LS Separation of Mixtures and Solids Purpose: To become familiar with the separation of mixtures of solids Hypothesis: I will be able to separate the materials using a variety of different methods. First‚ separate the iron fillings using a magnet. Second‚ I will put the rest of the solution into water and separate the insoluble sand from the soluble salt and benzoic acid. Third‚ I will filter out the benzoic acid when crystalized. Lastly‚ I will evaporate the water away leaving crystallized

turesRule of Mixtures Composite stiffness can be predicted using a micro-mechanics approach termed the rule of mixtures. Assumptions 1. 2. 3. 4. 5. 6. Fibers are uniformly distributed throughout the matrix. Perfect bonding between fibers and matrix. Matrix is free of voids. Applied loads are either parallel or normal to the fiber direction. Lamina is initially in a stress-free state (no residual stresses). Fiber and matrix behave as linearly elastic materials. Longitudinal Modulus Equal strain

take spinach leaves and extract the chlorophyll and carotenoid pigments by using acetone as the solvent. The chlorophyll and carotenoid pigments were extracted by using column chromography and alumina was used as the solvent. Solvents of different polarities were used‚ starting with the least polar‚ to extract the certain components from the leaves. They were then analyzed by using thin- layer chromatography. Procedure: The first part of the experiment dealt with breaking down the spinach leaves

Ocean county college | SEPERATION OF A MIXTURE OF SOLIDS | DEPARTMENT OF CHEMISTRY | | John Curran | 2/23/2013 | COURSE INSTRUCTOR DR. NANCY MARASHI. | Background: During this experiment students will take a mixture and separate it into its’ pure substances. A mixture is a combination of two or more substance. These substances cannot be combined chemically but more physically. The pure substances are substances that cannot be separated any more by physical means. The students

Summary of Random Passage Random Passage‚ a book written by Bernice Morgan‚ is a novel that takes the reader back to the rural‚ unpopulated Newfoundland. The setting in which the book takes place is Cape Random which is a desolate cape off the shores of Newfoundland. This is a fictional place and is based on a real location‚ Cape Island‚ where Bernice Morgan’s ancestors lived. The book contains many rich characters all trying to thrive‚ survive‚ and live on this desolate cape. The novel focuses

CO2 on the rate of Photosynthesis in Spinach Leaves Introduction Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. The purpose of this experiment is to see how different concentrations of carbon dioxide affect the rate of photosynthesis in spinach leaves. I hypothesize that the greater

the substance that can be two or more elements that can be changed. Water is a compound. It contains both Hydrogen and oxygen that can stand alone by itself. The mixture is when two different substances that are blended together. The air is a mixture of these elements carbon dioxide‚ nitrogen‚ and other stuff. Most mixtures are known to be naturally. The main difference between the compound and the mixture is how they are combined. In the pure substance‚ the only way to know if it is an element

Experiment 2: Separation of a Mixture of Solids Purpose: This experiment allowed me to learn different separation techniques for various substances based on their specific chemical properties. Procedure: I began this experiment by using a magnet to pick up and collect the iron filings out of the mixture. Then the sand was separated by placing the mixture into a beaker and boiling it in distilled water in order to dissolve the salt and benzoic acid‚ once boiling the liquid was poured out leaving
