To find which equation is correct, we can use ideas about the mole and the volume one mole of gas, 1 mole of any substance contains the same number of particles as 12g of carbon-12. calculating the volume of gas This student written piece of work is one of many that can be found in our AS and A Level Organic Chemistry section. In this case, Benedict’s solution which is aqueous solution of copper (II) sulphate, sodium carbonate and sodium citrate, used as a test of the presence of reducing sugar. After the test tube containing the residue has cooled, weigh it and record the mass of the test tube + residue on your lab report. The five general types of chemical reactions are synthesis (also known as direct combination), decomposition, single replacement (also known as single displacement), double replacement (also known as double displacement), and combustion. Test tube holder 0.1M KI ------- Thermal Decomposition of Metal Carbonates [Online] Available at: [Accessed 03 December 2010] 6. The extraction and isolation of metals from ores involve the following major steps: 0000005225 00000 n 2CuCO3 (s) --> Cu2O (s) + 2 CO2 (g) + 1/2 O2 (g) b. CuCO3 (s)--> CuO (s) + CO2 (g) Aim: In this experiment we will be required to identify the correct balanced stoichiometric chemical equation for the decomposition of the copper carbonate from the volume of carbon dioxide produced. %PDF-1.3 %���� the temperature and pressure at the core and thus, ultimately, on the mass of the star. I have also discovered that isomers of an alcohol do have an effect on the enthalpy change. Health and Safety Executive, General hazards of carbon dioxide [Online] Available at: [Accessed 07 December 2010] 3.

Riddle J.P, 1999. , 4/13/12-4/14/12 The residue in this reaction is copper (II) oxide. Material safety Data sheet, 2007. In this way, the carbonates of sodium and potassium are stable at the highest temperatures of a Bunsen burner flame whereas the carbonates of silver and copper are easily decomposed. I will firstly need to consider methods of trying to separate the Figure 2 clearly shows that the there is the simultaneous loss of water, carbon dioxide and some oxygen. produced. The products obtained at 400‡C were subjected to different doses of gamma … Investigating the Thermal Decomposition Of Metal Carbonates Equation 1: 2CuCO3 (s) Cu2O (s) + 2CO2 (g) + O2 (g) �[�EA��mQ[�գ��b�����_��v����EW��T5� �p� y�Vu�I '�cy4��q�QK�����>��>�':�"���_��c`��� ˲޺��� �s�������03�4� t�#��䑁:���X�|��ZܒbR%�x ��;1ʐJ����~�;��V�Ш�V����%ҐH��'���k`�.d�56��/u�5�=� �5��a�ē7�}u��R�$��"k(^�侤fgW�y�P D����o2�'RA5DI:L%R~��۪���.O�i��ܻAk�I�@�֨ͺ|T�q�&Y�jU���+�����l�y-]�K�>X�&o^Ysu���x�.\mR����D^�9�(Ѡ�7����֪#�7��!e��U���3��{]����b�����G��pk��(�y��O`b��F�q�gZ�h� 0 �u� endstream endobj 36 0 obj << /Type /FontDescriptor /Ascent 891 /CapHeight 656 /Descent -216 /Flags 34 /FontBBox [ -568 -307 2000 1007 ] /FontName /OCEABA+TimesNewRoman /ItalicAngle 0 /StemV 94 /XHeight 0 /FontFile2 59 0 R >> endobj 37 0 obj << /Type /Font /Subtype /Type0 /BaseFont /OCDPPO+SymbolMT /Encoding /Identity-H /DescendantFonts [ 62 0 R ] /ToUnicode 38 0 R >> endobj 38 0 obj << /Filter /FlateDecode /Length 217 >> stream 0000009249 00000 n t u � � � � � � � 0000082637 00000 n Apparatus: * Copper Carbonate - CuCO3 (s) - 0.20g * 1 Test tube ( fitted with rubber stopper with glass tubing) * Delivery tube * Clamp and stand * Big bucket * Water * Bunsen burner * Matches * Balance * Spatula * 50ml - Measuring cylinder * Extra - Safety goggles - Gloves * Access to a fume cupboard RISK ASSESSMENT: Compounds used or produced Quantity: Produced/ Used Hazard Safety precautions Storage Disposal Copper Carbonate [CuCO3 (s)] 0.2 g Low reactivity Toxic to plants and fungi.
