0.050 mol of Sodium acetate is added to 0.500 L of 0.10 M Acetic acid. Assuming no change in volume, How much will the pH of the Acetic acid change? How much will the percent ionization of the acetic acid change?
how many mols of o2 are produced by the reaction of 156g of co2 with an excess of ko2
the volume of 4 cubic meters of gas is kept under constant pressure. its tempeture is increased from a minus 73 degrees celsius to 127 degrees celsius. What is the new volume of the gas?
How much work is done reversibly compressing one mole of an ideal gas from a starting volume of 1L to a final volume of 250mL at a constant temperature of 293K? What is the change in entropy?
What is the molarity of an NaCl solution prepared by dissolving 9.3g NaCl in sufficient water to give 350mL of solution.
