Benzoic acid is used to titrate an unknown base, and the pH of solution is recorded during the titration. Halfway to the ultimate endpoint of the titration, the pH of solution was recorded at 7.64. What is the value of Kb for the unknown base?
A gigantic balloon is filled to a pressure of 752 mm Hg at 12.5 ºC with pure helium gas. Once inflated, the balloon holds a total volume of 2.2 x 106 liters. How many grams of helium were used in this process?
An oxygen tank contains oxygen at a pressure of 70 kPa. When the pressure drops to 36 kPa, the temperature increases from 300 K to 350 K. If the initial volume is 9 L, what is the final volume?
At 4.00 rm L, an expandable vessel contains 0.864 mol of oxygen gas. How many liters of oxygen gas must be added at constant temperature and pressure if you need a total of 1.96 mol of oxygen gas in the vessel.
A gas is compressed from an initial volume of 5.40 to a final volume of 1.20 by an external pressure of 1.00 . During the compression the gas releases 126 of heat.
the total pressure of the system is found to be 4.50 atm At 700 degrees celsius. compute the equilibrium partial pressures of carbon dioxide and carbon monoxide if the equilbrium constant Kp = 1.52,
Each uranium atom that decays eventually results in the formation of one lead atom. Assuming that the rock did not contain any lead-206 atoms originally, find the age of the rock when the ratio of uranium to lead atoms is 8 to 1.
Within this analogy, discuss how the shielding by core electrons is analogous to putting a frosted-glass lampshade between the lightbulb and your eyes, as shown in the illustration.
What is the percent by mass of NaHCO3 in a solution containing 20 g NaHCO3 dissolved in 700 mL H2O?
Treatment of ammonia with phenol in the presence of hypochlorite yields indophenol, a blue product absorbing light at 625 nm, which can be used for the spectrophotometric determination of ammonia.
Treating 1-butanol with sulfuric acid establishes an equilibrium with 1-butyl bisulfate and water as shown.
Write the chemical equation for the overall reaction. (Part B) Identify any molecule that acts as a catalyst in this reaction. (Part C) Identify any molecule that acts as an intermediate in this reaction.
estimate the enthalpy change for the reaction between 1 mol c2h5oh as liquid ethanol, a fuel made by fermenting corn, and o2 to yield co2 and h2o under standard conditions by using bond enthalpies,
