TO QUESTIONS 1. How does the use of fluted filter paper hasten filtration? Why is it advisable to place a small piece of wire between the funnel and the mouth of the flask during hot filtration? Fluted filter paper is effective in preventing crystal formation in the filter paper. It is also often used in filtering hot saturated solution used during crystallization. One major advantage of a fluted filter is that it increases the speed of filtration. The crisscrossing of the folds help alleviate

Smart System or Structure What is a Smart Structure? A smart structure is a system containing multifunctional parts that can perform sensing‚ control‚ and actuation; it is a primitive analogue of a biological body. Smart materials are used to construct these smart structures which can perform both sensing and actuation functions. If truly smart‚ these intelligent systems can determine their present state‚ decide what is the optimum or more desirable state and carry out an appropriate

What is the relationship of organizational structure‚ control and culture? When would a company decide to change from a functional to a multidivisional structure? Between the structures‚ the controls and the culture is a relationship that works like a chain that is locked to itself. Organizational structure specifies procedures‚ controls‚ and decision-making authority. It is critical to match organizational structure to the company strategy. The structure have the purpose of manage the firm’s daily

Purpose: The purpose of our experiment was to determine the amount of water in copper sulfate pentahydrate expressed as a percent. Hypothesis: I think that bluestone crystals are 20% water‚ because it’s called pentahydrate (penta means five) and 1/5 of 100 (since it’s expressed as a percent) is 20‚ so I think bluestone crystals are 20% water. Procedure: The following list includes the materials and supplies we used in the experiment: 1) Crucible and Lid 2) Tongs 3) Alcohol Burner

made using the 40-pin AT89C52 microcontroller. This propeller display is mechanically scanned and displays the characters in digital format. Made from scrape it can be used anywhere and everywhere and the most amazing fact about the display is its crystal clear display. This display consists of just 23 bright LED’s which are rotated to show the display. For building the project‚ requirement 40 pin microcontroller and LED’s. this display can show the message‚ which will require a whopping 1504 LED’s

free to move past each other but still held together. Lastly there a solids which are molecules formed in a rigid formation which have a very strong attraction with repeating crystals and can only move in vibrations. Glass is none of the above‚ it is rigid like a solid‚ but its molecules are not arranged with repeating crystals which makes it amorphous like a liquid. "If you could preserve a window long enough‚ it might become a rigid puddle on the floor" (Ediger:1999‚Discover Magazine) Glass can

the time we return to the initial temperature‚ nearly all of the original material has formed crystals‚ which can be removed from the solvent by filtration. Now‚ suppose that the original solid contained small amounts of impurities. These would go into solution as well‚ but since the impurities are present only in small amounts‚ they remain soluble when the temperature is lowered again. Thus‚ the crystals‚ which come out of solution‚ are more pure than the original sample. This is the essence of purification

LABORATORY REPORT 4 PREPARATION OF ALUM FROM ALUMINUM METAL Huy Nguyen October 2nd‚ 2012 The objective of the laboratory is to synthesize alum (KAl(SO4)2.xH2O) from aluminum powder and to determine the proportion of water in the alum crystals. Alum is a product from the reaction between potassium hydroxide and sulfuric acid. The reaction include several steps‚ as followed: Aluminum powder reacts with potassium hydroxide to generate Al(OH)4- ions and release hydrogen. 2 Al(s) + 2 KOH(aq)
