23.23 The following dissolved-oxygen values were found after 5 days of incubation in 305-mL BOD bottles: 8.2, 8.0, and 8.1 in three blank samples and 7.4, 6.5, 4.9, 1.5, and 0.0 mg/L in bottles containing 0.5, 1, 2, 4, and 8 mL of sample, respectively. The 0-day dissolved oxygen of the sample was 6.5 mg/L. What is the 5-day BOD of the sample?

Gases You should be able to answer this prompt using 10 sentences or less. Gases are very important for life in terms of respiration and photosynthesis. However, gases play other critical roles in our daily lives. Think about the past month. Did you use any product that is a gas at room temperature? What was the product or substance? State one chemical or physical property of the substance that is unique because it is a gas.
Why are ducks waterproof? It’s because they produce copious amounts of oils from their uropygial glands and spread it across their feathers. In this exercise, we’ll be investigating the molecular structure of one of these preen oils to determine how it keeps ducks dry. Q.5 - Preen oil is actually a complicated mixture of many different organic compounds, such as the structure seen previously.. Ornithologists have determined that birds often use preen oil compounds for scent recognition. Below, several different chemicals isolated from preen oil are shown, along with their vapor pressures at room temperature. p-cymene has the highest vapor pressure, meaning it is the most easily evaporated compound of the three listed. Explain why p-cymene has a higher vapor pressure at room temperature compared to the other compounds. Make sure to explain what holds the p-cymene in the sample. (Image attached)
