Beaker Observations 1 No scent, color is clear 2 No scent, color is foggy, oil and water don’t mix well creating bubbles. 3 No color, water is clear, smells of vinegar 4 Smells like soap, water turned green 5 80 ml of water, brown in color, dirt sediment on the bottom, smells like dirt 6 80 ml of water, less oil, light brown in color, dirt sediments at the bottom 7 80 ml of water, slight vinegar and dirt scent, brown in color, dirt sediments at the bottom 8 80 ml of water, smells of soap, dark brown and slight green in color, dirt sediments at the bottom POST LAB QUESTIONS 1. Develop hypotheses on the ability of oil, vinegar, and laundry detergent to contaminate groundwater. a.
SCI 207 NEW WEEK 2 LAB 2 WATER QUALITY AND CONTAMINATION http://www.homeworkproviders.com/shop/sci-207-new-week-2-lab-2-water-quality-and-contamination/ Lab 2 – Experiment 1: Effects of Groundwater Contamination Table 1: Water Observations (Smell, Color, Etc.) Beaker Observations 1 To me this is just water, there is no smell. 2 As you pour the oil in the water the oil started to bubble at the top. When stirring the oil turned into smaller bubbles. It looks as if the oil has placed a thick line of film on the water 3 After pouring the vinegar in the water the only change I noticed was that the water seemed to be a shade darker when added it.
| 4. | Ryan has three times as many stamps as Hal and twice as many stamps as Jimmy. If they have 220 stamps altogether, how many more stamps does Jimmy have than Hal? | 5. | Lucy and Jean have 240 stickers altogether.
Save and submit your completed Lab Report to the appropriate weekly Dropbox. Taking Screenshots The instructions below provide basic guidance on taking screenshots of your labs 1. Complete the lab step that you would like to capture in a screenshot. 2. Make sure that the window you want to capture is in the foreground.
Calculations Write out all steps of the calculations that you conducted in order to solve for the formula of the hydrate. Organization and sub-titles are important for this section of the lab report, as are units and formulas on all data used in the calculations. For example, you can use subheadings such as “Subtraction to determine the initial mass of the hydrate” to explain what is being done in each calculation and why. Discussion and Conclusion: The first part of this section of the lab is the discussion, in which you discuss any mistakes that may have been made (or what measures were taken to try to avoid mistakes) and what improvements, if any, you can think of for the procedure for the next time the lab will be conducted. In the discussion section of this lab report, you will want to discuss the importance for heating the hydrate for a sufficient amount of time.
Lab 4 – Energy Sources and Alternative Energy Experiment 1: The Effects of Coal Mining |Table 1: pH of Water Samples | |Water Sample |Initial pH |Final pH (after 48 hours) | |Pyrite |.6pH |.7pH | |Activated Carbon |.6pH |.8pH | |Water |.6pH |.7pH | POST LAB QUESTIONS 1. Develop hypotheses predicting the effect of pyrite and coal (activated carbon) on the acidity of water? a. Pyrite hypothesis = If pyrite is added to water, then the acidity of the water is neutral. b. Coal (activated carbon) hypothesis = If coal or activated carbon is added to water then the acidity of water is basic.
Lab 4 – Energy Sources and Alternative Energy Experiment 1: The Effects of Coal Mining Table 1: pH of Water Samples | Water Sample | Initial pH | Final pH (24-48 hours) | Pyrite | 4.5 | 5 | Activated Carbon | 4.5 | 6.5 | Water | 4.5 | 4.5 | POST LAB QUESTIONS 1. Develop hypotheses predicting the effect of pyrite and coal on the acidity of water? a. Pyrite hypothesis = Adding pyrite to water it will cause the pH levels to increase. b. Coal hypothesis = If I add activated carbon to the water it will lower the pH level of the water.
