A sample of air at 15 psi is compressed at constant temperature from 555ml to 275ml. Calculate the resulting pressure.
A solution is .855% HNO3 by mass. Density of the solution is 1.01 g/mL. Find [H+], [OH-], and pH.
A 0.221 g pellet of potassium hydroxide,KOH, is added to 52.2 g water in a Styrofoam coffee cup. The water temperature rises from 23.5 to 24.4 °C.
a 75.0 mL sample of potassium hydroxide, KOH, of unknown concentration is titrated with 42.5 mL of 0.575 M acetic acid. How many moles of KOH were in the sample?
if 1.205 g of KHP required 25.25 mL of NaOH solution for complete neutralization, what is the molarity of the NaOH sodium hydroxide solution?
Calculate the final temperature of the solution assuming no heat is lost to the surroundings, the final mixture has a mass of 100.0 g and the solution has a specific heat capacity of 4.18 J °C-1 g-1
The heat of neutralization of HCl by NaOH is H°rxn = -56.2 kJ/mol. How much heat is released when 125 mL of 1.750 M HCl is mixed with 195 mL of 0.667 M NaOH.
A sample of gas with a volume of 750 mL exerts a pressure of 98 kPa at 30 ?C.What pressure will the sample exert when it is compressed to 250 mL and cooled to -25 ?C?
The solubility of N2 in blood at 37°C and at a partial pressure of 0.80 atm is 5.6 10-4 mol/L. A deep-sea diver breathes compressed air with the partial pressure of N2 equal to 3.6 atm.
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.
Metals Covalently Bonded to Benzene, I've noticed that my book does not mention metals as a possible substituent for mono-substituted benzenes, but it doesn't begin to explain why
Consider an experimental run at 273k where the initial number of moles is actually 1.00 , and the final number of moles is 2.00 . Use the simulation to find the volume of 1.00 of helium at 273k and calculate the final volume.
.At 25°C and 1.0 atm, 0.25 g of a gas dissolves in 1.00 L of water. What mass of the gas dissolves in 1.00 L of water at 25°C and 3.0 atm?
