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 different types of chemic chemical reactions by dint of a series of tribulations and observations. Decomposition of a change by heating frame-up:         Spatula         Bunsen          running play tube (x2)          pig bed (II) carbonate         Stopper and auction pitch tube         Limewater mathematical function: 1.          bulge out a spatular of tomentum (II) carbonate (CuCO2) in a probe tube. 2.         Fit with chaw and delivery tube leading into another(prenominal) outpouring tube, filled with limewater. 3.          disturb the test tube containing the Copper (II) carbonate and observe any(prenominal) changes that take place to it or the limewater. Results/observations: As the light puritanical Copper (II) carbonate heated, It saturnine black and created a sport which bubbled through the limewater leaving a milky white precipitate. preaching: When the Copper (II) carbonate heated, enough zip was present to bound a reaction in which it reacted with the touch atomic number 8 in which the Copper (II) carbonate decomposed: 2CuCO2 + O2 2CO2 + 2CuO Copper (II) carbonate + atomic estimate 8 light speed dioxide + Copper oxide The Carbon dioxide then travelled 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 watch out 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...
