Water Essay

A water molecule is made of two hydrogen atoms and one oxygen atom. Oxygen and Hydrogen are gases but when combined form into a liquid compound; water. The hydrogen atoms make an angle of around 105 degrees with the oxygen atom. The oxygen atom dominates an end of the molecule while the hydrogen atoms dominate the other. The asymmetry of the water molecule causes the oxygen end to have a slight negative charge while the hydrogen end has a slightly positive charge. A molecule with both (-) and…

amount of zinc in vitamin water had to be determined. To do this, three methods were applied. The first was by a calibration plot method, where zinc standards were prepared and from the absorbance of those standards a calibration curve was plotted, which in turn was used to determine the amount of zinc in vitamin water. The second method was standard addition. For this method, an un-spiked and spiked solution were prepared. The un-spiked solution only contained the vitamin water, while the…

I am against the use of chloramines in Stockton’s water. Did you know that it can cause rashes after showering in a small percentage of people? (http://www.foodreference.com/html/a413-chlorinewater.html, Article 3, Paragraph 4) What if that small percentage is you, everyone else is just fine and you are suffering from this rash. It’s also possible for lead from pipes to dissolve into the water, which can cause even more problems. (http://www.foodreference.com/html/a413-chlorinewater.html,…

Water is how everyone lives, even plants, animals, and of course humans. Well what is a water cycle? Precipitation is how the water cycle starts, it is how water moves through the earth. The water from the Earth is always in movement, and the Earth's water cycle, also is known as the hydrologic cycle. This describes all the movement of the water, above and below on Earth's surface. The water cycle describes a continuous pattern of exchanged water having the cycle over and over again. Lakes,…

half-full with tepid water. Put it on the hotplate and raise the temperature to 98 degrees. Make sure you can keep it at this temperature for several hours. 2. Wash your hands. Cover the surfaces adjacent to your kitchen stove with paper towels. Place the test tube racks close to the stove on the paper towels. 3. Fill the pot with water and bring to a boil. Uncap your test tubes. Using your kitchen tongs, carefully drop your graduated cylinder, test tubes and their caps in boiling water. Boil…

With only 71 percent of the earths body of water, we have 96.5 percent of ocean resources to meet our current expectations of having a blissful experience along the coastlines. Although this may be true, lately we as consumers are destroying our oceans sustainable body of water, and the sea creature’s life expectancy. Henceforth in the county of Los Angeles specifically, the sustainability of ocean waters are being contaminated by the toxicity of waste being dumped by consumers. Under the…

Water fluoridation is an addition of the chemical fluoride to public water supplies, for the purpose of reducing cavities. Fluoridation is the addition of small quantities of fluoride to public water supplies. It is a kind of mass medication and the only chemical added to water in quantities over that of naturally occurring water. A small quantity this chemical does not have any significant negative effects on our body, however over consumption can make it poisonous and in severe cases can be…

Unit 16 – P1: Cold water: Indirect cold water: This type of water system comes through the house through the rising main. Then the water gets separated up to a 24 hour storage cylinder, from here is where the water gets sent back down to all of the appliances that require it apart from the kitchen sink. This is because the kitchen sink is fed water by a direct water source due to it being used for food prep. An advantage of using indirect cold water is if the main supply gets cut off you…

In this lab we will be testing the water quality of the Lewis and Clark Lake. We will be testing to see if the water is good quality and good for the fish and creatures that need that water to live. The first step is to extract the water from the lake and analyze the way it looks. We should write down the description of the water. The second step is to take it to the lab to test the water for pollutants and to test the quality of the water. Ph. is a measure of the hydrogen ion concentration of…

Water is one of the best and one of the most important too tall of the biological systems. Water doesn’t not only exist in the 3 states of matter which are, solid liquid or gas. Water covers just about 75 percent of the earth and is throughout 78 percent of the human body. Without water there are any things that we would not be able to do. We would not be able to travel from place to place to go on cruises and we would no longer be a beach or water to drink. We would no longer be able to shower…
