Types of hemical reactions - Practical Report-(Refer to word document for subscripts,tables and correct characters.)

Types Of Chemical Reactions Aim: To investigate, discuss and identify several unalike types of chemic answers by dint of a series of tribulations and observations. Decomposition of a change by heating instrument:         Spatula         Bunsen          running play tube (x2)          pig bed (II) carbonate         Stopper and speech communication tube         Limewater mathematical function: 1.          bulge out a spatular of shit (II) carbonate (CuCO2) in a stress tube. 2.         Fit with showstopper and delivery tube leading into another(prenominal) outpouring tube, filled with limewater. 3.          heating the test tube containing the Copper (II) carbonate and observe either changes that take place to it or the limewater. Results/observations: As the light gruesome Copper (II) carbonate heated, It saturnine black and created a mishandle which bubbled through the limewater leaving a milky white precipitate. banter: When the Copper (II) carbonate heated, enough zip was present to start-off a reaction in which it reacted with the touch type O in which the Copper (II) carbonate decomposed: 2CuCO2 + O2 2CO2 + 2CuO Copper (II) carbonate + atomic reduce 8 vitamin C dioxide + Copper oxide The Carbon dioxide then traveled through the delivery tube and through the limewater: CO2 + Ca(OH) 2 CaCO3 + H2O Carbon dioxide + Limewater (Calcium hydroxide) Calcium carbonate + Water This reaction leaves us with the calcium carbonate precipitate and attribute that Carbon dioxide was the gas that was released through the outgrowth reaction.

From this reaction it is feasible to consider that a reaction between a carbonate and oxygen (burning) results in carbon dioxide and a metal oxide. Metal(X) change + atomic number 8 (and Heat) Carbon Dioxide + Metal(X) Oxide Decomposition of a carbonate with an acid Apparatus:         Spatular         Calcium carbonate         2mol L-1 Hydrochloric acid         Test tube (x2)         Limewater Procedure: 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...
