purpose was to recover the original amount of copper after series of chemical reactions. Then returning the copper back to its original form. The copper wire originally weighted 1.0099 g‚ but after the copper was transformed into Cu(OH)2 to CuO to CuSO4 and finally into Cu‚ the mass of the recovered copper was 1.1023g; the percent yield was 109%. Since the percent yield is more than 100%‚ an error must have occurred somewhere in the lab. A possible error could have occurred due to removing the evaporating

Extraction of Aluminium Aluminium ore is called bauxite. Bauxite contains aluminium oxide‚ water‚ iron oxide and other impurities. The purified dry ore‚ called alumina‚ is aluminium oxide (Al2O3). The alumina must be molten for electrolysis to work‚ since the ions are not free to move in the solid state. Unfortunately‚ alumina has a high melting point (2040 °C) and it is not practical to do electrolysis at such a high temperature. In the middle of the nineteenth century it was found that alumina

The University of Toledo Soil Mechanics Laboratory 1 Grain Size Distribution – Sieve Analysis Introduction The grain size distribution is a representation of the approximate distribution of soil grain sizes for a soil. The sieve analysis‚ also called mechanical method‚ measures the dry mass of soil retained on each sieve in a stack of sieves‚ where the sieve opening sizes vary from the largest to smallest going from the top to the bottom of the stack. All the soil particles retained on a particular
