Hey i dont really know what forum this should go in. I have 2 questions on a review thing and i cant find anyone that knows how to do them.. i added 20 bucks to paypal but i need to wait until Jan 6 for the funds to be added. if you can answer these (10 bucks each) by tonight ill send money on Jan 6 email if you are interested. padresfan994@aol.com

might help if you included questions..?

id like to do this over email. its finding pressures of gases and such. send me an email and i will email you the questions. id appreciate the help.

in case my teacher decides to randomly google the questions he put on a take home test.....

Just fucking post them. Don't know if I'll be able to do them, but I'm not emailing you.

Word them differently?

Or change values or something.

Equal Masses (0.250 g each) of hydrogen and oxygen are placed in an evacuated 2.00 L flask at 25.0 Celsius. The mixture is allowed to react to completion and the flask is returned to 25.0 Celsius and allowed to come to equilibrium. The equilibrium vapor pressure of water at 25.0 Celsius is 23.76 torr.

Write a balanced equation for the reaction

What is the total pressure inside the flask before the reaction begins?

What is the mass of water vapor in the flask at equilibrium?

How many grams of which reactant gas remains at equilibrium?

What is the total pressure inside the flask at equilibrium?

After the reaction is there any liquid water present? If so, how many grams? If not, why not?




(Picture) five identically sized balloons from left to right they read….

CO2 O2 He N2 CH4

Represented above are five identical balloons, each filled to the same volume at 25 Celsius and 1.0 atmosphere pressure with the pure gases indicated.


Which balloons contain the greatest mass of gas? Explain.

Compare the average kinetic energies of the gas molecules in the balloons. Explain.

Which balloon contains the gas that would be expected to deviate the most from behavior of an ideal gas? Explain.

Twelve hours after being filled, all the balloons have decreased in size. Predict which balloon will be the smallest. Explain your reasoning.

Sorry, we have a "do your own homework" policy here. You could repost this in Lab Tips if you want, but I'm not going to move this thread there, as I'm not sure how the LT mods would feel.
