Water Purification Lab
The overall purpose of this lab was to develop a lab procedure in order to separate and measure the mass of each containment obtained the provided sample.
In addition, this experiment was conducted in order to provide the EPA with a plan to remove all contaminants from a heterogenous mixture which purifies the water, making it accessible for the society. Furthermore, the sample consisted of the following contaminants, sand, rock, wood, plastic, salt, water, and an unknown metal. When it came to separating the contaminants, the wood and plastic were taken out through the use of tweezers, while the rocks were separated by decanting the mixture of sand and rocks from the water. Also, once the rocks had been filtered out, the sand was separated by the

All things considered, the results proved that the unknown substance or element was barium since the calculated density was 3.9 g/mL. To expand upon, the density was calculated by measuring the mass of the metal and using the displacement method to determine the volume of the metal. Also, the best method of disposing the storm water would be to contact a Wastewater Treatment Plant (WWTP) so that they could put it through a purification process, making all that water reusable. Meanwhile, the percent of recovery was calculated by the formula Percent Recovery=observed valuetrue value *100%. Furthermore, according to the pie chart created in the data analysis, the sample given contained of the percent by mass for metal to be 5.2%, salt was 3.3%, wood was 3.1%, plastic was 4.5%, rock was 12.5%, sand was 11.8%, and water was 59.6%. Also, the formula used to calculate the percent error was Percent Error=observed value-true valuetrue value*100%. When it came to the results, the calculated percent error was 6.65% for sand, 0.60% for wood,1.57% for plastic, 3.13% for metal,

Miracle Gro Osmosis Lab
453 Words | 2 PagesThe experiment we did was a lab to discover how “Miracle Gro” affected the germination of seeds. My group’s original hypothesis was that the seeds with the highest concentration of “Miracle Gro” would grow the most compared to the other seeds. However, after 8 days, the results were the exact opposite; the seeds that got 0% of “Miracle Gro” turned out to be the healthiest and tallest. By the third day, all five seeds, for the water solution, where sprouting. On the other hand, the solution with 4% “Miracle Gro” only had 3 seeds starting to sprout.
Stinky Cove Research Paper
1724 Words | 7 PagesWe walked along the beach a little more and talked and looked at the location of a whale skull that used to be buried in the sand. The rock was actually much smoother than . We also took a look at some possible bones and skeletal remains along with concretions. The concretions were rather large comparable to smart car in size. Concretions are solid masses formed around some type of matter that will change the chemistry of the rock slightly, helping it become harder and less susceptible to erosion.

606 Words | 3 PagesThe book starts off with a boy named Russell banks moving next to a boy named Joey banks. Russell is a normal boy with a normal family however, Joey has an abusive dad due to this constant trouble making followed with two sisters that he doesn't get along with very well. Russell and Joey soon become friends and quickly start getting into mischief together. Through this behavior Russell and Joey start to shape the theme of the story.
Compare And Contrast The Separation Of Copper Chloride And Sodium Chloride Mixture
1371 Words | 6 PagesAbstract In this experiment the separation of a copper (II) chloride and sodium chloride mixiture was attempted. The main aim was to separate the compounds from eachother while receiving as much of the original mass of both substances as possible - in perfect conditions the original mass will be received after seperation. Many techniques were considered but dissolution, filtration and evaporation proved to be easiest and most reliable in a school environment with school equipment. The copper (II) chloride and sodium chloride mixture was dissolved in a methanol solution and filtered out leaving the sodium chloride behind.

631 Words | 3 PagesIn this lab there were five different stations. For the first station we had to determine an unknown mass and the percent difference. To find the unknown mass we set up the equation Fleft*dleft = Fright*dright. We then substituted in the values (26.05 N * 41cm = 34cm * x N) and solved for Fright to get (320.5g). To determine the percent difference we used the formula Abs[((Value 1 - Value 2) / average of 1 & 2) * 100], substituted the values (Abs[((320.5 - 315.8) /

Lab Report: The Incredible Egg
918 Words | 4 PagesThe Incredible Egg The purpose of this lab was to find out what would happen over time to weight of an egg after we scrubbed the eggshell off in a little spot. We then soaked it in water for 10 minutes, 30 minutes, 24 hours and measure how much the weight went up. Once we came back the next day we measured them after 24 hours. In the same day we put the syrup in the cup instead of water and we measured how much it weighed after 10 minutes, 30 minutes and 24 hours. As we did this with the water the weight of the egg went up because the water soaked into the egg and made it heavier.
King River
439 Words | 2 PagesKing River, Tasmania Outline the physical features of the King River. The river in Western Tasmania is made by two rivers, Eldon and South Eldon, coming together. It flows down for 52km to Lake Burbury where it goes through a tunnel to a power station. Along the sides of the river you can find huon pines - a type of plant native to Tasmania. The top part of the river lies in a glaciated valley and is surrounded by mountains.

Copper Recovery Lab Report
471 Words | 2 PagesThe percent recovery of the copper was calculated using the equation, percent recovery = (the mass of the copper recovered after all the chemical reactions/the initial mass of the copper) x 100. The amount of copper that was recovered was 0.32 grams and the initial mass of the copper was 0.46 grams. Using the equation, (0.32 grams/0.46 grams) x 100 equaled 69.56%. The amount of copper recovered was slightly over two-thirds of the initial amount.

603 Words | 3 PagesIntroduction: In this lab, of water in a hydrate, or a substance whose crystalline structure is bound to water molecules by weak bonds, is determined by heating up a small sample of it. By heating, the water of hydration, or bound water, is removed, leaving only what is called an anhydrous compound. Based on the percent water in the hydrate, it can be classified as one of three types: BaCl2O ⋅ 2H20, with a percent water of about 14.57%, CuSO4
Tap Water Research Paper

We all know our water supplies have been contaminated for years, but the governmental regulating bodies like the Environmental Protection Agency and the Food and Drug Administration have, in the past, consistently declared that low levels of these contaminants pose little threat to us. In this article we will look at what the experts are now saying about this and how you can protect your family from danger. Past government statements concerning the health risks of contaminants such as chlorine, fluoride, pharmaceutical drugs, toxic chemicals, etc. were based on their effects on adults,
