The lab started off by measuring critical materials for the lab: the mass of an an empty 100 mL beaker, mass of beaker and copper chloride together(52.30 g), and the mass of three iron nails(2.73 g). The goal of this experiment is to determine the number of moles of copper and iron that would be produced in the reaction of iron and copper(II) chloride, the ratio of moles of iron to moles of copper, and the percent yield of copper produced. 2.00 grams of copper(II) chloride was added in the beaker to mix with 15 mL of distilled water. Then, three dry nails are placed in the copper(II) chloride solution for approximately 25 minutes. The three nails have to be scraped clean by sandpaper to make the surface of the nail shiny; if the nails are not clean, then some unknown substances might accidentally mix into the reaction and cause variations of the result.
Distribution of Plankton in Yellowwood Lake Introduction: Over the duration of two lab periods we collected an assemblage of plankton and tested whether plankters are actively moving or are passive in bodies of fresh water. While working in paddleboats on the Yellowwood Lake in Brown County, IN, we assembled a collection of samples of protists, rotifers, and arthropods. Before starting our study we produced a null hypothesis: plankters are passive. This null hypothesis predicts, where water is mixing uniformly, plankton distribution will be uniform (Clara Cotton, personal communication, October 6, 2016).
Our experiment was conducted in late January at Wet Beaver Creek. Wet Beaver Creek is located south of flagstaff in the Coconino National Forest. Wet beaver creek has an elevation if 1158 meters, with an average annual precipitation of 16.71 inches, and an average temperature range of 80.8 in July and 43.1 in December. Wet beaver creek features both Perennial and non-Perennial rivers, and is home to many species of trees including sycamore, Juniper, Cottonwood, Alder, Ash, and many more.
These facts introduce and support the message that Standage is delivering. Standage continues with many statistics: “Admittedly, both kinds of water suffer from occasional contamination problems but tap water is more stringently monitored and tightly regulated than bottled water. New york city tap water, for example, was tested 430,600 times during 2004 alone.” He stated. Even though he admits that both of each kind contains chemicals-which at the same time Standage claims that the tap water is more sanitized-but also he points out that it is not the taste that differs between the two
The objective of the sludge lab was to determine how many different pure substances were in the sludge by using the methods and techniques we have learned throughout the year. We had to pick separation methods so we could separate our sludge and then test characteristic properties on our separated liquids and solids. This experiment made us use our knowledge on characteristic properties to pick the ones we should test to help us identify our pure substances. Characteristic properties are properties that help identify a solid or liquid. Each solid or liquid has a certain density, boiling point, solubility, flammability, so if you know what each one is then you can use that information to help you identify your solid or liquid.
This documentary opened my eyes to many of the things that occur in my own country. I knew that politicians were looking for a way to use the resources that we have here in our own country instead of having to buy them from others, but I would have thought they would have done it while in the best interest of the people. Before watching this documentary, I was not familiar with natural gas or any of the processes that it takes to make it. I just knew that it was an efficient energy source. With any resource that we remove from the earth, we risk hurting people and many other things in the process.
From 10 bottled water brands tested by the Environmental Working Group (EWG) found “38 pollutants in total, which ran from disinfection products, arsenic, fertilizer residue, plasticizers and pharmaceuticals” (“New Study” 3). “New Study” mentions the government’s requirement on water utilities to notify of any pollutants in the water, which manufacturers of bottled water are not required to do at all. If consumers do not have any idea what’s in their water, then they cannot trust that water like they can tap water. Bottled water has multiple unseen risks associated with just drinking it.

What the vast majority don 't know is that regardless of how clear and revitalizing some bottled water might appear, the contrast in the middle of it and that of tap water is only the plastic compartment it is bundled in. This paper concentrates on issues that encompass wellbeing concerns and regulations including filtered water against tap water utilization and the chemicals that are discharged into bottled water from its plastic
Argumentative Essay: Is Tap Water Better than Bottled Water? Bottled water ranks high among the fastest growing product in the beverage market/industry around the world. In other words, the world’s consumption of the bottled water is on the increase.
Introduction: 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
Safety is the principle concern when debating this topic, especially when people think about their families’ well-being. Tap water is the champion of the two
Drinking water is an essential part of life and critical for good wellbeing. Eventually, we are comprised of 65% of water. While we are continually being instructed to drink our eight glasses of water a day, we aren't typically guided about which water we ought to trust and drink.
