Ecological Interactions EXPERIMENT 1: ECOLOGICAL INTERACTIONS Data Tables Table 2: Volume and Concentration Totals Trophic Cylinder oil Volume of Level 1st 2nd 1000 mL 100 mL Post-Lab Questions What does the water in this experiment represent? What does the oil represent? 1. 2. How did the amount of oil change from one trophic level to the next? 3. How does the change in the amount of oil relate to biomagnification? 4. Why would this change in amount of an accumulating...
1. Short Answer: How does the change in concentration of oil represent biomagnification? 2. Multiple Choice: How does this also illustrate the amount of energy transferred from one trophic level to the next? A.) The volume of oil increases with each transfer as energy increases because 100% of the energy is transferred from one trophic level to another. B.) Only a percentage of the original 10 mL of oil is transferred at each level as only a percentage of the...
Use the 100 mL graduated cylinder to measure and pour 50 mL of distilled water into Beaker 1. Use the 100 mL graduated cylinder to measure and pour 48 mL of distilled water into Beaker 2. Use the 10 mL gradated cylinder to measure and pour 1 mL of saturated sodium bicarbonate solution into Beaker 1. Then, add 2 drops of phenol red to Beaker 1. Gently mix the solution. Use the straw to blow bubbles into Beaker 1. Start...
EPORT FOR EXPERIMENT 3 (continued) NAME 4. A 100-mL graduated cylinder is filled to 26.4 mL with water and placed on a balance. The balance reads 45.20 grams. An irregularly shaped metal object of unknown compo- sition is placed in the graduated cylinder and the water level rises to 32.3 mL. The scale now reads 88.21 grams. Use Table 3.2 to identify the metal used to make the object. 5. Use your own words to define the terms "extensive property"...
Sig. Figs Question #1 A) A graduated cylinder contains 18.0 mL of water. What is the new water level after 35.6 g of silver metal with a density of 10.5 g/mL is submerged in the water? B) How many cubic centimeters (cm3) of olive oil have the same mass as 1.00 L of gasoline? density: olive oil = 0.92 g/mL, gasoline = 0.66 g/mL c) The area of a triangle is 67.4 in2. Convert this area to cm2. (1 inch...
ACTIVITY ACTIVITY 2 A Determining the Densities of Solutions 1. Weigh an empty 50-ml graduated cylinder. Record the mass in Data Table 2. 2. Add 5 mL of water (0% sucrose) to the 50-ml graduated cylinder. Use the pipet to add or remove small quantities of liquid so that the water is exactly at the 5-mL mark. 3. Record the Mass of Solution + Graduated Cylinder in Data Table 2. 4. Add more water until the cylinder contains 10 mL...
Fill the graduated cylinder with hot tap water and let stand for one minute. Pour water into the sink. Measure 70 mL of hot water. Pour the water into the foam cup. Measure the temperature of the water. Add an ice cube to the cup of water. Gently swirl the cup. Measure the temperature of the water as soon as the ice cube has completely melted. Pour the water into the graduated cylinder and measure the volume. The initial temperature...
You need 100 mL of a 0.00057 M solution for an experiment. You are given 10 mL of a 5.7 M stock solution. What is the best method to get the final volume and concentration you for trial? -It is not possible to reach that concentration with the info presented. -Use a 1.0 mL volumetric pipette and then dilute with water to 100 mL, then repeat serially until the desired concentration is reached. -Use a graduated cylinder to measure 0.1...
I need the density (g/mL) for the water column and the isopropyl alcohol column. With math shown and included please! The question requires me to show work. If possible, I would also like the percent error's (with work shown) of the water and isopropyl alcohol columns. Thank you! Part 1: Volume and Density Measurements (Liquid) 1 Gather the graduated cylinder, distilled water, short stem pipet, and isopropyl alcohol. 2 Place the clean, dry, 25 ml graduated cylinder on the tared...
