Problem- At a certain temperature, the solubility of strontium arsenate, Sr3(AsO4)2, is 0.0680 g/L. What is the Ksp of this salt at this temperature
a 1.33 m solution of citric acid h3c6h5o7 in water has a density of 1.10 gcm3. calculate the mole fraction of the
The charcoal from ashes found in a cave gave 3.34 14C counts per gram per minute. wood from the outer portion of a growing tree gives a comparable count of 16.0. The half life of 14C is 5700 years. How old are the ashes
Problem- Propranolol (C16H21NO2), a so-called beta-blocker that is used for treatment of high blood pressure, is effective at a blood plasma concentration of 50 ng/L. Express this concentration of propranolol in the following units:
Problem- A sealed container of 5.00L initially contains 9.84x10^-4 mol H2 and 1.38x10^-3 mol I2 (Iodine). It is kept at 350C until the reaction comes to equilibrium.
According to the VSEPR model, what are the arrangement of two, three, four, five, and six valence-shell electron pairs about an atom
The method of standard additions was used to determine nitrite in a soil ample. an aliquot of 1.00 mL of the sample was mixed with 24.00 mL of a colorimetric reagent, and the nitrite was converted to a colored product with an absorbance of 0.300.
