Asealed tank contains 29 moles of an ideal gas at an initial temperature of the pressure of the gas is increased until the final pressure equals 1.9 times the initial pressure. the heat capacity at constant pressure of the gas is what is the heat absorbed by the gas? let the ideal-gas constant r = 8.314 j/(mol • k).

Explain the comparisons between nature and packingtown that appears on pages 81 and 82 answer

Wave functions describe orbitals in a hydrogen atom. each function is characterized by 3 quantum numbers: n, l, and ml. if the value of n = 2: the quantum number l can have values from to . the total number of orbitals possible at the n = 2 energy level is .
