The lower flammability limit (LFL) for a gas is the minimum concentration of the gas, in air, below which there is too little fuel to support combustion; For propane, the LFL is 2.1 mol-%; What is the mol fraction of propane in the air at the stoichiometric concentration?
What is the molar mass of lysine if 750.0 mL of a solution containing 8.60 g of lysine has an osmotic pressure of 1.918 atm? T = 25.0°C
Solid iron reacts with chlorine gas to produce iron(III) chloride. If 10.0 grams of iron reacts with excess chlorine gas and 18.5 grams of iron(III) chloride is produced
How many moles of an ideal gas would occupy a 25.0 liter container when the temperature is 22.0° C and the pressure is 646 torr?
Explain briefly how you could prepare the buffer solution in (a) if you had available the solid salt of the only one member of the conjugate pair and solution of a strong acid and a strong base.
The smallest unit of charge is -1.6× 10-19 C, which is the charge (in coulombs) of a single electron. Robert Millikan was able to measure the charge on small droplets of oil by suspending them between a pair of electrically charged plates.
A freeway has 10,000 vehicles per hour passing a house 200 m away. Each car emits an average of 1.5 g/mi of NOx, and winds are blowing at 2 m/s across the freeway towards the house.
What is the molar concentration of the excess reactant once this reaction has finished? (40%)
To make a phosphate buffer at pH 9.6 starting with 1L of 10 mM phosphoric acid (H3PO4; pKs are of 2.15, 6.82, and 12.38 determine how much KOH ), you could add?
use the activity series of metals to write a balanced chemical equation for this single replacement reaction
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.
Calculate the standard reaction enthalpy for the formation of boron trifluoride, which is widely used in the chemical industry:B2O3(s) + 3CaF2(s) > 2BF3(g) + 3CaO(s).
