Biological organisms live at great depths in the ocean and they have adapted their bodies to survive at extreme temperatures and pressures in the dark. One of the adaptations is to equilibrate their internal pressure with the external pressure.
a) Calculate the hydrostatic pressure at a depth of 2000 m. Express your answer in atm.
The density of ocean water is 1.025 kg/L.
b) Let's model an organism as a balloon filled with O2. At 1 atm pressure, the balloon has a volume of 1 L. What is the volume of the balloon at a depth of 2000 m? The temperature at a depth of 2000 m is 4 ºC.
c) State one adaptation the organism would have to make to survive these conditions.
Treatment of A with zinc amalgam and HCl affords an optically active, dextrorotatory hydrocarbon C. Identify compounds A, B, and C, including stereochemical configurations. Be sure to explicitly draw H and both wedge/dash bonds at any configuratio..

A mass of G grams of a liquid are placed in a closed 15 liter, fixed-wall container. The molecular weight of the liquid is 18 g mol-1. Its molar heat of vaporization is 44 kJ mol-1. Its normal boiling point is 373 K. A scientist measures the press..
What are the products from the combustion of 2-methyl-3-ethyloctane?
PH And Percent Ionization, 1. Determine the pH and the percent ionization in a 0.50M solution of KOBr. The Ka for HOBr = 2.5 x 10 ^ -9.
At what temperature will He atoms have the same Crms value as N2 molecules at 25 degrees Celsius? Solve this problem without calcularing the value of Crms for N2. Crms is the root mean square speed.
What is the pH of the solution when the titration is half way to the end point?
what advantage does using the Wiley extractor have over simply pouring acetone over the meat again and again?
How many moles of excess base are present? How many additional mL of 0.100 M HCl would be required to neutralize the solution?
A bicycle tire is filled with air to a pressure of 611 kPa at a temperature of 19 degrees C. Riding the bike on a hot day increases the temperature of the tire to 58 degrees C.
At a certain temperature and pressure, 1.3L of reacts with 3.9L of H2. if all the N2 and H2 and are consumed, what volume of , at the same temperature and pressure, will be produced
Assume that an air conditioner consumes 1.50 X 103 W of electrical power, and that it can be idealized as a reversible Carnot refrigerator. If the coefficient of performance of this device is 2.50, how much heat can be extracted from the house in ..
