Bunsen burners heated two crucibles supported on clay triangles to red heat for no more than five minutes. After allowing the crucibles to cool, they were placed in a desiccator to cool to room temperature. The crucibles were weighed to 0.1 mg once they had reached room temperature. About .5 g of the air dried product was cautiously weighed into each crucible. The crucibles were once again placed on clay triangles and heated gently. After the product began to solidify, the Bunsen burners were adjusted so that maximum heat was provided to the crucibles for about five minutes. The crucibles were set aside to cool, and then placed in a desiccator to fully cool to room temperature. Once room temperature was reached, the crucibles were weighed to 0.1 mg. The mass of water of crystallization in the sample is represented by the loss in mass of the…

The burner was turned on and the flame came out from the top part. The beaker filled with the weighted hydrate inside, was held over the open flame for few minutes. Visible vapor came out from the beaker, when parts of water were evaporated out of the hydrate. The color of the compound has changed from bright blue to white. After letting the beaker cool down, it was placed on the scale (The scale was initially zeroed out with the beaker, before the hydrate was placed inside) and the new result was recorded in a table (0.498g). The procedure of heating the hydrate in a beaker over an open flame was repeated three more times and the weighting procedure was repeated, the new results were recorded in a table (0.478g, 0.474g, 0.460g) Finally, when the last two measuring weight results were equal (0.460g=0.460g), the decision was made that all the liquid was evaporated from the compound. The procedure was repeated second time for more accurate results. The results were recorded in a table (0.615g, 0.584g, 0.572g, 0.566g) and…
To relief the high demand of energy, countries like United States, Venezuela and especially Canada with 232 billion bbl recoverable unconventional reservoirs which contain bitumen, heavy oil and extra heavy oil as remarkable resources of energy. The reducing high quality oil resources and increase of oil price contributed to production from heavy oil reservoirs in recent years.…

Gettingthe accurate density of the said materials and reagents was determined by using the mass andvolume of the substances. Also, in this experiment the rules of significant figures were applied inmeasuring the weight and volume of the substances. The used of having the different types of liquid was to have a deeper understanding of the different densities of the respective liquids. Also,the different application on how to get the density of regularly-shaped solid and irregularly-shapedsolid were performed. In regularly-shaped solid, the use of metric ruler and beam balance wereapplied, while in irregularly-shaped solid, the use of water displacement method was applied. Thedetermination of densities of different substances was performed to have definite informationregarding different…
HISTORY OF DEHYDRATED FOODS wooden pallets or stacks of trays filled with food, with a draft system built into it to circulate the hot air. Today, the newer Natural Draft dehydrators use a 1,000-watt element for heating as its heat source, or with the electric dehydrator using nine 75-watt bulbs totaling 675-watts, plus an electric fan. TYPES OF FOODS TO BE DEHYDRATED Solar dehydration or oven dehydration are good methods for meats, vegetables and fruits. If an oven is used, make sure there are numerous drying trays to fit on the oven's racks, an accurate oven thermometer, and a small fan that is electric. The oven temperature should be 140 -degrees for up to eight hours for vegetables, fruit from four to five hours, and five hours for jerky. The 140-degrees oven heat is approximately the same heat as keeping the pilot light on, with scorching occurring if longer drying times are used.If freezing is used afterwards to kill possible insect life on the sun-dried foods, dry packing in moisture proof containers can be used. The freezer temperature needs to be below 0-degrees. Fruit: Meat: Many different foods are prepared by dehydration. Good examples are meat such as prosciutto (a.k.a. Parma ham), bresaola, and beef jerky. Fruits change character completely when dried: the plum becomes a prune), the grape a raisin; figs and dates are also transformed. Drying is rarely used for vegetables as it removes the vitamins within them, however bulbs, such as garlic and onion, are often dried. Also chilis are frequently dried. For centuries, much of the European diet depended on dried cod, known as salt cod or bacalhau (with salt) or stockfish (without). It formed the main protein source for the slaves on the West Indian plantations and was a major economic force within the triangular trade. The Process Drying methods Foods can be dehydrated by various means: the sun, a conventional oven, an electric dehydrator or a microwave oven (for herbs only). Drying, like other…
There are three methods of desalination which include, pressure, thermal, and electrical. Thermal desalination has been around since the stone ages, the water is boiled and the steam is eventually collect by leaving the salt behind. The use of an electrical fields to produce fresh water, this system uses far less energy than other methods. There's a certain phrase and technique in which they use that is called, electromechanically mediated seawater desalination. Pressure desalination also known as reverse osmosis desalination requires low pressures which in turn requires less energy. Although not widely used desalination of water could provide water by using thermal, pressure, and electrical methods.…
* Our world consists of 70% of water, from which, only 2.5% is fresh water, and 1% is drinkable water. Because of this low drinkable water rate, desalinization is a very important process which will help us provide a higher percentage rate.…
Water desalination is the removal of salts and dissolved solids from saline water (brackish or seawater), also known as Desalting or Desalinization. In addition to the removal of minerals, the process removes most biological or organic chemical compounds. Desalination systems have been used to supply potable water for coastal communities and urban centers in more than 40 countries. Desalination plants operate in almost all of the world’s oceans and seas. Desalination is the natural continuous process, which is essential for the water recycle. Precipitation, such as rain or snowfall on ground, which finally flows either in to the sea or goes back to the atmosphere through evaporation or percolates in the sub-soil is a process of natural desalination. Living beings uses this water directly from rain or from river, lakes or springs. During the travel of the surface water towards sea it dissolves minerals and other materials and becomes salty. Once it arrives to the oceans natural evaporation removes part of the water in to the atmosphere as cloud while remaining water available in the ocean becomes very salty. The evaporated water from the ocean is given back to the earth in the form of rain or snow, which again travels back to ocean and the cycle continues. However, most of this capacity is installed in the Arabian Gulf and the Mediterranean. Current installed desalination production capacity is approximately 3100 GL/yr in the Arabian Gulf and 800 GL/yr in the Mediterranean. The mineral water is one of the important items, which is directly consumed by people all over the world. Mineral water is bottled under very hygienic conditions under strict quality control being market. The consumption of mineral water gradually increase due to shortage of pure hygienic water. Desalination treatment plant make the water is filtered and treated to get rid of particles, debris, and unwanted chemicals. In…
When Joseph Stalin died on March 5th 1953, cold war tensions were at their worst. Meaningful diplomatic negotiations between the communist and capitalist adversaries had long since ended, and the nuclear arms race was entering a new and more dangerous phase. An atmosphere of hysteria and suspicion gripped the world’s two superpowers. In Moscow, ageing Stalin had spent his last days laying plans for murderous purges, while in Washington McCarthy continued his pursuit of communism.…
Have you ever wondered what it would be like to be drinking originally dirty or undrinkable water? This could be something that runs through your head in the future because desalination is a potential resolution to the loss of water. In Ken Midkiff’s book Not a Drop to Drink, chapter 7 titled “Technological Solutions: The Skyrocketing Cost of a Glass of Water” describes his outlook on the process of desalination. He also talks a lot about the technology it would take and how expensive it would be. Not only does he talk about the prices of the plants to complete the desalination, but how much the water would cost afterwards. Another thing Midkiff informs us of is that desalination isn’t always efficient. Desalination could be either a good or bad source to use in the future. It can be good because of the large amount of water that would be produced and it could be bad because of its price and inefficiency.…
