When α-iron is subjected to an atmosphere of hydrogen gas, the concentration of hydrogen in the iron, CH (in weight percent), is a function of hydrogen pressure, (in MPa), and absolute temperature (T) according to Furthermore, the values of D0 and Qd for this diffusion system are 2.7 × 10-7 m2/s and 13 kJ/mol, respectively. Consider a thin iron membrane 1.6-mm thick that is at 253°C. Calculate the diffusion flux [in kg/(m2-s)] through this membrane if the hydrogen pressure on one side of the membrane is 0.14 MPa, and on the other side 7.1 MPa, given that the density of iron is 7.87 g/cm3.

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
