Calculate the molar concentration of OH- ions in a 0.550 M solution of hypobromite ion (BrO-; Kb=4.0 x 10^-6). What is the pH of this solution?
Thermal equilibrium, 10.0g of Fe(s) at 98.0 degrees Celsius is placed in 50.0mL of H2O(l) at 20 degrees Celsius
Compute the difference in the ionization energies for the 1H 2H atoms(The ionization energy is the energy of the transition from the n=1 to the n=infinity energy levels for the hydrogen atom. )?
An oil bath maintained at 50.5oC loses heat to its surroundings at the rate of 4.68 kJ/min. Its temperature is maintained by an electrically heated coil with a resistance of 60 operated from a 110 V line.
How many milliliters of boiling water are required to dissolve 25g of phthalic acid? If the solution were cooled to 14oC, how many grams of phthalic acid would you recrystallize out?
An industrial vat contains 2,500 liters of an acidic aqueous solution with a pH of 3.5. How many grams of NaOH need to be added to raise the pH to 4.3?
In the preparation of amides, acid chlorides or anhydrides may be used to react with the selected amine. It is known that acid chlorides are more reactive than the corresponding anhydrides in this type of nucleophilic acyl substitution reaction.
Nicotine, a component of tobacco, is composed of C, H, and N. A 12.075 mg sample of nicotine was combusted, producing 32.757 mg of CO2 and 9.391 mg of H2O. What is the empirical formula for nicotine?
Determine the pH of 263 ml of solution which has [NH4I] = 0.300 M. Kb = 1.74 × 10-5 for NH3(aq)
