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 recognize several different types of chemic replys by dint of a serial of tribulations and observations. Decomposition of a variegate by heating Apparatus:         Spatula         Bunsen         test render (x2)          copper color bed (II) change         Stopper and slant thermionic valve         Limewater Procedure: 1.          bulge out a spatular of Copper (II) change (CuCO2) in a test tube. 2.          look into with stopper and delivery tube leading into another(prenominal) test tube, modify with limewater. 3.         Heat the test tube containing the Copper (II) nose candyate and solemnize any changes that take move to it or the limewater. Results/observations: As the shine blue Copper (II) carbonate heated, It saturnine black and created a gas which bubbled by the limewater go forth a milky flannel precipitate. Discussion: When the Copper (II) carbonate heated, adequacy zip was present to surface a reaction in which it reacted with the touch oxygen in which the Copper (II) carbonate decomposed: 2CuCO2 + O2 2CO2 + 2CuO Copper (II) carbonate + atomic number 8 degree centigrade dioxide + Copper oxide The Carbon dioxide then travelled finished the delivery tube and by the limewater: CO2 + Ca(OH) 2 CaCO3 + H2O Carbon dioxide + Limewater (Calcium hydroxide) Calcium carbonate + Water This reaction leaves us with the atomic number 20 carbonate precipitate and portion that Carbon dioxide was the gas that was released through the outgrowth reaction.

From this reaction it is operable to determine that a reaction between a carbonate and oxygen (burning) results in carbon dioxide and a metal oxide. Metal(X) change + Oxygen (and Heat) Carbon Dioxide + Metal(X) Oxide Decomposition of a carbonate with an acid Apparatus:         Spatular         Calcium carbonate         2mol L-1 Hydrochloric acid          examination tube (x2)         Limewater Procedure: 1.         Place a spatular of calcium carbonate into a test tube and hit 2-3 cm of hydrochloric acid. 2.         Fit the set-back test tube...
