Saline Salt Company Analysis The Saline Salt Company production process was simple. Their process involved extracting salt from six tanks of 900‚000 cubic feet of seawater which could only be held on a large plot of land. As land becomes more valuable and rarer‚ expansion of the existing method becomes very difficult. Saline Salt Company could not compete with other companies that were producing larger amounts of salt in shorter amounts of time. Saline Salt Company did not expand as the needs

Heterotrophs are any organism that consumes organic carbon and energy that is fixed by primary producers. This unit discussed an extremely important pyramid‚ somewhat like a food chain that categorizes heterotrophs. 1st level of the pyramid are herbivores‚ 2nd level are carnivores. Eukaryotes are single celled or multi-celled‚ recapped in this unit‚ the primary consumers are the herbivores‚ the secondary consumers are the herbivore consumers‚ and the tertiary consumers are the top predators.

Separation Techniques If one component of the mixture has magnetic properties‚ you can use a magnet to separate the mixture. Cobalt‚ iron and nickel all have magnetic properties. Note that not all metals are magnetic and magnetism is not a method to separate metals from non-metals. Gold‚ silver and mercury are examples of non-metal substances. Magnetism is however a way to separate magnetic substances from non-magnetic substances is. Magnetism as a separation method is done by taking any magnetic

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

If only they knew what was in the mystery mixture. After a long time of experimenting‚ the 8th grade scientist came to a decision on how they are going to figure what is in the mystery mixture. Once they started‚ they all looked at its physical properties. Then the scientists thought about the chemical reactions‚ and how that will help the claim the scientists had. More than half of the scientists thought it was baking soda and citric acid. When combining baking soda and citric acid together‚ the

The Purity and Purification of Solids Melting Point Lab Introduction: The point of this lab was to determine the eutectic point for the naphthalene biphenyl mixture‚ as well as determining the melting point of an unknown substance by comparing it with two known samples. Melting point is a temperature in which a substance changes from solid state to liquid state. Melting points are used to determine whether the given substance is pure or not. Substances that melt sharply‚ less than 1-2°C indicates

AGUILAR AGUILAR INTEGRATED SCHOOL Aguilar DEMO LESSON PLAN I. Objectives: 1. Show how mixture is formed. 2. Describe ways of Separating Mixtures. II. Subject Matter: Mixture Reference: Science for Daily Use 4 A. Science Concept A mixture is a combination of two or more different substances where their individual characteristics are maintained. Ways of separating mixtures are: evaporation‚ filtration‚ sieving‚ sifting‚ straining‚ winnowing and through the use of magnets

Abstract By separating chemicals out of a mixture and purifying them through sublimation and recrystiliation‚ changes in the substances physical properties can be shown. A salicylic acid-naphthalene mixture was mixed together with diethyl ether and saturated sodium bicarbonate. Two layers separated and were extracted after acidifying with HCl. This precipitated the crude salicylic acid. The left over mixture was combined with water and the two layers separated where crude naphthalene was recovered

Sawdust has many known uses and has been proven to be a good fertilizer. The researchers wanted to find out if sawdust can serve as an alternative medium to soil and thus the study was begun. For this experiment the researchers tested the following mixtures: pure soil (A)‚ pure sawdust (B)‚ 90% soil (C)‚ 90% sawdust (D)‚ 80% soil (E)‚ 80% sawdust (F)‚ 70% soil (G)‚ and 70% sawdust (H). Each set-up was planted with five seeds. The set-ups were observed for a period of five weeks. Once a week‚ the researchers

September 25‚ 2013 Lab Section: CHE110L*Z Purpose The purpose of this experiment is to use two common laboratory methods to see how mixtures can be separated based on physical properties. Paper chromatography will be used to separate the dye colors from M&M candy to see which colors contain yellow #5. Gravimetric separation will be used to separate salt and sand from a mixture. Procedure The procedure for this lab can be found on pages 16 – 30 in “General Chemistry CHE110L Laboratory Manual Fall 2013”
