You have 200 moles of nitrogen in a cylinder( having a weightless,frictionless piston). The initial temperature is 298k. The diameter of the cylinder is 0.5m. and the piston height is 1m. a.what is the mass of the weights on the cylinder? b.You heat the gas to 1000k. how high will the cylinder rise? c.How much work will the engine provide?
Hospital patients are administered oxygen from an pressurized hyperbaric oxygen chamber. 600.0 L of oxygen is compressed in a cylinder at 160.0 atm. What volume of oxygen can a cylinder supply at the given pressure.
It requires 251 J to melt 2.22 g of sodium metal at its normal melting point of 98°C. Calculate the molar heat of fusion of sodium.
She then took 15.0 mL of the stock solution and diluted it with enough water to make 65.0 mL of a final solution. What is the concentration of KOH for the final solution.
Thermodynamics equilibrium constant (K) for liquid - gas partitioning is a ratio of the analyte concentration in liquid phase to its concentration in gas phase.
What are the mass and mole fraction of all components in the mixture? What is the average molecular weight of the mixture?
Explain the Reaction, If you treat an aldehyde wiith HCN you produce a cyanohydrin. For example
The nature of the intermediates in E1 and Sn1 reactions are carbocations. If the molecule doesn't follow that formula then it has either double bonds or rings or both.
Calculate the molar solubility and the solubility of iron (II) hydroxide in pure water then in 0.125M NaOH(aq).
Solve Virial equation (the virial equation expanded in 1/ Vm )are expansions in p and 1/Vm,respectively
an aluminum rod at 55.0 degrees celsius is put into 399 grams of water at an initial temperature of 20.0 degrees celsius. If the final temperature of water and rod are 30.0 degrees celsius, what was the mass of the aluminum rod?
what is the change in enthropy for this process in kJ/K*mole. The atomic mass of oxygen is 16.00.
Determine ΔSsys separately for the volume and temperature changes and show that ΔSsys=0 for a reversible adiabatic process. Also, if the expansion had instead occurred irreversibly against a constant external pressure of 1 atm
