a)Describe an experiment to test whether soil pH affects the growth rate of sunflowers. Include all of the following: hypothesis, predictions, controlled variables, independent variable, dependent variable. b)If your experimental data support your hypothesis, what are some next steps that you can do? c)What is a control and why are controls critical to experimental design? d) Why is the dependent variable important to any study?

Goofy Incorporated bought a sizeable amount of Crazy Company's bonds for $200,000 on May 5, 2023, and classified the investment as available-for-sale. The market value of the bonds declined to $124,000 by December 31, 2023. Goofy reclassified this investment as trading securities in December of 2024 when the market value had risen to $163,000. What effect on 2024 net income should be reported by Goofy for the Crazy Company bonds? A: 39,000 net unrealized holding gain B: 37,000 net unrealized holding loss C: 76,000 net unrealized holding loss D: 0

Convert each "b" value from the three Graphs ln(Conc) to the Initial Concentration. Graph Two:  y= -0.0048x -11.125 Graph Four: y= 161824x - 13.326  Graph Five: y= -0.0189x -10.903  **Note these are the y= mx-b equation from the linear graph,  In(concentration) vs time. I don't know how to convert natural log value such as -11.125 to the initial concentration.

We are doing an experiment on measuring the temperature. We are to measure the temperature of hot water (measure it initially, then wait for 10 minutes then measure again). Additionally, we are to measure the temperature of another water before and after putting ice (measure initially then measure 3 times [every 5 minutes] for 15 minutes). My question are: What law or principles of chemistry could be applied in this experiment? Should we expect the temperature of the hot water to drop? why? Should we expect the temperature of the water to rise or drop after putting the ice? why?

Once you have completed your chemistry experiments, either by producing products or leaving reagents behind, you must put these substances into the appropriate chemical waste container. The list of items below includes those that will be used in your labs and are thus considered "waste." From this list, select the correct location to deposit each substance once it has been deemed Waste: (match the number on the right with the waste on the left, there will be one number that is not used in the matching) Bromoacetone(1) 1. Inorganic acids and salts 2. Inorganic bases > NaCl(aq) HCl(aq) Acetone(1) Cu(s) NaOH(aq) 3. Solid waste 4. Organics 5. Halogenated Organics 6. Pour down the sink 7. Garbage pail

Ms. Tan came to the laboratory for blood tests because her physician suspected renal disease. The tests ordered were serum BUN, creatinine, and electrolytes. The blood specimen was obtained and processed. When the laboratory scientist received the serum to perform the tests, he noticed that the serum had a reddish tinge. What factor/s could cause this to happen to a serum specimen?     2. Is the sample acceptable for use? Elaborate your answer   3. What are the advantages of using plasma compared to serum in chemical analyses?
