Explain why BaCO3 is soluble in aqueous HCl, but BaSO4, which is used to make the intestines visible in X-ray photographs, remains sufficiently insoluble in the HCl in a human stomach so that poisonous barium ions do not get into the bloodstream.
A first order reaction has an Arrhenius constant for the reaction is 9.4 x 10^10 sec ^-1, and an activation energy of 64.4 kJ. At what temperature (in Celsius) is the rate constant equal to 0.472 sec^-1

A person is considered legally intoxicated with a blood alcohol level of 80 mg/dL. Assuming that blood plasma has a density of 1.025 g/mL, what is this concentration expressed in parts per million
If it takes 1.0 gram of solid NaOH (a strong base) to change the pH of a solution containing a strong acid from 1 to 2, how much solid NaOH (in g) would be needed to change the pH of this solution from 2 to 3? You may assume that there is no chang..
