Container a (with 150mL) contains a gas with an unknown pressure. Container b (with volume 250mL) contains a gas under 628 mm Hg of pressure. Container C (with volume 350mL) contains a gas under 437mm Hg of pressure. if all these gases are put into container d (with volumer 300mL) giving it 1439 mm Hg of pressure, find the original pressure of trhe gas in the container.
Why would it be more appropriate to put the elements La and Ac in the bottom two periods and put Lu and Lr in the transition metals? Why don't we see the use of any sublevels higher than the f sublevel?
Calculate the vapor pressure of a solution containing 25.3g of glycerin C3H8O3 in 125mL of water at 30.0C. The vapor pressure of pure water at this temperature is 31.8torr}
A sample of a gas in a piston/cyclinder apparatus occupies 30.2 mL at 1.08 atm and 22.2°C. If the volume of the sample is increased to 67.3 mL and the temperature changes to 30.9°C, what is the new pressure, in atm, of the sample
Perform whatever separations and tests you think necessary to determine which ions are in fact present
Write the net ionic equation for the neutralization of the bases, magnesium hydroxide, Mg(OH)2 and aluminum hydroxide, Al(OH)3, found in Maalox, for example, with acid (H+).
A fish tank holds 30.0 gal of water. Using a density of 1.0 g/mL for water, determine the number of pounds of water in the fish tank.
A 12.0g- sample of a gas has a volume of 5.25g at 28 celcius and 757mmHg If 2.7g of the same gas is added to this constant 5.25L- volume and the temperature raised to 64 celsius, what is the new gas pressure?

Choose only the mixtures that constitute buffer solutions. Can someone how i would determine this as well? 0.30 M HOCN mixed with 0.35 M NaNO3
Why should you use a minimum amount of water to rinse the conical vial while transferring the purified acetaminoophen to the Hirsch funnel
Now suppose that an additional 5.00 moles of argon are added to the vessel, again without any change in the volume or the temperature. What is the partial pressure of argon now
