Consider the expansion of one mol of a monoatomic gas initially at 300 K and 10 atm. The expansion to a final pressure of 1 atm occurs in four different ways:
(a) Isothermal reversible.
(b) Isothermal irreversible against a constant external pressure of 1 atm.
(c) Adiabatic reversible.
(d) Adiabatic irreversible against a constant external pressure of 1 atm.
undergoes adiabatic expansion against a constant pressure of 78.5 kPa until the volume has increased by a factor of 3.0.Calculate q,w,delta T,delta U,and delta H.(The final pressure of the gas is not necessarily 78.5kPa.)
Based on the mass of caffeine, you can now determine the % weight of caffeine in the original tablet. How does this compare with what the packaging states?
how the isomerization from trans to cis isomer might occured. How does this compare to the isomerism of trans-[Co(NH3)4Cl2]Cl?
The activity coefficients for acetic acid and the acetate ion are 1.000 and 0.775, respectively, in a solution with an ionic strength of 0.10 M.
Patients with a high body temperature are often given "alcohol baths." The heat of vaporization of isopropyl alcohol (rubbing alcohol) is 159 cal/g. How much heat is removed from the skin by the evaporation of 190g about 1/2 cup) of isopropyl alco..
What should the molar concentrations of benzoic acid and sodium benzoate be in a solution that is buffered at a pH of 4.55 and has a freezing point of -2.0 °C.
Some MF2 is dissolved in water at 25oC to make a saturated solution. (M is a mystery metal - it's identity can be ignored.) Some of the solution is removed and tested
Tell what type of chemical reaction is represented by the following chemical equation.
Assuming that the temperature is 293K and using Redlich-Kwong equation of state, calculate the volume of ambient pressure (1 Bar) nitrogen that can be compressed into the cylinder.
Water autoionizes to produce hydronium ion and hydroxide ion. The product of the concentrations of these ions equals the water autoionization constant, Kw.
What minimum mass of succimer in milligrams is needed to bind all of the lead in a patient's bloodstream? Assume that patient blood lead levels are 0.560 mg/L , that total blood volume is 5.5 L , and that 1 mol of succimer binds 1 mol of lead.
Gold has cubic crystals whose unit cell has an edge length of 407.9 pm. The density of the metal is 19.3 g/cm3. Calculate the number of gold atoms in a unit cell. What type of cubi lattice does gold have
