One of the two most common ingredients in medication intended for the relief of excess stomach acidity is the tri-protic basealuminum hydroxide, Al(OH)3 (78.0g/mol). If a patient suffering from a duodenal ulcer display ahydrochloric acid (36.5 g/mol) concentration of 9.53 x10-3 M in his gastric juice and he produces 2.80 liters of gastric juice per day, explain how much medication (in mL) containing 2.60 g Al(OH)3per 100 mL of solution must he consume per day to neutralize the acid?
Explain the approximate volume of a 100-watt bulb is 130cm3, as well as the bulb contains 3x10-3 mol of argon. Explain how many moles of argon would be contained in a 150-watt bulb under the similar pressure and temperature conditions if the volum..
Determine the pH, percent ionization and all of the equilibrium concentrations for each of the following.
The reaction of Nitric Oxide (NO(g)) with molecular hydrogen (H2(g)) results in the production of molecular Nitrogen and water as follows; 2 NO(g) + 2 H2(g) --> N20(g) + 2 H2O(g) The experimentally determined rate-law expression for this reaction ..
