Use the acidity model pH = −log[H+], where acidity (pH) is a measure of the hydrogen ion concentration [H+] (measured in moles of hydrogen per liter) of a solution.Find the pH when [H+] = 4.7 × 10−5. (Round your answer to two decimal places.)pH =

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)
