A 0.5L vessel is charged with pure calcium oxalate. The vessel is evacuated to remove all substances except CaC204. The tmeperature s increased to 1200 K, so that all CaC204 decomposes to form CaO according to the reactions: The density of the gas mixture at 1200K was 0.70501 g/L. What was the mass of the calcium oxalate initially placed in the vessl? Assume that the volume of CaO in the end is negligible?
A) aqueous naoh and ch3ch2co2h B) aqeous naoh and c6h5so3h c) ch3ch2Li in hexane and ethyne d) ch3ch2Li in hexane and ethyl alcohol

If you dissolve 4 aspirin tablets in a 340mL glass of water, what is the pH of the solution and the percent dissociation?
HClO is a weak acid (Ka = 4.0 × 10-8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.087 M in NaClO?
Ethanethiol is more soluble in water because sulfer has agreater electronegativity value than oxygen. Ethanethiol is more soluble in water because it has a lower molecular mass than 1-propanol.
