Abstract: For the first part of this lab we refluxed different Carboxylic acids and alcohols in the presence of a acid catalyst in order to form Esters by Fischer Esterification. These Esters had different pleasant smells that we then evaluated. In the second part of the experiment‚ we broke the ester bonds of a triglyceride in order to form glycerol and carboxylate salts. This process is known as Saponification because it produces amphiphilic molecules that allow soap to remove dirt from the surface

McLean 1 Creating Acetylene Gas Introduction The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel

Darwin’s Finches Lab In this inquiry lab‚ we explored natural selection using a laboratory. We wanted to see what was the effect of the type of food available on the frequency of different types of bird beaks. Our hypothesis was that If the type of the food available changes‚ then the frequency of beak types will change‚ because birds with beaks more suited to the available food will be more successful over time. Variables: Independent Variable: type of food available

layer of geological area the lithosphere. Soil is actually nothing more but the remnants of the Earth’s Mountains and the life that has lived on this planet through the natural process of erosion and time on Earth. A good soil is said to be composed of 5 % organic material 25% Air 25% water‚ 45% of inorganic material which could be either sand‚ silt‚ or clay. Being almost a majority these 3 categories have a lot to do with soil’s relationship with its second most important component‚ water. It has
