It occurs when gases such as nitrogen (N₂) come out of solution in the blood. This can lead to symptoms including joint pain, shortness of breath, and paralysis. Severe cases may result in death. a What type of molecule (ionic, polar covalent, nonpolar covalent) is nitrogen gas? b The liquid medium of blood is water. What type of compound (ionic, polar covalent, nonpolar covalent) is water? c What happens when molecules such as nitrogen gas mix with water? How does this explain the problems we see with decompression sickness?

In this experiment Lavoisier found that mercury(II) oxide, when heated, decomposed into liquid mėrcury and an invisible and previously unknown substance: oxygen gas. 1. Write a balanced chemical equation, including physical state symbols, for the decomposition of solid mercury(II) oxide (HgO) into liquid mercury and gaseous dioxygen. 2.…

A pheromone is a type of volatile compound produced by a variety of insect species for chemical communication. These molecules can be used to signal alarm, to attract a mate, or to indicate the presence of food. The presence of 1.00 x 10-8 g of a pheromone can be sensed by another insect within a radius of 0.500 miles. Calculate the density of this pheromone. (1609 m = 1 mile) %3D Calculate the density (g/L) of the pheromone in this cylindrical air space.

You have a 11.5 mg sample of blood that contains various proteins. Hemoglobin is the only protein in the sample containing Fe. Hemoglobin contains 3.83% by mass of a compound called heme (C₃₄H₃₂FeN₄O₄, MW = 616.49 g/mol). You find that your 11.5 mg blood sample contains 27.1 micrograms of Fe. What is the mass percent of hemoglobin in your protein sample?

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)
