Determine the Ka value of acetic acid at 105 degrees C from the following data: A 0.3 Molar aqueous solution of acetic acid shows a pH of 2.642 at 105 degrees C. You can use the approximation formula here because the concentration of the acetic acid is quite high.
1. Ka = 1.70 x 10^-5
2. Ka = 1.73 x 10^-5
3. Ka = 1.81 x 10^-5
4. Ka = 1.83 x 10^-5
5. Ka = 1.87 x 10^-5
assume that the pressure in the bottle was 1.5 atm, the bottle had a headspace of 20 mL, and the headspace contained 90% CO2. carbonate species and dissociation products of water.
a sample of argon gas is at a pressure of 1.24 multiplied by 10^4kpa and a temperature of 24 degrees celcius in a rigid 25-L tank. how many moles of argon does the tank contain?
170mL of an HCl solution with pH of 2.80 is added to 200mL of an HNO3 solution. The resulting pH is 1.40. What was the pH of the original HNO3 solution
Fe3O4 reacts with CO according to the reaction Fe3O4(s) + 4CO(g) --> 4CO2(g) + 3Fe(s). If 201 grams of Fe3O4 is reacted with excess CO, what mass of CO2 will be produced?
calculate the number of microstates, W, that have this energy. Make sketches of these microstates. Calculate the corresponding entropy for each state.
Fe3O4(s) + 4CO(g) --> 4CO2(g) + 3Fe(s). In this reaction, if 335.2 g Fe3O4 is reacted with excess CO, what mass of CO2 will be produced.
