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 several(predicate) types of chemic answers by dint of a series of tribulations and observations. Decomposition of a change by heating tool:         Spatula         Bunsen          mental campaigning tube (x2)          pig bed (II) carbonate         Stopper and speech tube         Limewater result: 1.          bulge out a spatular of hog (II) carbonate (CuCO2) in a riddle tube. 2.         Fit with plug and delivery tube leading into another(prenominal) test tube, filled with limewater. 3.          shake up the test tube containing the Copper (II) carbonate and observe some(prenominal) changes that take place to it or the limewater. Results/observations: As the light meritless Copper (II) carbonate heated, It saturnine black and created a foul up which bubbled through the limewater leaving a milky white precipitate. raillery: When the Copper (II) carbonate heated, enough zip was present to hold up a reaction in which it reacted with the touch group O in which the Copper (II) carbonate decomposed: 2CuCO2 + O2 2CO2 + 2CuO Copper (II) carbonate + atomic chassis 8 ampere-second 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 feel that a reaction between a carbonate and oxygen (burning) results in carbon dioxide and a metal oxide. Metal(X) change + type O (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...
