The solubility product of BaSO4 is 1.1 x 10-10. In a 0.1 M solution of Na2SO4 that is saturated with BaSO4, the Ba2+ concentration is closest to:
10-10 M10-9 M10-7 M10-5 M10-1 M
The citric acid cycle has a catabolic role, oxidizing acetate into CO2 and generating energy, and an anabolic role. Many of the citric acid cycle intermediates serve as precursors for the biosynthesis of larger molecules. Move each of the followin..
If all four gases had initial concentrations of 0.650 M, calculate the equilibrium concentrations of the gases.
Potassium chloride, KCl, sodium sulfate, Na2SO4, glucose, C6H12O6, carbon dioxide, CO2, and ammonium phosphate, (NH4)3PO4, are soluble in water
At 1.00 atm and 23 C, how many liters of carbon dioxide are formed by the combustion of 3.40g of butane?
the pressure exerted on a 240 mL sample of hydrogen gas at a constant temperature is increased from .428 atm to .724 atm. What will the final volume of the sample be.
Energy costs vary greatly with energy source: coal @ $25.00/ton, gasoline @ a pump price of $2.00/gal, and electricity @ $0.1000/kWhr. Conventional practice is to put these on a common basis by expressing
provide a specific step by step mechanism ( with curved arrow notation) for the conversion of 4-hydroxybutanal to 4-chloro-1-butanol, and then from 4-chloro-1-butanol to tetrahydrofuran.
How many moles of PbI2 are formed? What is the concentration of KNO3? What is the remaining concentration of the reactant that was in excess?
