Based on molecular structure, arrange the following sets of oxyacids in order of increasing acid strength.HClO3 ,HIO3 ,HBrO3. Explain.
The solution was acidified and treated with thioacetamide until no further change occurred. Calculate the Cu2+ and Fe2+ concentrations in the resulting solution. Ksp CuS=8.5x10^-36, Ksp FeS=3.7x10^-19
A gas containing H2S and CO2 is bubbled through methanol at 4 degrees C. From the bottom of the tank to the top, 80% of the H2S is absorbed by the methanol.
The specific heat of liquid bromine is 0.226 J/g-K. How much heat (J) is required to raise the temperature of 10.0 mL of bromine from 25.00 °C to 27.30 °C? The density of liquid bromine is 3.12 g/mL.
At 25 °C only 0.0210 mol of the generic salt AB3 is soluble in 1.00 L of water. What is the Ksp of the salt at 25 °C
At a certain temperature* (probably not 25 ºC), the solubility of silver sulfate, Ag2SO4, is 0.023 mol/L. Calculate its solubility product constant for this temperature.
A photoelectron spectroscopy experiment is conducted in which light with a wavelength of 58.4 nm is directed at a sample of rubidium, resulting in the ejection of the electron
A gaseous reaction occurs at a constant pressure of 45.0 and releases 61.0 of heat. Before the reaction, the volume of the system was 9.00 . After the reaction, the volume of the system was 3.00 .
A protein biochemist attempted to determine the amino acid sequence of a decapeptide. Use the results fromt he trypsinm chymotrypsin, and cyanogen bromide treatments to suggest the amino acid sequence.
A 0.2044 g sample of potassium hydrogen phthalate (KHC8H4O4, a primary standard) was quantitatively transferred to a 100.00 mL volumetric flask and water was added to the mark.
Write the standard line notation for each cell below. Assume all concentrations are 1.0 M and all partial pressures are 1.0 atm. IO3-(aq) + Fe2+(aq) --> Fe3+(aq) + I2(aq)
