the mineral greenockite is a yellow sulfide of cadmium that is 78.0% cadmium and 22.o% sulfer. determine the emipirical formula of greenockite.
Calculate the wavelength (in nanometers) of a photon emitted by a hydrogen atom when its electron drops
What is the volume of one mole of hydrogen gas at 273 K and 760 torr? What is the volume of one mole of oxygen gas under the same conditions?
Calculate the enthalpy of the reaction: 2NO(g) + O2(g) --> 2NO2(g) given the following reactions and enthalpies of formation: 1/2 N2(g) + O2(g) --> NO2(g), delta H *A = 33.2 kJ 1/2 N2(g) + 1/2O2(g) --> NO(g), delta H *B= 90.2 kJ
calculate the minimum number of grams of C3H8(g) that must be combusted to provide the energy necessary to convert 1.61 kg of H2O from its solid form at -10.0°C to its liquid form at 80.0°C.
A 12-liter tank contains helium gas pressurized to 160atm . What size tank would be needed to contain this same amount of helium at atmospheric pressure (1atm )?
a 100.-L flask contains a mixture of methane, CH4, and argon at 25°C. The mass of argon present is 228 g and the mole fraction of methane in the mixture is 0.650. calculate the total kinetic energy of the gaseous mixture.
What is the Volume of 1.05 mol of Benzene (C6H6) at 20.7 degrees C. The density of Benzene is 0.879 g/mL.
Combustion of a 0.1000 g sample of a compound containing only carbon, hydrogen, and oxygen in excess yields 0.1953 g CO2, and 0.1000 g H2O. A separate experiment shows that the molar mass is 90 Daltons. Calculate the mass percent composition.
Calculate the electrostatic energy of the system and compare this energy to the Hydrogen atom in its ground state.
The greater volume per mole at the higher temperature indicates greater average intermolecular distances and hence weaker intermolecular forces.
calculate the molar mass of an unknown gas if 0.192 grams of the gas occupies a volume of 293 ml at 754.7 mm Hg and 22.5 degrees celsius.
Calculate the molarity of a solution made by dissolving 12.1 grams of Na2CrO4 in enough water to form exactly 520 mL
