Draw the structure of three constitutional isomers of the organic compound C5H12.
Calculate the pH of each of the solutions and the change in pH to 0.01 pH units caused by adding 10.0 mL of 3.48 M HCl to 350 mL of each of the following solutions
Explain how many grams of sodium hydroxide should be added to the solution to produce a concentration as close as possible the desired 0.1000 M? Presume that the sodium hydroxide is carbonate-free
Consider an aqueous solution that is saturated with lead iodide, lead sulfate and 0.10 M K2SO4 (a strong electrolyte). Write mass and charge balance equations that describe the system
The Ksp of silver chloride (AgCl) is 1.8 x 10-10. If a solution had a [Cl-] = 0.0010 M, what would be the equilibrium concentration of Ag+ in the solution with some solid AgCl in contact with the solution
How many liters of water vapor are produced when 26.1g of NH4NO3 decomposes and how many grams of NH4NO3 are needed to produce 18.0L of oxygen?
If 125 g XeF[2](s) reacts completely and the gas is collected in a 50.0 L flask at 300 K, what is the pressure of the gas in atmosphere. XeF[2](s) + H[2]O(l) ---> 2Xe(g) + O[2](g) + 4HF(g)
Problem- If the heat of vaporization of ammonia (NH3) is 22.3 kJ/mol, and its boiling point is -30.0oC, what is the entropy change for the vaporization of ammonia from its liquid
If 77.0 mL of hydrogen gas is collected over water at 50.0 degrees celsuis and 763 mm Hg, what is the volume of dry gas at standard conditions? The vapor pressure of water is 92.5mm Hg at 50.0 degrees celsuis .
