Percent Composition Report Hypothesis: By using seperation techniques properly, the 3 substance such as; water, sand, and salt can be seperated and the percent composition of each substance. Which will then be calculated theoritically and after comparison with the actual result, the accuracy of the …
Abstract LDPE and HDPE were processed by extrusion, injection molding, and sheet extrusion. Their mechanical properties such as tensile strength and percent elongation were measured by tensile test and analyzed statistically (Table 2). During the extrusion process, both polymers underwent die swelling. The water cooled …
My aim in this experiment is to see how well an enzyme (phosphatase in this case) reacts under a controlled temperature but a varying pH. Enzymes are known to be effected by pH and temperature. Both of these change how quickly the enzyme can process …

The Development of the Periodic Table Although Dimmit Mendel is often considered the ‘father’ of the periodic table, the work of many scientists contributed to its present form. Between 1817-1829, Johann Doberman began to group elements with similar properties in to groups of three or …
Introduction Stoichiometry is a branch of chemistry that deals with the quantitative relationships that exist among the reactants and products in chemical reactions To predict the amount of product produced in a precipitation reaction using stoichiometry, accurately measure the reactants and products of the reaction, …
Although the aluminum can and the wood chip were ere close together, there was still a large amount of heat loss to the surroundings. This resulted in a lower temperature reading, which in turn reduced our AT value. Thus reducing our overall enthalpy of combustion …
Powder metallurgy is the process of blending fine powdered materials, pressing them into a desired shape or form (compacting), and then heating the compressed material in a controlled atmosphere to bond the material (sintering). The powder metallurgy process generally consists of four basic steps: (1) …
Thomas Graham studied the behavior of the diffusion of gases of unequal densities when placed in contact with each other, using air as his control. He wanted to numerically prove how the diffusion of the gas volumes was inversely proportional to the value of the …
