Water Synthesis Essay

Water: a necessary facet to all living things. For animals, water can be a home or a drink. As for humans, the uses of water are endless. Not only do we use water as a beverage or washing clothes or dishes, but we also use water for toilets, various kinds of plumbing and other things that aren’t as easily identifiable. As of 2005, this 70% of our Earth has been manipulated and used for thermoelectric power (41.5%), irrigation (37%), domestic affairs (8.5%), public supply (5.4%), industry (5%) and aquaculture (2.6%).1 The importance of water is infinite, not only to our way of life, but also our lives. We need to drink water to ensure the health of individual cells of the body, lubricate joints, moisten mucous membranes of the organs and many other vital bodily functions.2 Not only do we expect the availability of water, but it is highly important to humans and all living things. Although it is such an integral part of our Earth, one may ask about some of its properties and characteristics.

You can check the hydration status of your patient by checking the skin turgor of the patient. Pull the loose skin over the neck, also known as the scruff, release the skin and it should snap back if the patient is hydrated. If the patient is not hydrated you’ll determine the hydration status by approximately how many seconds it takes for the skin to retract. Another way to check the hydration status is to evaluate the capillary refill time, the CRT is typically 2 seconds or less. Press firmly on the gums and count how many seconds it takes for the color to return. The longer it takes for the refill time usually is an indicator of low cardiac output, 2 seconds or less means high cardiac output. Our 8 lb. feline is presented with 10% dehydration but

Figure 1 shows the relationship between the percent change in mass and the molarity of sucrose solution for both group data and class average data. The percent change in mass was used instead of just change in mass because all of the bags had different initial masses. The percent changes allowed comparison between the different solutions. The smallest percent change in mass was in solution C, which had a molarity of 0.0M. The greatest percent change in mass was in solution B, which had a molarity of 1.0M. Discussion/Conclusion:

Coupland here at Penn State. He is currently studying effects of these colloid suspensions with the discipline of food chemistry, applying his findings to applications of many sorts. In general, Dr. Coupland does not focus his research on creating or modifying a specific emulsified food, for example mayonnaise. Instead, he studies how the physical structures of food products are affected, which encompasses an overall study of emulsions in a immense array of foods. However, emulsions are ubiquitous in the world of food, coming in many shapes and sizes; therefore, Dr. Coupland has narrowed in on mainly oil in water emulsions, where water surrounds microscopic fat droplets to increase viscosity and alter various other physical properties. As a whole, the research being conducted by Dr. Coupland impacts food product, pharmaceuticals, etc. to a great degree, broadening the current viewpoints of the

Experiment Title:How Dense Is This Substance? Name(s):Praventh. R Purpose: Is this liquid/substance greater than or less than 1g/mL? Will the liquid/substance be highly viscous or will it have a low viscosity?

Did you shower or brush your teeth in the last three months? Some people without H2O in their homes haven’t.California is in a serious drought and at least 1,300 people have lost their house aquifer in and around East Porterville due to this outrageous tragedy.California should manage wells and aquifers.

The experiment was divided into two parts. Part A was to recover the copper metal using the copper cycle method and part B was to observed copper (I) compounds. Every copper complexes and compounds indicated in the experiment was observed very carefully. Any chemical changes in each step were recorded at instant. Such as, In Part B copper (II) nitrate was combined with sodium hydroxide to form an light blue precipitate of copper (II) hydroxide which upon heating, gives us a black colored precipitate of Copper (II) oxide.

It is no secret that criminals are always in search of means to effectively destroy any evidence that may implicate them in a crime, particular involving friction ridge skin as it is often speculated to be the most damning form of of evidence that exists. This is due to the undeniable uniqueness of fingerprints that remain unchanged throughout a person’s lifetime (Holder, Robinson & Laub, 2011). Over time efforts to destroy friction ridge skin evidence have included methods of water to wash away the latent print evidence, not a shocking concept once we think about how vast bodies of water occupy over 70% of the earth’s surface (Williams, 2014). Therefore, as a means to examine the effects of water submersion on latent fingerprints, an experiment was conducted to identify the impact four variants of water solutions have on latent fingerprints.

In this project we will determine the viscosities of 5 separate liquids. The liquids we will test are corn syrup, honey, vegetable oil, milk, and water. We will find their viscosities by dropping a marble into each of these liquids and measuring the time it takes for it to reach the bottom.

An ice bath was prepared in a large beaker and a small cotton ball was obtained. 0.5 g of acetanilide, 0.9 g of NaBr, 3mL of ethanol and 2.5 mL acetic acid was measured and gathered into 50mL beakers. In a fume hood, the measured amounts of acetanilide, NaBr, ethanol and acetic acid were mixed in a 25mL Erlenmeyer flask with a stir bar. The flask was plugged with the cotton ball and placed in an ice bath on top of a stir plate. The stir feature was turned on a medium speed. 7mL of bleach was obtained and was slowly added to the stirring flask in the ice bath. Once all the bleach was added, stirring continued for another 2 minutes and then the flask was removed from the ice bath and left to warm up to room temperature. 0.8mL of saturated sodium thiosulfate solution and 0.5mL of NaOH solution were collected in small beakers. The two solutions were added to the flask at room temperature. The flask was gently stirred. Vacuum filtration was used to remove the crude product. The product was weighed and a melting point was taken. The crude product was placed into a clean 25mL Erlenmeyer flask. A large beaker with 50/50 ethanol/water

This experiment consisted of a simple distillation of a hexane and heptane mixture. The first, third, and fourth fraction were taken and recorded in Table-1. The first fraction temperature ranged from 29.7°C – 38.2°C. The second fraction temperature range was recorded as 40.3°C-41.7°C, but this fraction was not used. The third fraction temperature range was determined to be 41.8°C – 36.5°C. Finally, the fourth fraction temperature range was 34.5°C-27.3°C. The ranges of the temps following the second fraction began to decrease, causing a discrepancy in the data. This decrease in data can be linked to the formation of water or condensation on the tip of thermocouple. The first, third, and fourth fractions were collected and further analyzed using

Clean water supply is essential in establishing and maintaining a healthy community. There are two sources of water supply which are the surface water and ground water. Most natural waters are not suitable for consumption as it is contaminated by pathogens and also natural chemicals and minerals. In addition, as a city grew, wastes from human activities contaminate most of the water supplies. Water treatment plays an important role to properly treat a contaminated source of water supply in order to protect the health of consumers. Water treatment process is defined as a process of eliminating pollutants from untreated water to produce a biologically and chemically risk-free water, which is both potable and palatable for human consumption

I did this project because I wanted to know what viscosity was.Also I wanted to know how to measure it. Viscosity is the thickness of a liquid, and also what makes a liquid flow slower or faster. For example milk and honey. Honey would be thicker than milk so the honey would flow slower than the milk.

Corpus Christi does not have much, but it is popular for a number of things. There is the Lexington, beaches, ship ports, a nearby base, a big university, a Salina statue, and contaminated water. Contaminated water nonchalantly being thrown in there is no joke. Corpus Christi water problems are a nuisance. Water problems in Corpus Christi are a burden to residence, can lead to health risks, and over all looks bad on the city’s part.
