Two moles of liquid water are allowed to expand into an evacuated flask such that the final pressure is 0.35atm. The experiment is kept at a constant temperature. It is found that 15.1 kJ are absorbed and the change in enthalpy is 21302 J. Calculate the values for T (in K), w, delta U, and delta S. Neglect PV quantities for water and assume ideal behavior for water vapor. (Note: when calculating the entropy change, it can be considered as two components: H20(l) at 1 atm to H20(g) at 1 atm and H20(g) at 1 atm to H20(g) at 0.35 atm.
What is the entropy change for a particle in this system if the final number of microstates is 0.819 times that of the initial number of microstates?
an aqueous solution is prepared by diluting 3.30mL acetone, CH3COH3, (d= 0.789g/mL) with water to a final volumeof 75.0 mL. The density of the solution is 0.993 g/mL. what are the molarity and the molality of acetone in this solution?
1.60 M solution(78.0 mL ) is diluted to a volume of 278 mL and a 139-mL portion of that solution is diluted using 175 mL of H 2 O ,water determine the final concentration?
what is the presentage compostition of both of the components, which is the limiting reagent (if there is) and what is the theoretical yeild of each of them.
What is the molecular formula?
A buffer solution is prepared by dissolving 1.50g each of benzioc acid C6H5CO2H and sodium benzoate NaC6H5CO2 in 150.0mL of solution.
What is the pH of the resulting solution if 50 mL of this solution is diluted to 1000 mL Kb = 0.00036.
Imagine that you have a 5.50 gas tank and a 4.00 gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch.
A compound is constituted by mass of 22.6% phosphorus, the rest being chlorine. Given that a volume of 307 mL of the gas has a mass of 1.55 g at 25 °C and 90 kPa, find the molecular formula for this compound
