measured‚ and .9 to 1.2 grams of aluminum can pieces are added to the beaker. The mass of the beaker and aluminum pieces is recorded. These two masses are then used to determine the initial mass of aluminum being reacted in this experiment. 50 mL of 1.4 M KOH is then added to the beaker and placed upon a hot plate under a fume hood to fumigate any escaping gases during the reaction‚ which should take no longer than 30 minutes. The heat from the hot plate speeds the reaction‚ and the reaction mixture must

Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements
