Write a net ionic equation for the precipitation reaction resulting from mixing a BaCl2 solution with a K2SO4 solution.
a tank at is filled with of carbon dioxide gas and of carbon monoxide gas. you can assume both gases behave as ideal
Why is this important and if this step was not done, how could this change your results (in other words what specifically would happen to the Ksp value?
The beaker will fill up to the 1.00 \rm L mark with the solution. Arrange the acids in increasing order of acidity.
Then you precipitate the calcium ion in solution by adding sodium oxalate Na2C2O4. The precipitate is calcium oxalate, CaC2O4. You find that a sample of limestone weighing 128.3 mg gives 140.2 mg of CaC2O4. What is the mass % of calcium in the lim..
A sample of gas at 0 celsius has a pressure of 760 mm and a volume of 2 liters. When the volume is increase to 8 liters, what will new pressure be at 0 celsius
Using molecular orbital theory, determine which of the following species are paramagnetic: O2, O^2-, O2^2-
At 700 degrees C, the total pressure of the system is found to be at 3.45 atm. If the equilibrium constant Kp for this reaction is equal to 1.52, calculate the equlibrium partial pressures of CO2 and CO gases.
What mass of sucrose should be combined with 493 g of water to make a solution with an osmotic pressure of 9.00 atm at 320 K? (Assume the density of the solution to be equal to the density of the solvent.)
When 20 mL of a 315 mL stock solution containing 2.2 M AlCl3 is diluted to 81 mL, what is the concentration of Al3+ in the new solution.
what is the vapor pressure of ethanol at 290 K when heat of vaporization is equal to 38.56 kJ/mol and the normal boiling point is 351.4?
A 1.3 g sample of C3H6O is burned completely in excess oxygen to yield CO2 (g) and H2O (l) at 25 C, releasing 41.4 kJ of energy. What is the enthalpy of formation of C3H6O?
A gas is confined to a container with a massless piston at the top. A massless wire is attached to the piston. When an external pressure of 2.00 atm is applied to the wire, the gas compresses from 4.40 to 2.20L
