A) What pressure would it take to compress 150. L of helium gas initially at 1.00 atm into a 2.00 L tank at constant temperature?
Express your answer with the appropriate units.
B)A balloon filled with 2.00 L of helium initially at 1.55 atm of pressure rises into the atmosphere. When the surrounding pressure reaches 490. mmHg, the balloon will burst. If 1 atm = 760. mmHg, what volume will the balloon occupy in the instant before it bursts?Express your answer with the appropriate units.
When 4.00g of hydrogen nuclei fuse to form helium in the sun, 0.0265g of matter is converted into energy. Given that the speed of light = 3.00x10^8 m/s and that a jolue = kg*m^2/s^2, calculate how much energy is given off.

Dissolve a compound with a molecular mass of 272.05 in a 10-mL volumetric flask. You remove a 1.00-mL aliquot, place it in a 25-mL volumetric flask and dilute it to the mark.
I need 1 page about How gas is pressurized and how gas is projected from aerosol cans. I need just a page from scholarly sources only. You said in chat you can do it in 2 hours.
in the reaction pbno32 hcl ---- pbcl2swhy does the precipitate disappear when h2o is added? it is pushing the reaction
A pure fluid is described by the following expression for Gibbs free energy: G = gamma(T) + RTlnP, where gamma(T) is a substance specific function of temperature.
Cyanogen is a gas which contains 46.2% C and 53.8% N by mass. At a temperature of 25C and a pressure of 750 mm Hg, 1.50 g of cyanogen occupies 0.714 L. What is the molecular formula of cyanogen
Problem- Assume that the Pit down forger has also used group 1 and group 2 cations to stain the bones. How could this potentially affect your results?
The sugar (sucrose, C12H22O11) is purchased from a sugar farmer who used to be a chemist and who packages it by the lbmol, and the process uses 1.75 lbmol/hr.
