Jack and Jill are curious about the factors that affect plant growth. They perform several experiments using pea plants (a) The leaves of the pea plants that received too much water turned yellow. (b) Jill decided that 5 hours of indirect sunlight gave optimum growth. (c) Jack gave the pea plants a controlled amount of water each day. (d) Jill thinks that too little sunlight will affect plant growth. This part please (a) Identify one variable (other than water and sunlight) that could be tested. (b) Write a hypothesis using this variable. (c) Design an experiment to test this variable.

Commercial bleaches such as Clorox are said to contain 5.25% NaOCl by weight. Is this correct? Use your results and a density of 1.0 g/mL for the bleach in your calculations. These calculations should reflect the precision of the assumed density.
Cesium chloride is used to prepare dense solutions required for isolating cellular components with a centrifuge. A 40.0 wt% solution of CsCl (FM = 168.36) has a density of 1.43 g/mL. Find the molarity of CsCl.
A 1 mL sample of glycogen was calculated to contain 35 µmol (micromole) glucose. To 1 mL of this sample was added 2 mL of 2 M HCL. It was then hydrolysed by boiling the solution for 15 minutes. After boiling the hydrolysate was cooled and made up with H2O to a final volume of exactly 10 mL. The glucose was measured in this solution and found to have a concentration of 570 µg/mL (microgram/milliliter). i) Calculate the mass (mg) of glucose in the 10 mL of hydrolysate. As the 1mL of glycogen sample was made up to a final volume of 10 mL, this mass of glucose was produced by the hydrolysis of the original 1 mL glycogen sample. ii) Calculate the amount (µmol) of glucose produced by the hydrolysis of the glycogen sample. iii) Calculate the purity of the glycogen used in the sample as % Purity = (moles of measured glucose/ moles of calculated glucose in glycogen) *100 iv) state your answer in a complete sentence.

Today the only form of liquid acetaminophen on the market has a concentration of 160 mg acetaminophen per 5.0 mL. How would you instruct parents of an infant to give a total of 40 mg of acetaminophen to their infant? Your directions should be clear, not lead to the confusion caused by the physician in the case study, and include the volume of liquid acetaminophen they should give their son. Please show how you calculated the volume needed to provide 40 mg of acetaminophen.
