Explain why the Rf values changed when the eluant was changed from 100% petroleum ether to a 95:5 mixture of petroleum ether-ethyl acetate. Why UV light is not a useful visualization technique in every circumstances?
Explain which of the following aqueous solutions has the strongest ion-dipole attractions: 0.3 M FeBr3, 0.6 M CaCl2, 0.5 M Ba(NO3)2, 0.2 M (NH4)2SO4, 0.9 M KOH
Ionization energy is the energy required to remove an electron from an atom in the gas phase. The ionization energy of lead is 715.0 kJ/mol.
The vapor pressure of pure propyl chloride is 347 torr at 25°C and that of pure propyl bromide is 133 torr at 25°C. Assume that the solution is an ideal solution.
if you lived in the mountains where the atmospheric pressure is 685 mm Hg, what would the partial pressure of oxygen and of nitrogen be ?
Nitrogen oxide is a pollutant in the lower atmosphere that irritates the eyes and lungs and leads to the formation of acid rain. Nitrogen oxide forms naturally in atmosphere according to the endothermic reaction: N2+O2=2NO(g) Kp= 4.1x10^-31 at 298..
A gas in a sealed container has a pressure of 125 kPa at a tempurature of 30.0 degrees celcius. If the pressure in the container is increased to 201 k Pa, what is the new tempurature?
A student found that a maximum of 0.800g silver acetate is able to dissolve in 100.0ml of water. What is the molar solubility and Ksp for the salt?
2.00 L of H2 at a pressure of 398 torr and 1.00 L of N2 at an unknown pressure. If the total pressure in the flasks is 331 torr after the stopcock is opened,
what is the wavelength of the line in the Balmer series of hydrogen corresponding to the transition for n=5 to n=2? the constant for Balmer's equation is 3.2881*10^15 s-1
A. A student places 2.10 L of water in his dormitory room, which has the volume of 4.06 x10^4 L. He seals the room and waits for the water to evaporate. At 25 deg C, the density of water is 0.997 g/mL
When a mixture of 10.0 g of C2H2 and 10.0 g of O2 is ignited, the resultant combustion reacion produces CO2 and H2O. How many grams of C2H2, O2, CO2
the molar heat of combustion of methanol, CH3OH, is -757kJ/mol. If 2g of methanol is placed in bomb calorimeter with heat capacity of 6.5 kJ/c, what is the temperature rise when the sample is combusted?
