If the washes totaled 46.4 ml. how many grams of KAI(SO4)2 would be dissolved in the solution? consider the solubility begin 3.00 g/ml.
If 5.36 103 kg each of NH3, O2, and CH4 are reacted, what mass of HCN and of H2O will be produced, assuming 100% yield?
Calculate the pressure difference between CH4 and an ideal gas under these conditions. The van der Waals constants for CH 4 are a=2.300L2⋅atm/mol2 and b=0.0430 L/mol.
Calculate the energy necessary to boil 100.0 g carbon disulfide, CS2, at its normal boiling point.
A 35.0 g sample of a nonelectrolyte was dissolved is 680. g of water. The solution's freezing point was -2.80°C. What is the molar mass of the compound?
How many amps are required to produce 72.5 g of potassium metal from a sample of molten potassium chloride
Calculate the concentration of iron (II) chloride contaminant in the original groundwater sample. Round your answer to significant digits.
A gas expands and does P-V work on the surroundings equal to 281 J. At the same time, it absorbs 216 J of heat from the surroundings. What is the change in energy of the system?
Could you separate it from benzoic acid using extraction procedures? If so, please detail and explain how this can be done.
The entropy of a gas is larger than that of the liquid because the specific volume of gas is greater thus implying more mutual configurations are allowed for molecules in a gas than in the corresponding liquid.
A 1.00 g sample of an unknown gas occupies 418 mL at 23.0 oC and 715 torr. Calculate the density at 23.0 oC and the molar mass of the gas.
the set of transitions where the electron falls from a higher level to the nf = 4 state is called the Pickering series, an important series in solar astronomy. Calculate the Pickering series wavelength associated with the excited state ni = 8.
The calorimeter contains exactly 281 g of water, and the temperature increases by 1.126°C. Calculate the heat given off by the burning Mg, in kJ/g and in kJ/mol.
