Calculate deltaS, deltaStotal, and deltaSsurroundings when the volume of 84.0g of CO initially at 298K and 1.00bar increases by a factor of four in (a) an adiabatic reversible expansion, (b) an expansion againt Pexternal=0, and (c) an isothermal reversible expansion.
Take C(at constant P,m) to be constant at the value 29.14 J/molK and assume ideal gas behavior.
State whether each process is spontaneous.
If a 1000 kilogram sample of rock is 0.021% gold by mass. How much zinc is needed to react with the gold extracted from the rock?
1) How many litres of hydrogen gas will be produced by the decomposition of 90 L of water? (Assume that temperature and pressure are constant) Show ALL work.
what will be the heat capacity of a constant pressure, coffee-cup calorimeter that contains 100.0 ml of 3.0 M HCl solution? the density of the sloution is 1.098 g/mL, the specific heat capacity of the HCl solution is 4.1 J/gK and the heat capacity..
The water sample is put into a Nebulizer attached to an ICP Spectrometer and the absorbance peak measured at the proper wavelength of lead. Standards are also analyzed to produce a calibration curve for comparison
Calculate P,V and T for initial and final states of each process and produce a plot of the two processes on a P,V diagram. Without resorting to equations, explain why the result for part (b) is greater than or less than the result for part (a).

the molar enthalpy of vaporization of boron tribromide is 30.5 kJ/mol and its normal boiling point is 91 degrees celsius. what is the vapor pressure of BBr3 at 27 degree celsius ( R=8.314 kJ/mol)?
Write a brief procedure that would have been used to carry out the titration. Just include the key steps (terms and measurements). c. What was the average volume of Ca(OH)2 used? d. Calculate the concentration of the HCI sample.
If the colder block orginially weighed 200g and the warmer one 100g. calculate the final temperature and the entropy change of the universe for this process
When are covalent bonds most likely to form? a. between 2 atoms with a high ionization energy b. between 2 with a low ionization energy. c when one atom high and other low d. no correct choice. (I'm leaning towards a.)
Even with a drying tube, leaving phenylmagnesium bromide exposed to air will eventually lead to its decomposition. Why? What is the product of this decomposition pathway?
