A 290-mL flask contains pure helium at a pressure of 742 torr. A second flask with a volume of 465 mL contains pure argon at a pressure of 718 torr.
If the two flasks are connected through a stopcock and the stopcock is opened, what is the partial pressure of helium?
what is the freezing point(Degrees C) of a solution prepared by dissolving 11.3g of Ca(NO3)2 ( formula weight= 164g/mol) in 115g of water?
White phosphorus is a molecular solid made of molecules of P4. A 3.05 g sample of white phosphorus starts at 20oC. Calculate the amount of heat (in J) required to melt the sample.
Hydrogen gas was collected over water in a eudiometer at 25 C when the atmospheric pressure was 752 mm Hg. What was the pressure of the hydrogen gas?
What is the purpose of running both Dalton Vll mixed markers and lanes with individual markers on SDS-PAGE?

What is the Molarity of Phosphoric acid stock used to make 750 ml of dilute 4 N soludtion if 52 ml of concentrated solution was use
A beaker with 1.70×102 mL of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 6.20 mL of a 0.490 it M HCl solution to the beaker. How much wi..
Calculate the pH and the percent ionization of butanoic acid in this solution. *I will only award points if a solution is presented. What good does just the answer do for me?
A 486 mL sample of water was cooled from 50.0°C to 10.0°C. Assuming a specific heat of 4.184 J/K g and a density of 1.00 g/mL, find the amount of heat transferred from the water to the surroundings.
