Mn (s) + 2 CuCl (aq) --> 2 Cu (s) + MnCl2 How many grams of Cu will be produced by 2.9 moles of Mn? Round your answer to 2 decimal places.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

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.
