Four solution are prepared and mixed together: Start with 100.0ml of 0.100M BaCl2. Add 50.0ml of 0.100M AgNO3. Add 50.0ml of 0.100M H2So4. Add 250.0ml of 0.100M NH4. Write an equation for any reaction that occurs after each step and calculate the concentration of Ba,CL,NO3,NH4 in the final solution assuming that all reaction go to completion
Consider a perfect gas with Cvm = 28.0 J/mol-K trapped in a piston/cylinder arrangement with cross-section area of 250.0 cm^2. The gas expands irreversibly against a fixed external pressure of 1.0 atm adiabatically
could 131g of xenon gas in a vessel of volume 1.0dm^3 exerts a pressure of 20 atm at 25C if it behaves as a gas? if not what pressure would it exert? (b) what pressures would it exert if it behaved as a van der waals gas?
