Consider the chromate-dichromate equilibrium shown where the chromate ion appears yellow, and the dichromate ion is orange. determine how the equilibrium will be affected by the ph change and fill in the the statements accordingly. note: if you answer any part of this question incorrectly, a single red x will appear indicating that one or more of the terms are placed incorrectly.

increased stability in the completion of fluorine's outer shell.

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
