbled through the limewater leaving a milky white precipitate.Discussion: When the Copper (II) carbonate heated, enough energy was present to start a reaction in which it reacted with the surrounding oxygen in which the Copper (II) carbonate decomposed:2CuCO2 + O2 2CO2 + 2CuOCopper (II) carbonate + Oxygen Carbon dioxide + Copper oxideThe Carbon dioxide then travelled through the delivery tube and through the limewater:CO2 + Ca(OH) 2 CaCO3 + H2OCarbon dioxide + Limewater (Calcium hydroxide) Calcium carbonate + WaterThis reaction leaves us with the calcium carbonate precipitate and indication that Carbon dioxide was the gas that was released through the first reaction. From this reaction it is possible to determine that a reaction between a carbonate and oxygen (burning) results in carbon dioxide and a metal oxide.Metal(X) Carbonate + Oxygen (and Heat) Carbon Dioxide + Metal(X) OxideDecomposition of a carbonate with an acidApparatus:SpatularCalcium carbonate2mol L-1 Hydrochloric acidTest tube (x2)LimewaterProcedure:1. Place a spatular of calcium carbonate into a test tube and add 2-3 cm of hydrochloric acid.2. Fit the first test tube with a stopper and delivery tube, leading into another filled with limewater.3. Observe reactions in both test tubesResults/observations:When the hydrochloric acid was added to the calcium carbonate, bubbles formed on the chips and rose to the top of the hydrochloric acid. This gas bubbles through the limewater which formed a milky white precipitate.Discussion:The first reaction which took place between the acid and calcium carbonate, the following reaction took place:CaCO3+2HCL H2O + CO2 + CaCl2Calcium carbonate + Hydrochloric acid Water + Carbon dioxide + Calcium chlorideThis leaves calcium chloride dissolved in water in the first test tube, and as before, the carbon dioxide travelled through the delivery tube and through the limewater where the following reaction took place:CO2 + Ca(OH) 2 CaCO3 + H2OCarbon dioxide + Limewater (Calcium hydroxide) Calcium carbonate + WaterWhich in this case confirms the presence of carbon dioxide.From this it is possible to conclude that when a solid carbonate is decomposed in an acid, carbon dioxide and a metal salt dissolved in water are formed:Metal(X) carbonate + Acid Water + Metal(X) salt + Carbon...
