In order to dive, the sphere takes on mass in the form of sea water. Assuming ideal behavior, what is the partial pressure of helium?Ī bathysphere used for deep sea exploration has a radius of 1.50 m and a mass of 1.20 × 104 kg. The concentration (𝑛/𝑉) of the mixture is found to be 0.150 mol/L. use the ordered pairs (8,400) and (40,1700) to determine the average rate to lower the bellĪ mixture of helium and neon gases at 317 K contains 3 times the number of helium atoms as neon atoms. after 40 minutes the bell is at a depth of 1700ft. after 8 minutes, the bell is at a depth of 400 ft. If she were to hold her breath as she ascends to the waters surface a)by how many times would the volume of her lungs change assuming the waterĪ deep sea diving bell is being lowered at a constant rate.
#721 MMHG TO ATM SKIN#
Lucy is going skin diving to see coral off the coast of Mexico in sea water with a density of 1025 kg/m^3. 12,000 A submersible can dive to a depth of What is the unit rate of change for this problem situation? A.
With her parachute open, she descends from 12,000 feet at a rate of 13 feet per second. Given the molecular weight of helium is 4.0 g/mol, how many moles of helium does it contain?Ĭaroline is sky diving. If a tank of Trimix 10/50 has a total pressure of 2.07 x 10 4 kPa, then what is the partial pressure of helium?Ī helium balloon contains 0.54g of helium. Trimix 10/50 is a gas mixture that contains 10% oxygen and 50% helium, ant the rest is nitrogen. Millions of undiscovered species live, in the Scientists report (1) that creatures living in the deep sea are in danger of starving to death. We have to rewrite this correcting fragments and run on sentences can someone check my work below the original. Water toys Is the answer B? ThanksĪ deep-sea exploring ship is pulling up a diver at the rate of 25 feet per minute.
When diving into water, it is important to look before diving to avoid (blank) that could damage your nervous system. His altitude (in meters relative to sea level), xxx seconds after diving, is modeled by: d(x)=1/2x^2 -10x What is the lowest altitude Rui will reach? I actually don't understand this problem if its asking for
#721 MMHG TO ATM PROFESSIONAL#
Rui is a professional deep water free diver. If the partial pressure of cyclopropane in the mixture is 334 mmHg and the partial pressure of the oxygen is 1.02 atm, what is the total pressure of the mixture in torr?Ĭalculate the total pressure (in atm) of a mixture of 0.0300 mol of helium, He and 0.0200 mol of oxygen O2 in a 4.00 L flask at 20 degrees C. What is the composition of the mixture by volume?Ī cyclopropane-oxygen mixture is used as an anesthetic. 1.How many atoms of oxygen are present in the mixture? 2.How many grams of manganese are in the mixture?Ī gas mixture composed of helium and argon has a density of 0.846g/L at a 734mmHg and 298 K. Which may be a result of rising seaĪ mixture contains 0.250 mol of Mn2O3 and 20.0 g of MnO2. Creatures in the seabed are suffering from growing food shortages. Millions of undiscovered species live, in the deep sea.
Scientists report (1) THAT CREATURES LIVING IN THE DEEP SEA ARE IN DANGER OF STARVING TO DEATH. What is the partial pressure of oxygen when this mixture is delivered at a total pressure of 8.0 atm? This is a new chapter A heliox deep-sea diving mixture contains 2.0 g of oxygen to every 98.0 g of helium.
