At a constant pressure of 0.905 atm, a chemical reaction takes place in a cylindrical container with a movable piston having a diameter of 40.0 cm. During the reaction, the height of the piston drop is by 65.0 cm. (The volume of a cylinder is V = ?r2h, where h is the height; 1 L·atm = 101.325 J.)
a. What is the change in volume in liters during the reaction?
b. What is the value in joules of the work ? done during the reaction?
You have a gas occupying 75L at 800 torr and 315K. What is the volume if the pressure is decreased to 600 torr and the temp is changed to 127 C?
To identify a diatomic gas x2 a research carried out the following experiment: She weighed an empty 1 L bulb, then filled it with the gas at 1.10 atm and 23.0 C and weighed it again. The difference in mass was 1.27 g. Identify the gas.
Draw (in increasing energy ordering) 3 different alkenes derived from the dehydration of 1,2-dimethylcyclohexanol
Heat is lost to the styrofoam calorimeter. Assuming a 6.22 C temperature change for the reaction of HCl(aq) with NaOH(aq), calculate the heat loss to the inner 2.35-g styrofoam cup. The specific heat of styrofoam is 1.34 J/gC.
What is the Ce 3+ concentration in a solution formed by combining 50.0 mL of 0.0500 M Ce 3+ with 50.00 mL of 0.150 M IO3-? The solubility-product constant for Ce(IO 3 )3 = 3.2 x 10 E-10.

P4(s) + 6F2(g) --> 4PF3(g) How many grams of fluorine are needed to react with 6.20g of phosphorus?
I need help describing an experiment where one could measure the value of the extinction coefficient of a solution with a concentration (c mol/L) of chlorophyll in water for a given wavelength.
A 35.0ml sample gas is enclosed is in a gas tight syringe at 22 degress celcius. If the syringe is immersed in an ice bath a 0 degress celcius, what is the new gas volume.
H2s and H20 have similar structures and their central atoms belong to the same group. Yet H2S is a gas at room temperature and H20 is a liquid. Use bonding principals to expalin why this is.
