What sign. info about atomic structure came from the Millikan experiment using charged oil drops
A sample of 5.20ml of diethylether (C2H5OC2H5; density=0.7134g/ml) is introduces into a 6.40L vessel that already contains a mixture of N2 and O2 whose partial pressures are PN2=0.751atm and PO2=0.209atm
It takes 254kj/mol to eject electron for a certain metal surface. What is the longest wavelength of light that can be used to eject electrons from the surface of this metal via the photoelectric effect.
One sample had a mass of 25 grams. The other had a mass of 50 grams. Would the same number of particles be ejected from each sample in the first hour?
a sample of oxygen that occupies 1.00X 10^6 ml at 575 mm hg is subjected to a pressure of 1.25 atm. what will the final volume of the sample be if the temperature is held constant?
As of the writing of this text, EPA standards limit atmospheric ozone levels in urban environments to 84ppb. How many moles of ozone would there be in the air above Los Angeles County.
Calculate the theoretical yield of C2H5Cl when 135 g of C_2H_6 reacts with 225 g of Cl_2, assuming that C_2H_6 and Cl_2 react only to form C_2H_5Cl and HCl.
What mass (in grams) of solid sucrose (C12H22O11) would need to be added to 2000 grams of water to make an ideal solution with a boiling point of 102.9°C? (Kb for water is 0.512°C/m)
an unknown gas sample is collected in a 255 ml countainer at 25c and 755 mm hg. how many moles of gas are present?
Discuss some of the underlying reasons for deviation from A=ec during the application of Beer's Law to very diluted
Calculate the expected pH values of the buffer systems from the experiments (a, b, c, d) using the Henderson-Hasselbalch equation (pH= pKa + log [A-] ). Use for pKa values: carbonic acid= 6.37 and acetic acid= 4.75.
In the synthesis of Aspirin using salicylic acid and acetic anhydride, i need a side equation for a reaction that might form salicylic acid during the workup of the product instead of acetic acid.
An experiment requires 44.0 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder. What volume of the liquid should he use?
