Title: Separation of a Mixture of Solids Purpose: Learn and demonstrate how to separate different ingredients from a mixture of solids using different methods based on the properties of each ingredient. Procedure: I weighed mixture and tools‚ and proceeded to begin separating each ingredient. I used a magnet to separate the iron from the mixture. Then I heated the mixture in water to get the non-soluble sand out. Then I filtered out the benzoic acid after cooling it into a crystal form

The purpose of this experiment was to test the tonicity of potato cells. The potato cells were placed in different test tubes with water and were left there for 15 minutes. The percent change in mass is then used to determine if the cells lost or gained water‚ therefore determining the tonicity of the cell. Although it was a brief short time‚ the final results showed that the more water the potatoes were placed in‚ the more hypotonic the potato becomes. Tonicity is stated to be the state of a solution

The separation of powers and federalism are the two major foundational elements within the US Constitution. Behind the rationales of the separation of powers and federalism in the United States is ultimately to ensure liberty‚ stability and harmony amongst the people within the United States‚ by preventing the consolidation and concentration of power within government‚ contributing to what we see as American exceptionalism today.

Chromatography Experiment of the Drosophila Eye Pigmentation Pathway Introduction: How can the use of chromatography help explain single gene mutations of the drosophila melanogaster bio-synthetic pigment pathway? This experiment was meant to help connect the mode of inheritance with different eye color mutations and pinpoint where they occur in the pigment pathway. The drosophila eye color is a result of two bio-synthetic eye color pathways‚ this is expressed as a trait or phenotype‚ a multigene

EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered
