Athletes that have to compete at high altitudes often go to the location and train for a month or so at these reduced pressures. This would be true of mountain climbers as well. What happens to the body that allows it to compensate (over this period of time) for the reduced pressure , so that the athletes will not become lightheaded?
A solution is prepared by mixing 85.0 mL of 5.00 M HCl and 25.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+], [OH -], and the pH for this solution.
A gas sample was collected over water at 25.3 degrees Celsius, The total pressure is determined to be 0.97 atm. What is the partial pressure of the gas that was collected?
How many grams of nitrogen dioxide (NO2) are required to produce 260 grams of nitrogen monoxide, NO?
For the reaction 2HCl+Na2CO3 →2NaCl+H2O+CO2 what volume of 0.45 M HCl solution would be needed to produce 2.5 L of CO2 at STP?
The volume of a 24.0-g sample of methane gas is 22.8 L at 40.0°C and 4.00 atm. What will its volume be at 68.0°C and 4.00 atm.
an empty aerosol can at 25 degree calcius still contains gas at 1.00 atmosphere pressure. if an empty can is thrown into a 475 degree calcius fire, what is the final pressure of the heated can?
Assume that a gold atom is shaped like a sphere. An atom of gold has a radius of 156 pm and a mass of 197 amu. Determine the density of a single gold atom in units of g/cm3. (1 amu = 1.66 x 10-24g).
What is the pH (3 significant figures to the right of the decimal point) of a 0.0500 M solution of sulfuric acid? Remember, the first ionization constant is "large,"
What mass of H2 forms if 12 grams of Zn reacts with 7 grams of HCl?
Would applying a high pressure stabilize the CsCl form, or the NaCl form of this compound? (hint: calculate the volume per formula unit)
Starting with aziridine, and using 1) PhCH2Br; 2) Na2CO3; 3) PhCH2Br as reagents, what are the mechanisms and intermediates leading to a final product
What mass of sucrose should be combined with 464 g of water to make a solution with an osmotic pressure of 8.35 atm at 320 K? (Assume the density of the solution to be equal to the density of the solvent.)
