    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. Sublimation was used to purify

    Determining Capacity Requirements Capacity planning decisions involve both long-term and short-term considerations. Long-term considerations relate to overall level of capacity‚ such as facility size; short-term considerations relate to probable variations in capacity requirements created by such things as seasonal‚ random‚ and irregular fluctuations in demand. Because the time intervals covered by each of these categories can vary significantly from industry to industry‚ it would be misleading to

    • 15 Pages

    Capacity Planning The overall objective of strategic capacity planning is to reach an optimal level where production capabilities meet demand. Capacity needs include equipment‚ space‚ and employee skills. If production capabilities are not meeting demand‚ high costs‚ strains on resources‚ and customer loss may result. It is important to note that capacity planning has many long term concerns given the long term commitment of resources. Managers should recognize the broader effects capacity

    Analysis of an Unknown Mixture Performed: 2/13/14 Submitted: 3/3/14 Abstract: The purpose of this experiment was to separate and identify the two unknown compounds. The sample used was 105 and it contain 2-propanol and 2-heptanone. IR spectrums were taken of the contents of the second and sixth test tubes and showed the presence of an OH functional group and a small amount of ketone in test tube two and a large presence of ketone in test tube six. The average boiling points of the test tubes

    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 or compound‚ is by studying the actually

    droplets with respect to heat capacity and droplet size Abstract Define Using Molecular dynamic simulation a cluster of particles was modelled and their behaviour analysed with respect to temperature change. As proof of a specific state i.e. solid‚ the Mean squared displacement was calculated and illustrated with respect to time. This occurred for varying temperatures. From the internal energy of the system per time step‚ the heat capacity was determined. Heat capacity was then plotted against

    Methods for Synchronizing Cells at Specific Stages of the Cell Cycle The protocols presented here describe procedures used to synchronize cells in various stages of the cell cycle (Fig. 8.3.1). Synchronization is particularly useful for investigating a particular cell cycle–regulated event or preparing cells for extraction of transient factors whose expression is dependent on cell cycle stage. Exponentially growing cultures are generally asynchronous; i.e.‚ each cell progresses through the cell

    separation of the components of a mixture. A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically combined. All of these techniques involve changes in the physical state of a chemical compound rather than chemical changes. Sea sand‚ table salt‚ and two other unknown substances will be separated using the separation techniques in order to demonstrate the properties of mixtures and their ability to be separated
